8. Digital fault recorder Te relay is provided with a digital ault recorder (DFR) eaturing up to our analog and 64 binary signal channels. Te analog channels record either the waveorm or the trend o the currents measured. Te analog channels can be set to trigger the recording unction when the measured value alls below or exceeds the set values. Te binary signal channels can be set to start a recording on the rising or the alling edge o the binary signal or both. By deault, the binary channels are set to record external or internal relay signals, e.g. the pickup or trip signals o the relay stages, or external blocking or control signals. Binary relay signals such as a protection pickup or trip signal, or an external relay control signal over a binary input can be set to trigger the recording. With the V option, phase and ground voltage waveorms would be available or inclusion in each digital recording.
9. Events recorder Te IED includes a sequence o events recorder (SER) that logs important event activity. Te relay has the capacity to store in non-volatile memory the most recent 1024 events in a rst-in-rst-out (FIFO) bufer with each event date and time stamped to 1 ms resolution. Te event log acilitates detailed pre- and post-ault analyses o eeder aults and disturbances. Te SER inormation can be accessed locally via the user interace on the relay ront panel or remotely via the communication interace o the relay. Te inormation can urther be accessed, either locally or remotely, using the web-browser based user interace.

Each record includes the current values, the Pickup times o the protection blocks, time stamp, etc. Te ault recording can be triggered by the pickup signal or the trip signal o a protection block, or by both. Te available measurement modes include DF, RMS and peak-to-peak. All 128 ault records are retrievable and viewable via all protocols, the local HMI, web-based HMI and user tool PCM600. Demand and minimum and maximum demand currents, watts and vars with date and time stamp are stored as separate recorded data. Te power demand values include single-phase and three-phase quantities with wye- connected Vs and three-phase quantities with delta-connected Vs. Additionally, or congurations A, C and D, a Load Prole eature is included standard. Tis eature records demand currents, watts and vars and bus voltage quantities, depending on the specic conguration, that present a clear view o bus stability and eeder loading. Such load prole is quite useul or system planners. Te Load Prole data recording rate is set by the demand time interval setting and stored in non-volatile memory. For a demand time interval o 15 minutes, approximately 40 days o data is recordable in a rst-in rst-out (FIFO) bufer. Te prole data is retrievable via the relay user tool PCM600 and viewable through its COMRADE viewing tool Wavewin.
11. Circuit-breaker condition monitoring For continuous knowledge o the operational availability o the REF615 eatures, a comprehensive set o monitoring unctions to supervise the relay health, the trip circuit and the circuit breaker health is included. Te breaker monitoring can include checking the wear and tear o the circuit breaker, the spring charging time o the breaker operating mechanism and the gas pressure o the breaker chambers. Te relay also monitors the breaker travel time and the number o circuit breaker (CB) operations to provide basic inormation or scheduling CB maintenance. For standard congurations “B” and “E”, there is a condition monitoring eature or each o the two breakers supported.
12. Trip-circuit monitoring Te trip-circuit monitoring continuously supervises the availability and operability o the trip circuit. It provides open-circuit monitoring both when the circuit breaker is in its closed and in its open position. It also detects loss o circuit-breaker control voltage. Local and remote indication are programmable to ensure immediate notication so the necessary steps can be established to correct beore the next ault e vent occurs.
13. Self-diagnostics Te relay’s built-in sel-diagnostics system continuously monitors the state o the relay hardware and the operation o the relay soware. Any ault or malunction detected will be used or alerting the operator. A permanent relay ault will block the protection unctions o the relay to prevent incorrect relay operation.

14. Fuse failure protection Depending on the chosen standard conguration, the IED includes use ailure supervision unctionality. Te use ailure supervision detects ailures between the voltage measurement circuit and the IED. Te ailures are detected by the negative sequence based algorithm or by the delta voltage and delta current algorithm. Upon the detection o a ailure the use ailure supervision unction activates an alarm and blocks voltage-dependent protection unctions rom unintended operation.
15. Current circuit supervision Depending on the chosen standard conguration, the IED includes current circuit supervision. Current circuit supervision is used or detecting an open in the current transormer secondary circuits. On detecting an opening circuit, the current circuit supervision unction activates an alarm LED and blocks certain protection unctions to avoid unintended operation. Te current circuit supervision unction calculates the sum o the phase currents rom the protection cores and compares the sum with the measured single reerence current rom a core balance current transormer or rom separate cores in the phase current transormers.
17. Power quality Te ability to monitor and detect current and voltage harmonics and short duration system disturbances with the REF615 is possible through the optional power quality (P) unction. Tis unction enables studying system quality conditions, documenting cases and implementing new procedures to improve reliability o service. Te P unctions include these eatures per the IEEE 1159 standard: • • •

