Update Documentation: Changes in Version -303 -402 -502
The special version -303 -402 -502 incorporates an extended operating frequency range for the voltage memory and the power swing blocking function in addition to the features and functions of the standard versions -302/-303 -401/-402 -602.
Distance Protection Distance and Directional Measurement The frequency range of the voltage memory is extended. The voltage memory is enabled, if the measured frequency satisfies the following condition:
0.95 × fnom < f < 1.05 × fnom
Power Swing Blocking
When power swing blocking is activated, a distance trip in zones 1 to 5 is prevented if there are power swings in the network.
Three-pole distance protection starting with and without ground initiates the start delay of the power swing blocking function. The start delay is intended to enable release in zone 1. After the settable start delay has elapsed, the device checks to determine whether the phase-to-phase voltage 1VA-B is greater than 0.1 × Vnom . If this condition is satisfied, then the apparent power S is calculated from the quantities 1VA-B and IA-B . The amount of change in apparent power as referred to the apparent power at that moment is determined every 40 ms.
S1 - S 2 S2 S1: apparent power at time t1 S2: apparent power at time t1 + 40 ms If the difference is greater than the set value, a blocking signal is formed to block the distance trip for zones 1 to 5. This signal is extended by the settable release delay. Power swing blocking is blocked if the monitoring function of the voltage-measuring circuit operates.

3 Operation
3.1 Modular Structure
3.2 Man-Machine Communication
The PD 521, a numerical protection device, is one of the pieces of instrumentation in Subsystem P of the Integrated Protection and Control System for Substations (ILS). The devices that are part of this system are built from identical uniform hardware modules. Figure 1 shows the basic hardware structure of the PD 521 distance protection device.
The following interfaces are available for the exchange of information between operator and device: ¨
Integrated local control panel
¨
PC interface
¨
ILSA interface
Each piece of information and each parameter is coded with an ‘address’ consisting of two two-digit decimal numbers x and y. Changing x or y allows selection of any desired address for display or where necessary modification of the information stored at that address. (Please refer to Chapter 6.) The addresses are standardized for all systems with the advantage that the same information is coded with the same address in each device type. The entire address range is divided into the following three groups:
1 Basic hardware structure
The input transformers and optical couplers convert the external analog and binary variables - electrically isolated to the internal processing levels. Commands and signals generated within the device are accessible via floating contacts. The external auxiliary voltage is applied to the power supply module which provides the voltages required internally.
¨
Parameters: This group contains all set values including the device identification data, the configuration parameters for adapting the device interfaces to the system and the function parameters for adapting the protective function to the process. All values of this group are stored in a non-volatile memory, that is the values will be preserved even if the power supply fails.
¨
Operation: This group includes all information relevant for operation, such as measured operating values and binary signal states. This information is updated periodically and consequently is not stored. In addition, various control parameters are grouped here, for example those for resetting counters, memories and displays.
¨
Events: The third group is reserved for the recording of events. Hence all information contained in this group is stored. In particular the start/end signals during a fault, the measured fault data as well as sampled fault records are stored here and can be read out at a later time.
The appendix, section C, documents the addresses of the numerical protection device PD 521. This address list is complete and thus contains all addresses used with the PD 521.

3 Operation (continued)
3.3 Distance Protection The secondary phase currents and voltages of the system transformer are fed to the PD 521 and – electrically isolated – are converted to normalized electronics levels. The analog quantities are digitized and are thus available for further processing. Settings that do not refer to nominal quantities are converted by the PD 521 to nominal quantities. The nominal current of the PD 521 must be set for this purpose. The connection arrangement of the distance protection measuring circuit on the PD 521 must be set.

From these currents (IA, IB and IC) the phase-to-phase currents IA-B, IB-C and IC-A are formed. The current with the highest magnitude (IP,max) and the current with the intermediate magnitude (IP,med) are determined from the phase currents. The ground current 1IN is calculated by summation of IA, IB and IC. The phase-to-phase voltages 1VA-B, 1VB-C and 1VC-A are formed from the digitized phase-to-ground voltages 1VA-G, 1VB-G and 1VC-G and the neutral displacement voltage 1VN-G.

3.3.1 Fault Detection Logic The purpose of distance protection fault detection logic is phase-selective short-circuit detection. Fault detection logic is divided into the following areas: ¨
Overcurrent detection
¨
Ground fault detection
¨
Undervoltage detection
¨
Underimpedance detection
The fault detection decisions of the individual areas are linked by fault detection logic. Short-circuit currents that are greater than the maximum operating load currents can be detected by overcurrent detection logic. Undervoltage detection logic is provided for short circuits that cannot be detected by overcurrent detection logic. Ground fault detection logic distinguishes between grounded and ungrounded faults.
The fault detection logic function starts the timer stages of the trigger levels and – as a function of the phaseselective fault detection decision – selects the measuring loop in which the fault impedance is determined. Fault detection logic is blocked in the following cases: ¨
if protection is disabled from the local control panel or through appropriately configured binary signal inputs;
¨
if measuring-circuit monitoring detects a fault in the voltage-measuring circuit.
Protection can only be deactivated or activated through binary signal inputs if the M A I N : D e a c t i v a t e p r o t . E X T and M A I N : A c t i v a t e p r o t . E X T functions are both configured. When only one or neither of the two functions is configured, this is interpreted as “Protection externally activated.” If the triggering signals of the binary signal inputs are implausible, as for example when they both have a logic value of “1,” then the last plausible state remains stored in memory.

3 Operation (continued)
Overcurrent Detection Logic Overcurrent detection logic monitors the phase currents for values in excess of the threshold values I>> and I>>>. The I>> threshold can be set. I>>> is 2 × I >> . The thresholds are identical for all three phases. The output signals of the I>> trigger assume a logic value of "1" if the threshold is exceeded in two consecutive halfwaves. Overcurrent detection is delayed by the set time tI>> if the current is below 5 × I>>. Thereby, false fault detection decisions caused by inrush currents on switching can be suppressed for lines with connected transformers. In the case of the I>>> trigger only one halfwave must exceed the threshold for the output signals to assume a logic value of "1."
If I>> is exceeded in one phase, then it is sufficient for overcurrent detection if I>>> is exceeded in the other phases. In this case the fault detection time is shortened since there is no longer any need to wait for the second half-wave. Evaluation of the trigger decisions is a function of the type of neutral-point treatment set in the PD 521. If isolatedneutral/resonant-grounded or short-time grounding is set, then I>> overcurrent detection occurs in the phase(s) in which the I>> threshold is exceeded. With the setting impedance-grounded the following condition must also be satisfied:

Ground Fault Detection Logic
Ground fault detection logic monitors the average magnitude of the ground current 1IN and the neutral-point displacement voltage 1VN-G for values exceeding set thresholds.
5% of the current maximum phase current is added to the set threshold IN>, which means that the operate value of the ground current function increases with an increasing phase current level as a form of stabilization.

