Product description The voltage regulator serves to keep constant the output voltage of a transformer with an on-load tap-changer. To do this, the voltage regulator compares the transformer's measured output voltage (Vactual) with a defined reference voltage (Vreference). The difference between Vactual and Vdesired is the control deviation (dV). If the control deviation is greater than the specified bandwidth (B%), the voltage regulator emits a switching pulse after a defined delay time T1. The switching pulse triggers an on-load tap-changer tap change which corrects the transformer's output voltage. The voltage regulator parameters can be optimally adjusted to the line voltage behavior to achieve a balanced control response with a small number of on-load tap-changer operations. The following diagram (on page 20) shows an overview of voltage regulation.

3.6.1
Operating concept The voltage regulator's operating panel is split into an operation control level and a level for parameterization and configuration. The keys for operating the device are completely separate from those used for parameterization. At the operation control level, key activation is signaled visually by means of LEDs. The LEDs integrated in the RAISE/LOWER keys are illuminated during the entire tap change operation of the on-load tap-changer if "motor running" is signaled at the status input. This signal must have previously been parameterized. This visual monitoring option simplifies operation of the voltage regulator. The voltage regulator is equipped with a key lock to protect against unintentional operation. To activate or deactivate, press the ESC and F5 keys simultaneously.

Description of key functions
Key
Symbol RAISE
Function In manual mode the motor-drive unit can be operated directly using the RAISE key. When RAISE is used, the motor-drive unit changes the on-load tap-changer and therefore the step voltage. In manual mode the motor-drive unit can be operated directly using the LOWER key. When LOWER is used, the motor-drive unit changes the on-load tap-changer and therefore the step voltage. Key without function. "Remote" operating mode is enabled or disabled via input IO-X1:31.
LOWER
REMOTE MANUAL
Manual mode. For manual control of the motor-drive unit and parameterization of the voltage regulator. Auto mode. Voltage is controlled automatically.

4.1
Packaging
4.1.1
Purpose The packaging is designed to protect the packaged goods both during transport and for loading and unloading as well as during periods of storage in such a way that no (detrimental) changes occur. The packaging must protect the goods against permitted transport stresses such as vibration, knocks and moisture (rain, snow, condensation). The packaging also prevents undesired position changes of the packaged goods within the packaging during storage. The packaged goods must be prepared for shipment before actually being packed so that the goods can be transported safely, economically and in accordance with regulations.
4.1.2
Suitability, structure and production The goods are packaged in a sturdy cardboard box. This ensures that the shipment remains in the intended transport position and that none of its components touches the load surface during transport or the floor after it is unloaded. The box is designed for a maximum load of 10 kg. Inlays inside the box stabilize the goods, preventing impermissible changes of position, and protect them from vibration.

Transportation, receipt and handling of shipments In addition to oscillation and shock stress, jolts must also be expected during transportation. In order to prevent possible damage, avoid dropping, tipping, knocking over and colliding with the product. If a crate falls from a particular height (e.g. when slings tear) or experiences an unbroken fall, damage must be expected regardless of the weight. Before acceptance, all deliveries must be checked by the recipient (acknowledgement of receipt) for the following:
Completeness based on the delivery slip
External damage of any type.
The checks must take place after unloading when the crate can be accessed from all sides. If external transport damage is detected on receipt of the shipment, proceed as follows:
50
Immediately record the transport damage found in the shipping documents and have this countersigned by the carrier.
In the event of severe damage, total loss or high damage costs, immediately notify the sales department at Maschinenfabrik Reinhausen and the relevant insurance company.