19. Cable fault detection 21. Inputs and outputs (CFD) Te REF615 ofers an option eeder cable ault detection (CFD) unction that is able to real-time detect extremely short duration overhead and underground aults in eeders. Tis dedicated unction is programmable to monitor and detect sel-clearing and use-cleared aults. Tese short duration aults are typically undetectable by conventional protection where there is no operation o their substation breaker or eeder recloser. Where dispatchers gain knowledge o these events rom customer calls, this real-time detection provides immediate indication to the dispatcher prior to the rst customer call. Overall outage restoration times may be reduced having knowledge o such eeder event as soon as they happen improving a utility’s reliability metrics.
Te availability o current (ct) and voltage (vt) analog inputs depends upon the standard conguration ordered. Standard and optional binary inputs and outputs (I/O) also depend upon the selected IED conguration. able 4 details the analog inputs and I/O available or each conguration and analog inputs order code characters. Te phase-current inputs are user programmable or 5 A or 1 A ct secondary nominal rating.

22. Communications Te relay (IED) supports a range o communication protocols including IEC 61850, Modbus® and DNP3.0 Level 2. Operational inormation and controls are available through these protocols. Certain communication unctionality, e.g., horizontal communication between relays, is only enabled by the IEC 61850 communication protocol. Te IEC 61850 communication implementation sup ports all monitoring and control unctions. Additionally, parameter settings, disturbance recordings and ault records can be accessed using the IEC 61850 protocol. Disturbance recordings are available to any Ethernet-based application in the standard COMRADE le ormat. Te IED sup ports simultaneous event reporting to ve diferent clients on the communication network bus. Te IED can send binary signals to other IEDs (so cal led horizontal communication) using the IEC 61850-8-1 GOOSE (Generic Object Oriented Substation Event) prole. Binary GOOSE messaging can, e.g., be employed or protection and interlocking-based protection schemes. Te relay meets the GOOSE perormance requirements or tripping applications in distribution substations, as dened by the IEC 61850 standard. Also, the IED supports the sending and receiving o analog values using GOOSE messaging. Analog GOOSE messaging enables ast transer o analog measurement values over the network bus, thus acilitating, or example, sharing o RD input values, such as surrounding temperature values, to other IED applications. Te IED ofers an optional second Ethernet bus to enable the creation o a sel-healing Ethernet ring topology. Te IED communication module options include both galvanic and ber-optic Ethernet combinations. Te communication module including one ber-optic LC port and two galvanic RJ-45 ports is used when the ring between the IEDs is built using CA5 SP cables. Te LC port can in this case be used or connecting the IED to communication ports outside the switchgear. Te communication module including three RJ-45 ports is used when the whole substation network bus is based on CA5 SP cabling. Te sel-healing Ethernet ring solution enables a cost-efective communication ring solution controlled by a managed switch with rapid spanning tree protocol (RSP) support to be created. Te managed switch controls the consistency o the loop, routes the data and corrects the data ow in case o a communication disturbance. Te IEDs in the ring topology act as unmanaged switches orwarding ABB
unrelated data tra c. Te Ethernet ring solution supports the connection o up to 30 ABB 615 series relays. I more than 30 IEDs are to be connected, it is recommended that the network is split into several rings with no more than 30 IEDs per ring. Te sel-healing Ethernet ring solution avoids single point o ailure concerns and improves the reliability o the communication. Te solution can be applied or the Ethernet-based IEC 61850, Modbus and DNP3.0 Level 2 protocols. All communication connectors, except or the ront port connector, are placed on integrated optional communication modules. Te IED can be connected to Ethernet-based communication systems via the RJ-45 connector (100BaseX) or the ber-optic LC connector (100Base-FX). I connection to a serial bus is required, the 10-pin RS-485 screw-terminal or the ber-optic S connector can be used. Modbus implementation supports RU, ASCII and CP modes. Besides standard Modbus unctionality, the IED supports retrieval o time-stamped events, changing the active setting group and uploading o the latest ault records. I a Modbus CP connection is used, ve clients can be connected to the IED simultaneously. Further, Modbus serial and Modbus CP can be used in parallel, and i required both IEC 61850 and Modbus protocols can b e run simultaneously. DNP3.0 Level 2 supports both serial and CP modes or connection to one master. Additionally, changing o the active setting group is supported. When the IED uses the RS-485 bus or the serial communication, both two- and our wire connections are supported. ermination and pull-up/down resistors can be congured with jumpers on the communication card so external resistors are not needed. Te IED supports the ollowing time synchronization methods with a time-stamping resolution o 1 ms: Ethernet-based: • SNP (Simple Network ime Protocol) – primary and secondary SNP servers supported With special time synchronization wiring: • IRIG-B (Inter-Range Instrumentation Group - ime Code Format B) In addition, the IED supports time synchronization via the ollowing serial communication protocols: • Modbus • DNP3.0 Level 2 21