Even in the case of a single-phase fault, that is, in the event that only one base point is detected, ground fault starting will occur, but not until tIN> has elapsed.
The ground fault detection mode is a function of the neutral-point treatment set in the PD 521. ¨
¨
MAIN: Neutral-point treat(ment) Low impedance-grounding Ground fault starting SG occurs with this setting when the threshold of the IN> or VN-G> trigger is exceeded. MAIN: Neutral-point treat(ment) Isolated neutral/resonant-grounding If the setting isolated neutral/resonant-grounding is selected, instantaneous starting SG occurs when there is multiple phase-to-ground fault detection if the threshold value of the IN> or VN-G> trigger is exceeded.
¨
MAIN: Neutral-point treat(ment) Short-duration grounding Operation in this mode corresponds to operation with the setting isolated neutral/resonant-grounding except that timer stage tIN> is started when the IN> or VN-G> trigger operates. In the case of a sustained ground fault the timer stage tIN> remains in the elapsed state due to the operating trigger VN-G>>. If the ground fault changes to a phase-to-ground fault then ground fault starting operates without delay when the threshold of the IN> or VN-G> trigger is exceeded.

Ground Fault Starting Signals Signals are derived from ground fault detection trigger decisions. If neutral-point treatment is set for Low impedance-grounding, then the following signals are issued: ¨
When VN-G>> is exceeded, S T A R T : V N - G > > t r i g g e r e d is signaled.
¨
By selecting the appropriate setting the user can specify whether a “trip” should occur after the timer stage tVN-G>> has elapsed.
With the settings Isolated neutral/resonant-grounding or Short-duration grounding the M A I N : G r o u n d f a u l t signal is issued after tVN-G>> elapses (see Figure 6) if there is no multi-phase starting.
Enabling Undervoltage and Underimpedance Detection Logic
Undervoltage and underimpedance detection logic are enabled by I>(Imin) in the corresponding measuring systems. In order to control contention problems when current and voltage appear at the same time (branch voltage transformers), enabling of the measuring systems is delayed by 15 ms. In isolated-neutral systems or resonant-grounded systems, one of the two phases may carry just a small load current falling below the base point current I>(Imin). In this case, the undervoltage decisions are enabled if the V< condition is met in two phases whereas the I> condition is satisfied in one phase only. This extended enabling logic will operate only for the neutral-point treatment settings Isol./reson. w. start. P-G and Shortduration grounding.

Monitoring the Voltage-Measuring Circuits
The voltages used by distance protection as measured variables are monitored by the voltage-measuring circuit monitoring function for plausibility. However, this does not replace the auxiliary contact of the voltage transformer m.c.b., which is absolutely necessary in the case of activated undervoltage and underimpedance starting. Monitoring of the voltage-measuring circuits is based on the following criteria: ¨
Monitoring the phase-to-phase voltages for voltages that fall below the default threshold of 0.4 × Vnom . This monitoring function is enabled when the phase current is greater than 0.05 × I nom or for the “closed“ position of the circuit breaker provided that MON: Meas . volt. c irc uit is set to Vneg w.

¨
Monitoring the negative-sequence component of phase-to-ground voltages in accordance with the definition of the symmetrical components. Monitoring is enabled when a phase-to-ground voltage exceeds the default threshold of 0.7 × Vnom / 3 . In addition to this criterion, a minimum current having the default threshold setting of I > 0.05 × I nom or the closed position of the circuit breaker can be used as enabling criteria. If there is an enable, the absolute value of the negative-sequence component of the voltage system is determined in accordance with the definition of symmetrical components. Vneg = a = e j 120

If one of the monitoring functions described above operates, then distance protection is blocked and the device switches to backup overcurrent time protection – if the appropriate setting was selected. In addition, the monitoring signal “M O N : M e a s . v o l t .

A communication malfunction or failure leads to a protective signaling block. If protective signaling is carried out by a signal transmission or communication device, the device’s fault signal can be connected. In the case of protective signaling via pilot wires or in the operating mode referred to as "reverse interlocking," an internal monitoring function detects any fault in the communication channel. Protective signaling can be operated in seven different modes. The following operating modes require a signal transmission device:
When there is a “Distance trip zone 1" a signal is sent to the remote station’s protection device. Upon receipt of the signal by the remote station, the remote station’s circuit breaker is tripped.

In this case the C B F : C B f a i l u r e signal is issued.
3.9 Ground Fault Direction Determination Using Steady-State Values Ground fault direction determination using steady-state values requires the neutral-point displacement voltage formed from the three phase-to-ground voltages - and the ground current as measured variables. A special transformer is provided in the PD 521 for the residual current. The current transformer is designed specifically for this application so that it has a low phase-angle error. When there is a trip of the voltage transformer circuit breaker, ground faults can be determined by steady-state evaluation of the ground current. The user can specify whether both ground current and displacement voltage will be evaluated (steady-state power) or if only the ground current will be evaluated (steady-state current). The switch from steady-state power evaluation to steady-state current evaluation can also be carried out through a binary signal input – given appropriate configuration. When switching from steady-state power to steady-state current evaluation or vice versa, the outputs of the nonactive function are blocked.

3.10 Starting Signals and Tripping Logic The distance protection and backup overcurrent time protection starting signals are linked to form common starting signals. The number of general starting signals (GS) is counted.
The following signals of the protection device are combined to form common trip signals and trip commands: ¨
Distance trips for zones 1 to 6
¨
START: Trip VN-G>>
¨
MON: Trip by Ineg
¨
BUOC: Tripping signal
¨
SOTF: Trip after manual close
If the PD 521 is operating with protective signaling, then a zone 1 trip can be issued by protective signaling in the "Direct transfer trip underreach" and "PUTT (Permissive underreaching transfer tripping)" operating modes. In all other protective signaling modes an enable must be issued by protective signaling. If protective signaling is not ready, then the zone 1 distance trip is automatically enabled. The trip signals are present only as long as the conditions for the signal are satisfied. If a general starting condition exists, then a non-delayed, three-pole "starting trip" can occur by triggering an appropriately configured binary signal input. A trip command can be issued not only by the protection function but also through a control parameter (address 03 40) or an appropriately configured binary signal input, in which case it is issued for 100 ms. 68 Starting signals
The trip commands can be blocked by a control parameter (address 21 12) or an appropriately configured binary signal input. The trip signals are not affected by the block. If trips are blocked this is indicated by a steady light at yellow LED indicator H3 on the local control panel and by output relay K8 if configured accordingly. The phase-selective trip commands, the general trip command and the final trip are counted. The counters can be reset either individually or as a group.

In order for these quantities to be displayed as primary values, the primary nominal current of the current transformer or the nominal transformation ratio multiplied by the nominal device current and the primary nominal voltage of the voltage transformer must be set in the PD 521. The measured data are updated at 1 s intervals. Updating is interrupted if a general starting state occurs.

The date and time assigned to a fault when the fault begins can be read out from the signal memory on the local control panel or through the PC and ILSA interfaces. The time information assigned to the signals can be called up only through the PC or ILSA interfaces. The fault recordings are stored in non-volatile memory.