4 Packaging, Transport and Storage
After identifying the damage do not modify the condition of the shipment further and also retain the packaging material, until an inspection decision has been made by the transport company or the insurance company.
Record the details of the damage immediately together with the carrier involved. This is essential for any claim for damages!
If possible, photograph damage to packaging and packaged goods. This also applies to signs of corrosion on the packaged goods due to moisture inside the packaging (rain, snow, condensation).
Name the damaged parts.
When damages are hidden, i.e. damages which are not determined until unpacking after the receipt of the shipment, proceed as follows:
Make the party responsible for the damage liable as soon as possible by telephone and in writing, and prepare a damage report.
Observe, in this regard, the time periods applicable to such actions in the respective country. Inquire about these in good time.
With hidden damage, it is very hard to make the transportation company (or other responsible party) liable. Any insurance claims for such damages can only be successful if relevant provisions are expressly included in the insurance terms and conditions.
4.3
Storage of shipments Selection and arrangement of the storage location should meet the following requirements:
Stored goods are protected against moisture (flooding, water from melting snow and ice), dirt, pests such as rats, mice, termites and so on, and against unauthorized access.
Store the box on timber beams and planks as a protection against rising damp and for better ventilation.
Carrying capacity of the ground under the goods is sufficient.
Entrance and exit paths are kept free.
Check stored goods at regular intervals. Also take appropriate action after storms, heavy rain or snow and so on.

Unpacking The goods are packaged in a sturdy cardboard box. This ensures that the shipment remains in the intended transport position and that none of its components touches the load surface during transport or the floor after it is unloaded. Inlays inside the box stabilize the goods, preventing impermissible changes of position, and protect them from vibration. Unpack the voltage regulator as follows: 1.
Remove the lid from the lower part of the cardboard box. The upper inlay contains the accessories supplied, the separate box labeled "Documentation" contains the device documents.
2.
Check scope of supply for accessories.
3.
Take the box labeled "Documentation" out of the cardboard box.
4.
Remove the upper inlay from the packaging.
5.
The voltage regulator in the underlying inlay can now be freely accessed.
6.
Remove voltage regulator from the packaging.
The voltage regulator has been unpacked and can be mounted. For mounting, proceed as described in the Mounting section.
5.2
Mounting After unpacking, the voltage regulator can be mounted. The voltage regulator's standardized plug-in housing is intended for fitting in a 19-inch control cabinet. We would recommend a design with a pivoting frame to allow easy access to the connections on the rear of the voltage regulator. The voltage regulator can be mounted in 4 different ways:
Flush panel mounting 19" housing
Flush panel mounting for half 19" housing
Wall mounting for half 19" housing
Wall mounting with terminal strip for half 19" housing

Information about shielding the CAN bus To ensure that the CAN bus operates correctly, the shielding must be connected as detailed for the following variants. Both voltage regulators share the same potential To ensure potential equalization between the voltage regulators, all voltage regulators must be connected to the same potential equalization rail. If the voltage regulators share the same potential, the CAN bus cable's shielding must be connected to both voltage regulators. Both voltage regulators have different potentials If the voltage regulators have different potentials, the CAN bus cable's shielding may only be connected to one voltage regulator. Note that the effectiveness of the shielding is less than if connected to both voltage regulators. NOTE Damage to the voltage regulator If the CAN bus cable's shielding is connected to 2 voltage regulators with different potentials, current may flow over the shielding. This current may damage the communication cards. ► Ensure that the CAN bus cable's shielding is only connected to one voltage regulator if both voltage regulators have different potentials. If neither connection variant is possible, we would recommend using fiber optic cables. Fiber optic cables decouple the voltage regulators and are not sensitive to electromagnetic interferences (surge and burst).

Selecting the control mode The voltage regulator can be commissioned in NORMset mode or manually. Instead of parameterizing the voltage regulator manually, the NORMset mode enables easy and user-friendly commissioning of the voltage regulator with a limited set of parameters. When this mode is selected, the factory settings for voltage regulation are accepted. NOTE Damages to the voltage regulator and system periphery An incorrectly connected voltage regulator can lead to damages in the monitoring system and system periphery. ► Prior to commissioning, be sure to check the entire configuration and the measuring and operating voltage.
We recommend using a registration device to record the transformer voltage (actual value) in order to evaluate how the voltage regulator is functioning.

We recommend a temporary setting of 100 seconds for the delay time T1 when commissioning the transformer. Depending on the operating conditions, you can also specify the delay time following a longer observation period. In this regard, it is useful to register the actual voltage process and the number of tap-change operations per day. If you wish the voltage regulator to exhibit an integral time response, set an integral control response for time delay T1. The greater the control deviation, the shorter the delay time.