3.14.1 Fault Logging
3.14.2 Measured Fault Data
Protection signals during a fault, including the signals during the settable pre-fault and post-fault times, are logged in chronological order with reference to the specific fault. A total of five faults, each involving a maximum of 64 start or end signals, can be stored in a non-volatile ring memory -- the signal memory. After five faults have been logged the oldest fault log will be overwritten, unless faults have been erased in the interim. If more than 64 start or end signals have occurred during a single fault, then “Signal mem. overflow” (address 35 01) will be entered as the last signal. If time and date are changed during the pre-fault time, the signal FREC: Faulty tim e tag is generated.
When there is a fault in the network the PD 521 determines the following measured fault data:
In addition to the fault signals, the measured fault data are also entered in the signal memory. The fault logs can be read on the local control panel or through the PC or ILSA interfaces.

The fault must last for at least 60 ms so that the fault data can be determined. The fault data are determined using the measured variables Imeas and Vmeas selected by the distance protection function, if the fault is detected by distance protection. A phase current is selected as the fault current in accordance with the selected measuring loop. In the case of multi-phase starting this is the current of the leading phase in the cycle. If the measuring-circuit voltage Vmeas < 200 mV, the set angle a is used to determine the fault reactance. The set angle a is then also displayed as the fault angle. The primary short-circuit reactance is calculated from the per unit short-circuit reactance using the set primary nominal current and voltage transformer data. The ground fault data are only determined if a phase-toground loop has been selected for measurement by the distance protection function. The geometric sum of the three phase currents is displayed as the fault current. The ground fault angle is the phase displacement between ground fault current and selected measuring voltage. If the fault is detected by the backup overcurrent time protection function, then only the fault current can be determined. The maximum phase current is displayed. The F L O C : S t a r t d e t e r m i n a t i o n setting determines the actual time during a fault when the fault data are determined and whether output of fault location shall take place. The following settings are possible:
¨
FLOC: Start determination Fault end Determination at the end of the fault. The measured F L O C : F a u l t l o c a t i o n value is output.
¨
FLOC: Start determination Fault end / trip during t1) Determination at the end of the fault. Output of the measured “F L O C : F a u l t l o c a t i o n ” value only occurs if a trip occurred in distance protection zone 1.
¨
FLOC: Start determination Trip or trigger Determination when a trip starts or a correspondingly configured signal input is triggered. Output of the measured F L O C : F a u l t l o c a t i o n value only occurs if a trip occurred or if the binary signal input was triggered. If neither a trip was issued nor the binary signal input was triggered, the fault values are stored at the end of the general starting state. There is then no output of fault location.
In order for the fault location to be determined in percent of line length and in km, the value of the line reactance – 100% of which corresponds to the line section being monitored – and the value of the corresponding line length in km must be set in the PD 521. Fault current and voltage are displayed as per-unit quantities referred to Inom and Vnom. If the measured or calculated values are outside the permissible measuring range, the “overrange” indication (-..-) appears. Permissible current measuring range: Permissible voltage measuring range:

If the thresholds are not reached or if distance protection starting does not last as long as 60 ms, the symbol for “not measured” (....) is displayed. After the reset key (R) on the local control panel is pressed, the symbol for “not measured” (....) is displayed at the respective addresses. However, the values are not erased and can continue to be read out through the PC and ILSA interfaces.

3.14.3 Fault Data Acquisition The phase currents and the phase-to-ground voltages are recorded before, during and after a fault. The times for recording before and after the fault can be set. A maximum time period of 4.35 s / 3.33 s (including the prefault and post-fault recording times) is available for recording if the nominal frequency is 50 Hz / 60 Hz.. If the maximum recording time of 4.35 s (or 3.33 s) is exceeded, the analog values for the oldest fault are overwritten, but not the binary values. If more than five faults have occurred since the last reset, then all data for the oldest fault are overwritten.
Fault recording can also be started manually from the local control panel or externally through a binary signal input. The analog data of the fault record can only be read out through the PC or ILSA interfaces. When the analog data are sampled the neutral displacement voltage VN-G is calculated from the phase-to-ground voltages and the ground current IN is calculated from the phase currents. When the supply voltage is interrupted or after a warm restart, the values of the last fault remain stored.

3.15 Self-Monitoring and Fault Diagnosis Comprehensive monitoring routines in the PD 521 distance protection device ensure that internal faults are detected and do not lead to malfunctions of the protection system.
If at least one entry is stored in the monitoring signal memory, this fact is signaled by the red LED indicator H1 on the local control panel. Each new entry is indicated by a flashing light. The combined signal for all warnings may also be issued via an output relay. The output relay responds as long as an internal fault is detected.
After the supply voltage has been turned on, various tests are carried out to verify full operability of the PD 521. The local control panel display shows which test is currently being run. If the PD 521 detects a fault in one of the tests, then startup is terminated. The display shows which test was running when termination occurred. No control actions may be carried out. A new attempt to start up the PD 521 can only be initiated by turning the supply voltage off and then on again. After startup has been successfully completed, cyclic selfmonitoring tests will be run during operation. In the event of a positive test result, a specified monitoring signal will be issued and stored in a non-volatile memory – the monitoring signal memory – along with the assigned date and time. A listing of all possible entries in this monitoring signal memory is given in the address list (see Appendix C). The memory depth allows for a maximum of 30 entries. If more than 29 monitoring signals occur without interim memory clearance, the M O N : M o n i t o r s i g . m e m o r y signal “Overflow” (address 90 12, value 9) is entered as the last entry.
82 “Warning” signal
The number of entries stored in the monitoring signal memory can be determined by reading the M O N : N o . o f m o n . s i g n a l s counter (address 04 19). The monitoring signal memory can only be cleared manually by a control action. Entries in the monitoring signal memory are not cleared automatically even if the corresponding test has a negative outcome in a new test cycle. The contents of the monitoring signal memory can be read from the local control panel or through the PC or ILSA interface. The time information assigned to the individual entries can be retrieved via the PC or ILSA interface only.

3 Operation (continued)
The response of the PD 521 to monitoring signals takes one of the following forms depending on the signal. ¨
Signaling Only If there is no malfunction associated with the monitoring signal, then only a signal is issued, and there are no further consequences. This situation exists, for example, when internal data acquisition memories overflow.
¨
Selective Blocking If a fault is diagnosed solely in an area that does not affect the protective function, then only the affected area is blocked. This would apply, for example, to the detection of a fault on the ILSA bus interface module or in the area of the PC interface.
¨
Warm Restart If the self-monitoring function detects a fault that might be eliminated by a system restart, for example a fault in the hardware, then a procedure called a warm restart is automatically initiated. During this procedure, as with any startup, the computer system is reset to a defined state. A warm restart is characterized by the fact that no stored data and, in particular, no setting parameters are affected by the procedure. A warm restart can also be triggered manually by control action. During a warm restart sequence the protective function and communication through serial interfaces will be blocked. If the same fault is detected after a warm restart has been triggered by the self-monitoring system, then the protective function remains blocked but communication through the serial interfaces will usually be possible again.
¨
Cold Restart If a corrupted parameter subset is diagnosed in the checksum test during self-monitoring, then a cold restart is carried out. This is necessary because the protection device cannot identify the corrupt parameter within the set. A cold restart has the result that all internal memories are returned to a defined state. After a cold restart, this means that all settings of the protection device have been discarded. The default settings as found in the address list in the column headed “Default” apply instead (see Appendix C). In order to establish a safe initial state, the default values have been selected so that the protective function is blocked. Both the monitoring signal that triggered the cold restart and the value indicating parameter loss (address 90 28) are entered in the monitoring signal memory.
89521-302/-303-401/-402-602 / AFSV.12.06470 EN
If the protective function is blocked, the condition is signaled with a steady light by the yellow LED indicator H3 on the local control panel or, if desired, via an output relay configured accordingly.
84 “Blocked/faulty” signal
3.16 Serial Interfaces The PD 521 has a PC interface as standard component. The ILSA interface is optional. Both interfaces allow setting and readout. When tests are run on the PD 521 it is advisable to activate the test mode (address 03 12 or binary signal input) so that the PC or the control system evaluates all incoming signals accordingly.

4 Design
The PD 521 is mounted in an aluminium case. Connection is via threaded terminal ends. The case is suitable for either wall surface or flush panel mounting. The angle brackets and connector blocks are adjustable for mounting in the chosen configuration. Figures 88 and 89 show the case dimensions and fixture positions. For flush mounting, a cover frame is available (see Installation and Connection). Regardless of the design version, the PD 521 – as the other device types of the ILS-P system – is equipped with a standard local control panel. In order to protect the device according to the specified degree of protection, the local control panel is covered with a tough film. In addition to the essential control and indication elements, a parallel display consisting of a total of 8 LED indicators is also incorporated into the local control panel. The meaning of the various displays is shown in plain text on a label strip.
The label strip is located in a pocket accessible from the rear of the front panel. It can be replaced by user-specific labels. A further label strip lists the addresses for operation-related protection information and can also be replaced by a strip with customized labeling. The processor module with the local control module is attached to the reverse side of the removable front plate and connected to the I/O module via a ribbon cable. The I/O module incorporates the power supply, the input transformers and the power supply converters as well as eight output relays and two optical couplers for binary signals. The serial interface -X6 for parameter setting via a PC is set into the front panel. The optional ILSA interface -X7 and -X8 or -X9 (Order extension number -302 and up) is located on the underside of the case.

5.1 Unpacking and Packing
5.3 Location Requirements
The PD 521 is packaged separately in its own carton and shipped inside outer packaging. Use special care when opening the cartons and unpacking the equipment, and do not use force. In addition, make sure to remove from the inside carton the Supporting Documents supplied with each individual device.
The PD 521 has been designed to conform to the standard EN 60255-6. Therefore when choosing the installation location it is important to make sure that it provides the conditions specified in the Technical Data (see Chapter 2). Several important conditions are listed below.
The design revision level of each module included with the device in its as-delivered condition can be determined from the list of modules provided in the ‘Assembly List’ supplied with the device (see ‘Components/Modules’). This list should be carefully saved.
Climatic Conditions
After unpacking the equipment, inspect it visually for sound mechanical condition after transportation. If the PD 521 is to be shipped, both inner and outer packaging must be used. If the original packaging is no longer available, make sure that packaging conforms to DIN ISO 2248 specifications for a drop height £ 0.8 m.
¨
Ambient temperature: - 5 to + 55°C
¨
Air pressure: 800 to 1100 hPa
¨
Relative humidity: 45 to 75 % (annual mean), up to 56 days at £ 95% and 40°C. The relative humidity must not result in the formation of either condensed water or ice in the PD 521.
¨
Ambient air: The ambient air must not be significantly polluted by dust, smoke, gases or vapors, or salt.
5.2 Checking Nominal Data and Design Type The PD 521 nominal data and design type can be determined by consulting the type identification label (see Figure 90).

5.4 Installation The case and mounting dimensions are given in Chapter 4. The PD 521 is delivered in the wall surface mounting or the flush panel mounting configuration depending on the order specifications. When the PD 521 is being installed in a cabinet door, for example, special sealing steps must be followed in accordance with the IP 51 protection required for the cabinet. Should the PD 521 mistakenly have been ordered for surface instead of flush mounting, the connector blocks and angle brackets can be adjusted as shown in Figure 91. ¨ The two angle brackets D need to be removed after undoing bolts C (three each on the upper and lower face). Subsequently, bolts C are repositioned and tightened.

For wall surface mounting, the leads to the PD 521 are usually run along the front side of the mounting level. If the wiring is to be behind, an opening can be provided below or above the terminal strip (see Figure 93).
For flush mounting, the PD 521 must be fastened using the four bolts provided within the packing carton. The cutout edges and the bolt heads can be concealed using a cover frame with a snap-on fixture to the bolt heads (see Figure 94).

5.5 Protective and System Grounding
5.6 Connection
The device case must be reliably grounded for reasons of protective equipment grounding. This grounding step is also absolutely essential for proper operation of the device and is thus equivalent to system grounding. Potentials that need to be grounded from an operational standpoint are already properly connected to the equipment ground inside the unit.
5.6.1 Measuring and Auxiliary Circuits
Holes for the grounding connection are located in the two mounting brackets of the PD 521 and are labeled accordingly.
Copper leads having a 2.5 mm2 cross-section are generally suitable as connecting leads between the current transformers and the PD 521. Under certain conditions the connecting leads between the main current transformers and the PD 521 must be short and have a larger cross-section in order to handle the permissible burden on the main current transformers. Copper leads 2 having a 1.5 mm cross-section are sufficient for the binary signal inputs, voltage inputs, the signaling and triggering circuits, and for the power supply input.
A ground connection assembly kit is supplied with the unit. The ground connection must be assembled as shown in Figure 95. Grounding must be low-inductance.
Connect the PD 521 in accordance with the terminal connection diagram specified on the type identification label. The terminal connection diagram is included in the Supporting Documents supplied with the unit and is also given in Appendix E of this manual.
As a general principle, all connections run into the system must have a defined potential. Pre-wired connections that are not used must be grounded. Connecting the Measuring Circuits of Distance Protection The current and voltage transformers must be connected to the protection device in accordance with the standard schematic diagram shown in Figure 96. The default and factory setting of the protection device is based on this current transformer connection scheme (“line-side grounding“). Connection of the current transformers in opposition (“busbar-side grounding“) can be taken into account when making the settings (see Section 7). The PD 521 is always equipped with four current inputs.

Connecting Protective Signaling Depending on the operating mode selected, either a signal transmission device or pilot wires are required for signal transmission. Transposed lines should be used for the pilot wires. Two or four lines are required. If only two lines are available, there must be an all-or-nothing relay in each station for coupling received and transmitted signals. The coils of the all-or-nothing relays must be designed for half the loop voltage. Figure 97 shows the connection with two lines and Figure 98 the connection with four lines. The protective signaling transmitting relay can be set to Transm. relay break contact or Transm. relay make contact. In the first case the break contact must be wired and in the second case the make contact. The figures show the connection for the setting Transm. relay break contact (K1 and K2 are shown in the de-energized state). In addition, the PD 521 can also function together with the SV 35A protective signaling system or the V 34 comparator relay if care is taken to ensure that at least a pilot wire current of 10 mA is flowing.