Bandwidth The bandwidth is the permitted deviation of the measured voltage from the selected desired value. If the measured voltage is inside the bandwidth, then no control commands are issued to the on-load tap-changer. If the measured voltage deviates from the specified bandwidth, a tap-change command occurs after the set delay time T1. The on-load tap-changer carries out a tap-change in a positive or negative direction. If the level is persistently above or below the bandwidth, the "Function monitoring" alarm message is triggered after 15 minutes. The corresponding relay is also activated. The alarm message is only reset when the measured voltage returns to within the set.

The bandwidth must be selected in such a way that the output voltage of the transformer (Vactual) returns to within the specified tolerance range after the tap change. If too small a bandwidth is defined, the output voltage exceeds the bandwidth selected and the voltage regulator must immediately issue a tap-change command in the opposite direction. If a very large bandwidth is selected, this results in a major control deviation.
Sample calculation The following transformer parameters are used by way of example for determining the recommended bandwidth: Nominal voltage: Step voltage of position 4: Step voltage of position 5:
Vnominal = 11000 V Vstep4 = 11275 V Vstep5 = 11000 V

Setting delay time T1 Delay time T1 delays the issuing of a tap-change command for a defined period. This function prevents unnecessary tap-change operations if the tolerance bandwidth is exited for a short time. If the current measured voltage leaves the bandwidth, delay time T1 starts. This is shown visually in the display by the time bar filling and the remaining time being indicated. If the control deviation is still present after the delay time, a tap-change command is issued. If during the delay time the measured voltage returns to within the bandwidth range, the delay time still running is counted down in seconds starting from the time already expired. The absolute time display disappears from the display. The time bar graph is shown hatched and shrinks steadily. If the measured voltage exceeds the set bandwidth once more whilst the time is not displayed, then the time delay is restarted from the remaining time. The advantage of counting the time back down is that, if the bandwidth is exceeded frequently, the voltage regulator does not start counting again at 0 seconds, but uses the time already elapsed as the starting point for beginning the next delay time.

Setting control response T1 The delay time T1 can be set to linear or integral. With "Linear time" the voltage regulator responds with a constant delay time which is independent of the control deviation. If "Integral time" is set, the delay time decreases depending on the ratio of current control deviation to set bandwidth B, to a minimum of 1 second. The greater the control deviation (ΔV) the shorter the response time. This means that the voltage regulator reacts faster to unexpectedly large voltage changes in the grid. The regulation accuracy therefore increases at the expense of switching frequency (see diagram).

Compensation The quality of the energy supply depends not only on the voltage at the busbar of the supply transformer (measurement value V), but also the voltage directly at the equipment. In some cases the line impedance - of the cables or overhead lines - needs to be taken into account for voltage regulation. A significant (load-dependent) voltage drop can occur in these cables. This voltage drop is dependent on the following factors at the consumer:
Impedance (apparent resistance)
Cable
Electrical current
Phase angle φ
The voltage regulator has two possible ways of balancing a load-related voltage drop between the transformer and the consumer:
Line drop compensation
Z compensation
Comparison between line drop compensation and Z Compensation Line drop compensation (vectorial compensation):
provides more precise compensation of cable voltage drops
requires several parameters
requires full knowledge of the cable data
Z compensation:
can be used with minor changes in the phase angle cos φ
is not dependent on phase angle cos φ
is simple to set
can also be used in meshed grids

Cross-monitoring Cross-monitoring permits the reciprocal monitoring of 2 voltage regulators. The voltage regulator detects potential errors in the following parts and reports them via the standard self-monitoring:
Mains unit
Processor error
No program
Should an error occur, this is signaled via the status contact. The reciprocal cross-monitoring can therefore only be restricted to the following: No measured value and/or measurement card error With voltage regulators which check one another, the measured value of the other voltage regulator is supplied via second measurement inputs. The measured values calculated accordingly for the voltage regulators are obtained via the CAN bus and compared with the original measured values. If the measured values deviate, the "Measured value error" signal is issued via an output relay. The second measurement inputs should be considered separately from the first ones. This allows voltage regulators from different voltage levels to be checked. Checking voltage regulation within definable upper and lower limits A measured voltage is supplied to a voltage regulator via a second measurement input. In addition to this measured value, a separate desired value, a lower limit and an upper limit and a time delay can be set. If one of these limits is exceeded, a signal is issued via an output relay after the set time. If wired accordingly, relay contacts can block the raise/lower pulse to the motor-drive unit. Regulation of individual voltage regulators is not affected by limit value monitoring. In order to ensure communication between the monitoring voltage regulators via the CAN bus interface, the CAN address must be entered. "1" must be assigned as the CAN address for the first voltage regulator and "2" for the second one.

The motor-drive unit supplies the "Motor-drive unit running" signal during the tap-change operation. This signal is present until the tap-change operation is complete. The voltage regulator compares the duration of this signal with the motor runtime set. If the set motor runtime is exceeded, the voltage regulator triggers various actions:

"Motor runtime monitoring" message
2.
Continuous signal via output relay "Motor-drive unit runtime exceeded" (optional)
3.
Impulse signal via output relay "Trigger motor protective switch" (optional)
Wiring and parameterizing control input/output relay If you want to monitor the motor runtime, the voltage regulator and motor-drive unit must be connected and parameterized as shown below.

7.4.3
Parallel operation Mains power supply sometimes requires an increase in the short-circuit capacity or the throughput capacity at a site. For this reason, tapped transformers are connected in parallel. A safer and more cost effective parallel operation is achieved if the joint capacity of the transformers connected in parallel is utilized without overloading individual transformers. Compliance with the following general conditions is recommended for operating transformers in parallel: Identical rated voltage Ratio of transformer output ( Configuration > Parallel operation. Parallel operation method.
2. Press or to Deactivate the parallel operation method by selecting "Off". 3. Press
.
The parallel operation method is deactivated. 7.4.3.3
Selecting circulating reactive current sensitivity When circulating reactive current is selected, then parallel operation is carried out using the circulating reactive current minimization method. The circulating reactive current is calculated from the transformer currents and their phase angles. A voltage proportional to the circulating reactive current is added to the independently operating voltage regulators as a correction for the measurement voltage. This voltage correction can be reduced or increased using the circulating reactive current sensitivity setting. The circulating reactive current sensitivity method is suited to transformers connected in parallel with a similar nominal output and nominal voltage VK and to vector groups with the same and different step voltages. This does not require any information about the tap position. This parallel operation method requires each transformer in the parallel vector group to be controlled by a separate voltage regulator.
When setting the "circulating reactive current" parallel operation method, the values for blocking and circulating reactive current sensitivity must first be set.

7.4.3.4
Defining the master tap synchronization method With this parallel operation method the voltage regulator is designated as the master. This voltage regulator takes control while all other follower voltage regulators comply with the control commands of the master. The master compares the tap positions of the followers with its own tap position using the CAN bus. If there is a tap difference, the master directs the followers to be adjusted to the same tap position. If the specified master fails, then the error message "Parallel operation error: no master available" appears in the display. In addition, depending on the configuration of the "Simplex mode blocking" parameter, those voltage regulators which are set accordingly are blocked or continue in simplex mode.
Please note that each voltage regulator must be assigned an address using the "CAN Address" display. Each address may only be used once. Only when all voltage regulators are registered can they communicate with one another using the CAN bus and use the "master/follower" method.

7.4.3.6
Specifying the follower tap synchronization method With this parallel operation method, the voltage regulator with the lowest CAN address within the same parallel operation group is automatically selected as master. This voltage regulator undertakes the measurement and adjusts the on-load tap-changer in order to correct the voltage if a deviation occurs. As with the "Master" parallel operation method, the voltage regulator compares the tap position of the followers with its own tap position using the CAN bus. If there is a tap difference, the voltage regulator directs the followers to be adjusted to the same tap position. If there is a tap position difference between the master and follower which is larger than the maximum set tap difference , then the "Parallel operation error" signal is issued. Automatic regulation blocks. Please note that each voltage regulator must be assigned an address using the "CAN Address" display. Each address may only be used once. Only when all voltage regulators are registered can they communicate with one another using the CAN bus and use the "master/follower" method.
To specify the "Automatic tap synchronization" parallel operation method, proceed as follows: 1.