5 Installation and Connection (continued)
Connecting Steady-State Ground Fault Direction Determination If the PD 521 is to function using ground fault direction determination by steady-state values, then the current transformer T4 must be connected to a window-type current transformer or a current transformer in Holmgreen configuration. If the metal sheath of the cable is led through the window-type transformer, then the overhead ground wire must be led (insulated) through the core again before it is connected to ground. The cable sealing end must be attached so that it is insulated from ground. In this way any currents flowing through the sheath will not affect measurement.
94
For ground fault direction determination by steady-state values, the neutral-point displacement voltage - formed from the three phase-to-ground voltages - and the ground current are required as measured variables. Figure 99 shows the standard connection of ground fault direction determination by steady-state values. For this connection “forward/LS“ is displayed if a ground fault occurs on the line side. A different connection scheme for the current transformer can be allowed for by making the appropriate setting (see Chapter 7).

5 Installation and Connection (continued)
Connecting the Auxiliary Voltage Before connecting the auxiliary voltage VA for the PD 521 power supply, make sure that the nominal value of the auxiliary device voltage agrees with the nominal value of the auxiliary system voltage.
In the upper portion of the I / O module, between output relay and current input transformers, are plug-in jumpers, which are plugged in as shown as follows, depending on the desired auxiliary voltage range.
Polarity reversal protection is provided in the form of a rectifier bridge. To preserve uniformity with other protection devices (L+ on terminal with smaller number), L+ should therefore be connected to terminal 13. The PD 521 has an auxiliary voltage supply that can be switched between ranges and is factory-set for the voltage range of VA,nom = 110 to 250 V DC or 100 to 230 V AC.
!
Before changing the auxiliary voltage range, turn off any connected auxiliary voltage. The components located behind the front panel are energized!
The voltage range is switched by repositioning plug-in jumpers on the I / O (input / output) module. After loosening four bolts on the front side of the front panel, the local control module (front panel and processor module) can be removed once the following plugs have been removed first: ¨ The tab connector on the case
100 Plug-in jumpers positioned for an auxiliary voltage of 110 to 250 V DC or 100 to 230 V AC (view from component side)
101 Plug-in jumpers positioned for an auxiliary voltage of 24 to 60 V DC (view from component side)
¨ The tab connector on the lower circuit board (I/O module) ¨ The ribbon cable connecting the local control module (front panel and processor module) with the I/O module ¨ The ribbon cable connecting the local control module with the optional ILSA interface (to fiber optics or to wire)
!
96
Where possible, disconnection of the ribbon cable between the processor module and the I/O module should be avoided. Should disconnection have occurred, however, then the device needs to be re-initialized by way of a cold restart.

5.6.2 Binary Control Inputs
5.6.4 PC Interface
Before connecting the control voltage Vin,nom for the binary inputs in the PD 521, check to see whether the control voltage Vin,nom is within the operating range of 24 V DC to 250 V DC. Polarity reversal protection is provided in the form of a rectifier bridge.
The PC interface is provided so that PS 441 parameters can be assigned from a personal computer (PC). The special connection cable available as an accessory is the only type of PC connection that may be used.
5.6.3 Tripping and Signaling Circuits
!
The freely configurable output relays and their connections are shown in the terminal connection diagram. The output relays are suitable both for tripping and signaling purposes.
The PC interface is not intended for permanent connection. Consequently the socket does not have the extra insulation from circuits connected to the system that is required per VDE 0106 Part 101. Therefore when connecting the connection cable make sure that you do not touch the socket contacts.
After completing device control (parameter setting) via the PC, disconnect the PC connection cable on the interface socket to restore the specified degree of device protection. 5.6.5 ILSA Interface The ILSA interface is provided for stationary linking of the protection device to a control system for substations or to a central substation unit. Connection is - dependeing on the design of the ILSA interface - via a special connector with a fiber-optic conductor or via an RS 485 interface with twisted copper wires. The selection and assembly of an appropriately cut optical fiber connecting cable requires special knowledge and expertise and is therefore not covered by this operating manual.
!
Before connecting or removing the fiber-optic interface, the supply voltage of the protection device must be switched off.
Connection of the RS 485 interface to other devices is via a 2-pole twisted conductor cable. For further guidelines on connecting the ILSA interface, please see the manual Bus Technology in Integrated Protection and Control Systems for Substations (ILS).

6 Control
All data required for operation of the protection device are entered from the local control panel, and the data important for system management are read out there as well. The local control panel permits the following specific functions: ¨
Readout and modification of settings
¨
Readout of updated measured operating data and state signals as well as stored monitoring signals
¨
Readout and resetting of counters
¨
Resetting of the parallel display (LEDs) and other control functions for testing and startup
¨
Value The value of the information or parameter just selected is displayed.
¨
Address The address of the information or parameter just selected is displayed.
¨
Address Selection: In the normal addressing mode, the two pairs of keys are decoupled from one another and affect the address display. The x coordinate of the address being selected can be set using the left pair of keys, and the y coordinate can be set using the right pair of keys. The respective coordinate can be incremented by pressing the “up” key and decremented by pressing the “down” key.
Control is also possible from the PC interface. In that case the FPC control program is required, along with a special connection cable (see chapter 13 “Accessories and Spare Parts”) and a suitable PC. 6.1 Display and Keyboard The local control panel consists of two 4-digit, 7-segment displays, six function keys and 12 LED indicators.
Changing Parameter Values: Parameter values can only be changed in the input mode, which is signaled by the red LED indicator on the enter key (E). In the input mode the two pairs of “up” and “down” keys are generally coupled and have the same effect on the value display. The system runs through a value range, which is defined separa- tely for each address together with the incrementation (see “Address List” in the appendix). The next higher value is obtained by pressing the “up” key, and the next lower value by pressing the “down” key.

¨ Reset The LED indicators can be reset by pressing the reset key (R). The event records are not affected and remain in the event memories. Other functions of the reset key include deactivation of the input mode (with no further consequences) and keyboard locking. The following diagrams of the individual control steps indicate which specific display can be changed by pressing the “up” or “down” keys. A solid black dot in the upper left corner of the enter key indicates that the red LED indicator is lit up. The addresses used in the examples below are not necessarily valid for the PD 521; they serve to illustrate the principles of local control.
6.3 Change-Enabling Function Although it is possible to select any address and read the associated value by pressing the “up” and “down” keys, it is not possible to switch directly to the input mode. This safeguard prevents unwanted changes in the protective setting. If the protective setting is to be changed, the change-enabling function (address 03 10) must first be activated. The change-enabling function is naturally the only parameter that can be changed when the changeenabling function itself is not activated. Control Step or Description

6.2 Address Selection Addresses are selected by pressing the two pairs of “up” and “down” keys. As long as the keys are being pressed, the value display remains dark. Approximately 1 second after the keys are released the value associated with the selected address will appear in the value display. In principle, any address in the entire address range from 00 00 to 99 99 can be selected. If, however, an address is selected that is not used in the PD 521, the value display will remain dark. The existence of entries in the signal or monitoring signal memories is indicated during operation. This is indicated by the fact that while the “up” and “down” keys are being pressed the value display does not remain dark; instead, the following messages are displayed: ¨
"L..." if there is information in the signal memory
¨
"...E" if there is information in the monitoring signal memory
If “L” and/or “E” still remain in the value display 1 second after the “up” and “down” keys have been released, then there is no information stored for that particular address.

6 Control (continued)
To prevent the change-enabling function from accidentally remaining active after a protective setting has been changed, the enabling function is automatically canceled 100 sec after the last key has been pressed (or once the return time set at address 03 14 has elapsed). The address display immediately jumps to the settable return address (set at address 03 13). The factory-set return address is the address for the change-enabling function. The return time is restarted when any of the six control keys is pressed. Even when the change-enabling function is activated, not all parameters can be changed. For many settings it is also necessary to deactivate the protective function (address 03 30). Such settings include, for example, the configuration parameters by means of which the device interfaces can be adapted to the system. The following entries in the “Change” column of the address list (see Appendix C) indicate whether values can be changed or not:

6.5 Memory Readout
Control Step or Description
Memories can be read out after they are accessed via the appropriate entry address. For this purpose it is not necessary to activate the change-enabling function or even to deactivate the protective function. Accidental clearance of a memory via its entry address is not possible.
Press the enter key (E). The address display changes from 03 00 to 04 20. A period is displayed after each digit in the address. This indicates that a special memory mode is now active. The fault number of the most recent fault (e.g. number 2) appears in the value display for address 04 20. In every fault record the fault number is placed at the beginning of the related fault log for identification purposes. Since for each new fault record the actual value of address 04 20 is increased by the value of "1" in order to count faults, the fault number of the most recent fault also corresponds to the number of recorded faults since the signal memory was last reset. If, after entry into the signal memory, the address 04 20 and the value "0" are indicated, then no fault is stored in the signal memory.

All information memories – particularly the signal and monitoring signal memories – and LED indicators can be reset manually. In addition, the LED indicators are automatically cleared and reset at the start of a new fault so that they always display the last fault. The user can also reset the LED indicators manually by pressing the reset key; this is always possible when the device is in the normal control mode. It always triggers an LED indicator test. The signal memory is not affected by this process so that accidental erasing of the fault record associated with the reset signal pattern is reliably prevented. Because of the signal memory’s ring structure the information in this memory is automatically updated for five consecutive events, so that in principle a manual reset would not be necessary. However, if the signal memory should need to be cleared completely – after function tests, for example – this can be done via the corresponding reset address. Control Step or Description

The PD 521 distance protection device must be adjusted to the system and to the protected equipment by means of appropriate settings. This section gives instructions for determining the proper settings. The address list in the Appendix lists all parameters with their setting ranges and incrementation or selection tables. The Set Value Record Sheets in the Appendix make it possible to keep a complete and well-organized record of all settings. The units are supplied with a factory-set configuration of settings that in most cases correspond to the “default setting” given in the address list. If the factory settings differ from the default settings, then this is indicated below at the appropriate points.
7.1 Device Identification The device identification settings are used to record the ordering information and the design version of the protection device. They have no effect on the protective function. These settings should only be changed if the design version of the protection device is modified. 7.1.1 Ordering Information 00 00

7.2.2 Binary Inputs The PD 521 has two optical coupler inputs for processing binary signals from the system. The connection scheme for the binary inputs is shown in the terminal connection diagrams. The address list gives information about the configuration options for all binary inputs (see Appendix C). When configuring binary inputs it is essential to ensure that the same information cannot be processed by two binary signal inputs. This means that a given function can only be assigned to one binary signal input and not to both. A standard setting that differs from the “default setting” given in the address list has been factory-set. The factory setting is given in the terminal connection diagrams in the Supporting Documents supplied with each device and also in Appendix E of this manual.

The contact data for the all-or-nothing relays permits them to be used either as command relays or as signal relays. One signal can also be assigned to several output relays simultaneously for the purpose of contact multiplication.

Therefore for proper operation of distance protection, the PD 521’s nominal current, 1 A or 5 A, must be entered. Fig. 2 MAIN: Connect. meas. circ. Connection of the measuring voltage circuits determines directional measurement of the distance protection function. If the connection is made as described in Chapter 5, then the “Forward” setting (1) should be selected if the PD 521’s “forward” decision will be in the direction of the outgoing feeder. If the connection direction is reversed or, given the connection direction according to Chapter 5, if the decision for “forward” is to be in the busbar direction, then the setting must be “2.”
MAIN: System frequency The nominal frequency of the network must be set. If the chosen setting is “60“ = 60 Hz, the ground fault direction determination by steady-state values cannot be enabled. Fig. 13 MAIN: Transfer for 1p For single-phase overcurrent starting without ground starting either ground starting or another phase starting needs to be transfertripped. The user may choose to always trip the ground starting function or, depending on current magnitude, ground or phase starting. See the section on “Starting Logic” in Chapter 3 for more information.

After the settings have been made, the following checks should be carried out once again: ¨
Does the function assignment of the binary signal inputs agree with the terminal connection diagram?
¨
Has the correct operating mode been selected for the binary signal inputs?
¨
Does the function assignment of the output relays agree with the terminal connection plan?
¨
Have all settings been made correctly?

Testing By using the signals and displays generated by the PD 521 it is possible to determine whether the PD 521 is correctly set and properly interconnected with the station. Signals are signaled by output relays and LED indicators and entered into the signal memory. In addition, the signals can be checked by selecting the appropriate signal addresses.
Checking the Binary Signal Inputs When the binary signal inputs are configured for the appropriate signals, then it is possible to determine from the signals (see Section 8.2) whether the protection device recognizes the binary signals correctly. ¨
Address 54 00: display of the current state of binary signal input U1
¨
Address 54 03: display of the current state of binary signal input U2
The displayed values have the following meanings: ¨
Value of "0": Not energized.
¨
Value of "1": Energized.
This display appears regardless of the binary signal input mode selected. Checking the Output Relays It is possible to trigger the output relays for a settable time period for test purposes (time setting at address 03 44). First set value „1“ at address 03 12 ( PC/ILSA: T es t m ode USER), then select the output relay to be tested (address 03 42). Test triggering then occurs through address 03 43. It is password-protected (see Chapter 6, Section "Password-Protected Control Operations").
If the circuit breaker will not be operated during testing, the trip command can be blocked through address 21 12 or an appropriately configured binary signal input. If a test of the circuit breaker is desired, it is possible to issue a trip command for 100 ms through address 03 40 or an appropriately configured binary signal input. Selection of the trip command from the integrated local control panel is password-protected (see Section 6.7, "PasswordProtected Control Operations"). If the PD 521 is connected to a control station it is advisable to activate the test mode via address 03 12 or an appropriately configured binary signal input. The messages are then identified accordingly (reason for transmission: test mode).