2. Press or repeatedly until "Auto synchronization" appears in the display. 3. Press

Specifying circulating reactive current sensitivity The sensitivity of the circulating reactive current is a measure of its effect on the behavior of the voltage regulator. A setting of 0% has no effect. With circulating reactive current relating to the rated current on the current transformer, if you set the value to 10 % for example, this would cause the voltage in the voltage regulator to be corrected by 10%. This correction to the voltage can be increased or decreased with this setting to attain the optimum value. As soon as you change the circulating reactive current sensitivity value, the value for the result changes in the help text in the display.

If, during parallel operation, the circulating reactive current exceeds the set limit value, then the following event is activated.
"Problem with parallel operation"
As a result, all voltage regulators operating in parallel are blocked. Depending on the set delay time, the "Parallel operation fault" signaling relay is activated (UC-X1/1 and UC-X1/2 signaling relay contact). The corresponding LED lights up.

Should a scenario arise where the follower switches in the opposite direction to the master's tap change, you will have to change this parameter setting from "Default" to "Swapped".

Average value memory and event memory The measured value plotter is split into the following areas: Average value memory In the average value memory, all measured and calculated values are averaged and saved using the average value intervals you set. You can set the average value intervals in stages between 1 and 40 seconds. You can set the average value interval (see "Setting time difference of average value interval" on page 186). Event memory Data is always saved to the event memory with the highest resolution without first being averaged. You can also determine how much memory space is to be made available exclusively for the event memory (see "Setting size of event memory" on page 187). The memory size is 8MB. The measured value plotter is equipped with event triggering such that an event is triggered depending on the undervoltage and/or overvoltage limit value that you can set. The data recorded here are stored in the measured value memory's event memory. To allow instances where values exceed or fall below the limit values to be better evaluated, the chronological sequence for the measured and calculated values also includes the last 10 seconds before the value exceeds or falls below the limit value. Event is saved for a maximum of 5 minutes. Only the time-based processes for values measured and calculated during the event are stored in the event memory.
If the event memory is full, the oldest values are overwritten by the new values measured. You can access information about the current event memory content via the "Info" menu.

Physical connection The connection to system level takes the form of a network cable via the RJ45 port on the rear of the TAPCON® 260. The speed is automatically set to 10 or 100 Mbit. Before commissioning the TAPCON® 260, the customer/system developer and MR should compare configuration data. On request, MR will send the ICD (Intelligent electronic device Configuration Description) file to the customer/system developer and the compared configuration details are returned as a CID (Configured Intelligent electronic Device) file. The parameters for the TCP/IP address, subnet mask and time server address can also be set later on. This can either be done directly via corresponding screens on the TAPCON® 260 itself or via the "TAPCON®-trol system" visualization software, i.e. on a PC or laptop. The system time for the SID card is set via the SNTP (Simple Network Time Protocol) time server. The product was developed in compliance with the relevant EMC standards. In order to maintain EMC standards, note the descriptions provided in the Electromagnetic compatibility (see "Electromagnetic compatibility" on page 55) chapter.

Undervoltage
Message is displayed if the voltage falls below the set "V" limit value. Parameter setting: (see "Setting the V> overvoltage limit value [%]" on page 101) Message is displayed in the event of overcurrent. Parameter setting: (see "Setting limit value I> overcurrent" on page 103). With tap synchronization: The tap positions of the voltage regulators running in parallel were not the same for longer than the set parallel operation signal delay.

Parameter error
One of the voltage regulators running in parallel is not signaling a valid tap position. Neither of the voltage regulators running in parallel is set as master. One of the voltage regulators running in parallel is using the circulating reactive current method. There is no information about the system topology. With circulating reactive current method: The voltage regulator's circulating reactive current was longer than the set parallel operation signal delay and greater than the set limit value One of the voltage regulators running in parallel is using the tap synchronization method. There is no information about the system topology. There is a signal on at least one of the group inputs, but no other voltage regulator was found in the same group.