Checking the Protective Function Checking Distance Protection When checking distance protection with a single-phase test device, the measuring circuit monitoring function should be deactivated (address 14 01) since it would otherwise always operate and thus block distance protection after approximately 10 s. If the signal M A I N : M . c . b . t r i p V L S E X T is assigned to a binary signal input then the latter must have a logic value of "0." Checking the Fault Detection Logic The fault detection settings can be illustrated in a V-I diagram (see Figure 104). The slope of the impedance line plotted in the V-I diagram is a function of the settings for underimpedance fault detection logic and the phase displacement between the measured variables (see Figure 104).
104 Characteristic of underimpedance fault detection logic
When checking underimpedance fault detection logic using single-phase test current we obtain the following relation for the operate condition for a phase-to-phase loop:
V test = 2 × Z< I test V test × e jjtest I test × e j0 °
= 2 × Z < × e j jZ
For absolute value (modulus) and angle this means:

Operation of ground starting is only signaled by the LED indicator if starting in a phase also operates. The operation of ground starting independent of operation of phase starting can be observed at address 36 21.

With a single-phase test current we obtain I neg =
1 ×I 3 test
I P,max = I test For the operate conditions that means: 1 ×I ³ (Ineg > ) × I test 3 test
0.333 ³ (Ineg >) Therefore operation of current measuring circuit monitoring with single-phase test current is only possible if the threshold operate value is set smaller than 0.333.
89521-302/-303-401/-402-602 / AFSV.12.06470 EN

For two-phase test current in phase opposition we obtain:
I neg =
1 1 × I test + a 2 × ( - I test ) = × I test 3 3
IP,max = Itest For the operate condition this means: 1 3
× I test ³ (Ineg >) × I test
0.577 ³ (Ineg> ) Therefore operation of current measuring circuit monitoring with a two-phase test current in phase opposition is only possible if the threshold operate value is set smaller than 0.577. If the threshold operate value satisfies the respective condition, then current measuring circuit monitoring operates with a test current greater than 0.125 Inom after the operate delay of 10.1 s has elapsed. Negative-sequence monitoring of the voltage measuring circuits is enabled if at least one phase-to-ground voltage exceeds the value 0.7 × Vnom / 3 . Other enabling criteria that can be activated on an optional basis are the following (selection of enabling criteria at address 14 07): ¨
A phase current must exceed 0.05 × Inom.
¨
The signal at the binary signal input configured for A R C : C B c l o s e d s i g . E X T must have a logic value of "1."
89521-302/-303-401/-402-602 / AFSV.12.06470 EN
If negative-sequence monitoring has been enabled, the PD 521 determines the absolute value of negativesequence voltage according to the following formula:
V neg =
1 × V A - G + a2 × V B - G + a × V C - G 3
0
a = e j 120 0 a 2 = e j 240 The trigger threshold of Vneg is set permanently at 0.2 × Vnom / 3 . In the case of a single-phase test using
V B - G = V C - G = 0 , the result of that and of the previously cited calculation formula for Vneg is that the trigger operates when the test voltage exceeds the following value:
V test ³ 3 × 0.2 ×
Vnom 3
A signal is not issued until the operate delay totaling 9.8 s has elapsed.

Checking Backup Overcurrent Time Protection
Checking Protective Signaling
The switch to backup overcurrent time protection (BUOC) — if it has been appropriately set — is brought about by measuring circuit monitoring or the tripping of the voltage transformer miniature circuit breaker on the line side.
The protective signaling function can only be checked if protective signaling is ready. This is displayed at address 37 27 (P S I G : R e a d y ).
If the current exceeds the set threshold operate value BUOC: I > , then starting occurs in the corresponding phase(s). After the set time delay B U O C : t I > has elapsed, the PD 521 trips. If M A I N : N e u t r a l p o i n t t r e a t ( m e n t ) is set to "Low-impedance-grounding“, then an SN start occurs if the residual current IN calculated by the PD 521 exceeds the set threshold B U O C : I N > . After the set time delay B U O C : t I N > has elapsed, the PD 521 trips. The PD 521 calculates the residual current IN according to the following formula:
I N = I A + I B + IC From this we obtain in the case of a single-phase test (for example, IB = IC = 0) a test current of
I test = IN > ×Inom at which the operate threshold BUOC: I N > is reached. If the PD 521 is operating with protective signaling or ARC, tripping of the backup overcurrent time protection proceeds after the corresponding tripping times have elapsed.
If protective signaling is not ready, this may be caused by the following reasons: ¨
Protective signaling is not activated. This can be checked at address 15 04 P S I G : E n a b l e d U S E R . (The address is set to "0".)
¨
Protective signaling has been blocked by triggering a correspondingly configured binary signal input (P S I G : B l o c k i n g E X T , address 36 49).
¨
A fault has been detected in the communications channel. (This can be checked at address 36 60.)
If the conditions for testing are satisfied, it is possible to generate a send signal for test purposes from the integrated local control panel (address 15 09) or by triggering a correspondingly configured binary signal input (P S I G : T e s t t e l e c o m . E X T ). This pulse will be present for 500 ms and is extended for the set reset time. If the “with echo" setting has been selected in the protection device at the remote station, then the received signal is returned. The "with echo" setting is only active in the following protective signaling operating modes: ¨
PUTT (permissive underreaching transfer tripping)
¨
Zone extension
¨
Signal comparison release scheme
¨
Signal comparison blocking scheme
The possibility for testing does not exist if P S I G : O p e r a t i n g m o d e has been set for Direct transfer trip underreaching.

Checking Steady-State Ground Fault Direction Determination
If both the ground current and the neutral-point displacement voltage formed from the three phase-toground voltages are available as measured variables, the PD 521 determines the ground fault direction through evaluation of the ground fault using steady-state values. Switching between steady-state power evaluation and steady-state current evaluation is done from the integrated local control panel or by triggering an appropriately configured binary signal input.
Auxiliary Circuit in Resonant-Grounded Systems First the fuse in phase A of the voltage transformer is removed and the associated secondary side is shortcircuited (see Figures 107 and 108). As a result a displacement voltage VN-G is obtained whose magnitude is smaller by a factor of 3 than that of the displacement voltage in the case of a dead fault to ground. If the current is measured in a Holmgreen group then the current transformer in A on the secondary side must be disconnected and short-circuited (see Figure 107).
If allowed by system operation, a ground fault can be closed on the busbar side (BS) or the line side (LS). The PD 521 must then transmit the corresponding signals. However, a requirement is that the set thresholds for ground current (G F D S S : I N , a c t > / I N , r e a c > B S or L S ) and for the neutral-point displacement voltage (G F D S S : V N - G > ) are exceeded. Because of the danger of a double ground fault, a function test involving the closing of a ground fault will not be possible in most cases. In these cases the current and voltage transformers in the system can be connected so that a function test is possible without a ground fault. The ground current measured by the PD 521 and the neutral-point displacement voltage are displayed as operating data in primary quantities and referred to the nominal quantities of the protection device (see Appendix C, "Measured Operating Data").

Malfunctioning after Connection to the System: ¨
The 7-segment displays do not light up. n Check to see whether there is supply voltage at the equipment connection points. n Check to see whether the magnitude of the auxiliary voltage is correct. The PD 521 is protected against damage resulting from polarity reversal.
!
Turn off the power supply voltage before carrying out further checks. Components behind the front panel are energized.
n Check to see whether the ribbon cable between input-output module and processor board is plugged in. (To do so, remove the front panel.)
!
Where possible, disconnection of the ribbon cable between the processor module and the I/O module should be avoided. Should disconnection have occurred, however, then the device needs to be re-initialized by way of a cold restart.
n Check to see whether fuse F1 (type M1C) on the lower printed circuit board (I/O module) is OK. If the fuse is defective it should not be replaced without first determining the cause of failure. If a fuse is replaced without eliminating the problem, there is danger that the damage will spread. ¨
The protection device signals “Warning” (LED H1). Identify the specific problem by reading out the monitoring signal memory (see 6.5.2 “Monitoring Signal Memory Readout”).

11 Maintenance
The PD 521 is a low-maintenance device. The components used in the units are selected so that they meet exacting requirements. Recalibration is not necessary. The PD 521 is equipped with a lithium battery for nonvolatile storage of event data and for continued operation of the internal clock in the event of a failure of auxiliary voltage. Loss of capacity due to module-internal selfdischarging amounts to less than 1% per year over a period of availability of 10 years. Since the terminal voltage remains virtually constant until capacity is exhausted, usefulness is maintained until a very low residual capacity is reached. Given a nominal capacity of 800 mAh and discharge currents of only a few mA during device storage and/or in the range of the self-discharge current during device operation, a correspondingly long service life results. It is therefore recommended that the lithium battery only be replaced after a period of about ten years. The lithium battery can be replaced without soldering. Maintenance work may only be carried out by trained personnel with the auxiliary voltage turned off. The lithium battery is located on the input-output module.
Components located behind the front panel are energized. Turn off the power supply voltage before opening the unit.
!
After loosening four bolts on the front side of the front panel, the local control module (front panel and processor module) can be removed once the following plugs have been removed first: ¨ The tab connector on the case ¨ The tab connector on the lower circuit board (I/O module) ¨ The ribbon cable connecting the local control module (front panel and processor module) with the I/O module ¨ The ribbon cable connecting the local control module with the optional ILSA interface (-X7 and -X8 or -X9) Check the position of the connector. Do not allow the connecting cable to kink.
!
Where possible, disconnection of the ribbon cable between the processor module and the I/O module should be avoided. Should disconnection have occurred, however, then the device needs to be re-initialized by way of a cold restart.
The PD 521 is used as a safety device and must therefore be routinely checked for proper operation. It is recommended that the first functional test be carried out after about 6 to 12 months. Additional functional tests should be carried out at intervals of about 2 to 3 years – 4 years at the maximum. Routine Functional Testing The PD 521 digital protection device incorporates in its system a very extensive self-monitoring function for hardware and software. The internal structure guarantees, for example, that communication within the processor system will be checked on a continuing basis. Nonetheless, there are a number of subfunctions that cannot be checked by the self-monitoring feature without running a test from the device terminals. The respective device-specific properties and setting parameters must be observed in such cases. In particular, none of the control and signaling circuits run to the device from the outside are checked by the selfmonitoring function.

11 Maintenance (continued)
Analog Input Circuits Within the PD 521 an analog-digital converter is used to convert analog measured variables. However, an instrument transformer, filter, analog multiplexer and 1/16 amplifier are also incorporated in each single measuring channel so that a test from the device terminals is required in order to verify proper functioning. The supply voltages are monitored continuously. In conjunction with self-monitoring, moreover, the measuring circuit monitoring feature integrated into the protection function can in many cases exhibit a higher sensitivity and thus detect additional deviations, depending on the parameter assignment. A static test of the analog input circuits is best carried out by operating data measurement of the primary measured operating data or by using a suitable testing device. A “small” measured value (in the current path the nominal current, for example) and a “large” measured value (in the voltage circuit the nominal voltage, for example) should be used to check the effective range of the A/D converter. In this way the total modulation range is checked, including gain change-overs. The gain change-over occurs at a modulation of 1/16 of full scale. In the distance protection function this would be at approximately 6 × Inom in the current path where full modulation is 100 × Inom , and in the voltage path it would be at approximately 6 V phase-toground voltage at the device terminals.
This dynamic test is not absolutely necessary since it only checks the stability of a very few passive components. On the basis of reliability analysis one can expect statistically that in 10 years in 1000 devices only one component will be outside the tolerance zone. Additional testing in the analog area, such as for the impedance or starting characteristics, is not necessary in our opinion since complete digital processing of this information is carried out on the basis of the measured analog current and voltage values. Proper operation will have been demonstrated in conjunction with the type test. The function ‘ground fault direction determination using steady-state values’ can be checked in a similar way, that is by means of operating data measurement and a test device.
A check of the change-over point of gain change-over is hardly possible since the latter is determined by the hardware configuration. The only indication lies in a change in the measurement resolution. In the current path we obtain quantization levels of approximately 0.006 × Inom in the lower range and 0.1 × Inom in the upper range.

Description Components of a symbol A symbol consists of a contour or contour combination and one or more qualifiers.
To document the linking of analog and binary signals, additional symbols have been used, taken from several DIN documents. As a rule, direction of the signal flow is from left to right and from top to bottom. Other flow directions are marked by an arrow. Input signals are listed on the left side of the signal flow, output signals on the right side.

To obtain more space for representing a group of related elements, contours of the elements may be joined or cascaded if the following rules are met:
Control block A control block contains an input function common to several symbols. It is used for the collective setting of several trigger elements, for example.
Output block An output block contains an output function common to several symbols.
There is no functional linkage between elements whose common contour line is oriented in the signal flow direction. Note: This rule does not necessarily apply to configurations with two or more signal flow directions, such as for symbols with a control block and an output block. There exists at least one logical link between elements whose common contour line runs perpendicularly to the signal flow direction.

The number in the symbol may be replaced by any other number if the number of inputs is increased or decreased accordingly. Delay element The transition from value 0 to 1 at the output occurs after a time delay of t1 relative to the corresponding transition at the input. The transition from value 1 to 0 at the output occurs after a time delay of t2 relative to the corresponding transition at the input. t1 and t2 may be replaced by the actual delay values (in seconds or strobe ticks). Monostable flip-flop The output variable will be 1 only if the input variable changes to 1. The output variable will remain 1 for 100 ms, independent of the duration of the input value 1 (non-retriggerable). Without a 1 in the function block the monostable flip-flop is retriggerable. The time is 100 ms in this example, but it may be changed to any other duration.
