Section 2 RED615 overview

2.1 Overview

RED615 is a phase-segregated two-end line differential protection and control relaydesigned for utility and industrial power systems, including radial, looped and mesheddistribution networks with or without distributed power generation. RED615 is alsodesigned for the protection of line differential applications with a transformer withinthe protection zone. RED615 relays communicate between substations over a fiberoptic link or a galvanic pilot wire connection. RED615 is a member of ABB’s Relion®

product family and part of its 615 protection and control product series. The 615 seriesrelays are characterized by their compactness and withdrawable-unit design. Re-engineered from the ground up, the 615 series has been guided by the IEC 61850standard for communication and interoperability of substation automation equipment.

The relay provides unit type main protection for overhead lines and cable feeders indistribution networks. The relay also features current-based protection functions forremote back-up for down-stream protection relays and local back-up for the linedifferential main protection. Further, standard configurations B and C also includeearth-fault protection. Standard configurations D and E include directionalovercurrent and voltage based protection functions.

The relay is adapted for the protection of overhead line and cable feeders in isolatedneutral, resistance earthed, compensated (impedance earthed) and solidly earthednetworks. Once the relay has been given the application-specific settings, it candirectly be put into service.

The 615 series relays support a range of communication protocols including IEC61850 with Edition 2 support, process bus according to IEC 61850-9-2 LE, IEC60870-5-103, Modbus® and DNP3. Profibus DPV1 communication protocol issupported by using the protocol converter SPA-ZC 302.

2.5 Web HMI

The WHMI allows secure access to the protection relay via a Web browser. When theSecure Communication parameter in the protection relay is activated, the Web serveris forced to take a secured (HTTPS) connection to WHMI using TLS encryption.TheWHMI is verified with Internet Explorer 8.0, 9.0, 10.0 and 11.0.

WHMI is disabled by default.

WHMI offers several functions.



• Programmable LEDs and event lists• System supervision• Parameter settings• Measurement display• Disturbance records• Fault records• Load profile record• Phasor diagram• Single-line diagram• Importing/Exporting parameters• Report summary

The menu tree structure on the WHMI is almost identical to the one on the LHMI.

The WHMI can be accessed locally and remotely.

• Locally by connecting the laptop to the protection relay via the frontcommunication port.

• Remotely over LAN/WAN.



2.6 Authorization

Four user categories have been predefined for the LHMI and the WHMI, each withdifferent rights and default passwords.

The default passwords in the protection relay delivered from the factory can bechanged with Administrator user rights.

User authorization is disabled by default for LHMI but WHMI alwaysuses authorization.

2.6.1 Audit trail

The protection relay offers a large set of event-logging functions. Critical system andprotection relay security-related events are logged to a separate nonvolatile audit trailfor the administrator.

Audit trail is a chronological record of system activities that allows the reconstructionand examination of the sequence of system and security-related events and changes inthe protection relay. Both audit trail events and process related events can beexamined and analyzed in a consistent method with the help of Event List in LHMIand WHMI and Event Viewer in PCM600.



The protection relay stores 2048 audit trail events to the nonvolatile audit trail.Additionally, 1024 process events are stored in a nonvolatile event list. Both the audittrail and event list work according to the FIFO principle. Nonvolatile memory is basedon a memory type which does not need battery backup nor regular component changeto maintain the memory storage.

Audit trail events related to user authorization (login, logout, violation remote andviolation local) are defined according to the selected set of requirements from IEEE1686. The logging is based on predefined user names or user categories. The user audittrail events are accessible with IEC 61850-8-1, PCM600, LHMI and WHMI.

PCM600 Event Viewer can be used to view the audit trail events and process relatedevents. Audit trail events are visible through dedicated Security events view. Sinceonly the administrator has the right to read audit trail, authorization must be used in



PCM600. The audit trail cannot be reset, but PCM600 Event Viewer can filter data.Audit trail events can be configured to be visible also in LHMI/WHMI Event listtogether with process related events.

To expose the audit trail events through Event list, define theAuthority logging level parameter via Configuration/Authorization/Security. This exposes audit trail events to all users.

2.7 Communication

The protection relay supports a range of communication protocols including IEC61850, IEC 61850-9-2 LE, IEC 60870-5-103, Modbus® and DNP3. Profibus DPV1



communication protocol is supported by using the protocol converter SPA-ZC 302.Operational information and controls are available through these protocols. However,some communication functionality, for example, horizontal communication betweenthe protection relays, is only enabled by the IEC 61850 communication protocol.

The IEC 61850 communication implementation supports all monitoring and controlfunctions. Additionally, parameter settings, disturbance recordings and fault recordscan be accessed using the IEC 61850 protocol. Disturbance recordings are availableto any Ethernet-based application in the IEC 60255-24 standard COMTRADE fileformat. The protection relay can send and receive binary signals from other devices(so-called horizontal communication) using the IEC 61850-8-1 GOOSE profile,where the highest performance class with a total transmission time of 3 ms issupported. Furthermore, the protection relay supports sending and receiving of analogvalues using GOOSE messaging. The protection relay meets the GOOSEperformance requirements for tripping applications in distribution substations, asdefined by the IEC 61850 standard.

The protection relay can support five simultaneous clients. If PCM600 reserves oneclient connection, only four client connections are left, for example, for IEC 61850and Modbus.

All communication connectors, except for the front port connector, are placed onintegrated optional communication modules. The protection relay can be connected toEthernet-based communication systems via the RJ-45 connector (100Base-TX) or thefiber-optic LC connector (100Base-FX). An optional serial interface is available forRS-232/RS-485 communication.

2.7.1 Self-healing Ethernet ring

For the correct operation of self-healing loop topology, it is essential that the externalswitches in the network support the RSTP protocol and that it is enabled in theswitches. Otherwise, connecting the loop topology can cause problems to thenetwork. The protection relay itself does not support link-down detection or RSTP.The ring recovery process is based on the aging of the MAC addresses, and the link-up/link-down events can cause temporary breaks in communication. For a betterperformance of the self-healing loop, it is recommended that the external switchfurthest from the protection relay loop is assigned as the root switch (bridge priority= 0) and the bridge priority increases towards the protection relay loop. The end linksof the protection relay loop can be attached to the same external switch or to twoadjacent external switches. A self-healing Ethernet ring requires a communicationmodule with at least two Ethernet interfaces for all protection relays.

Figure 6: Self-healing Ethernet ring solution

The Ethernet ring solution supports the connection of up to 30protection relays. If more than 30 protection relays are to beconnected, it is recommended that the network is split into severalrings with no more than 30 protection relays per ring. Each protectionrelay has a 50-μs store-and-forward delay, and to fulfil theperformance requirements for fast horizontal communication, thering size is limited to 30 protection relays.

2.7.2 Ethernet redundancy

IEC 61850 specifies a network redundancy scheme that improves the systemavailability for substation communication. It is based on two complementaryprotocols defined in the IEC 62439-3:2012 standard: parallel redundancy protocolPRP and high-availability seamless redundancy HSR protocol. Both protocols rely onthe duplication of all transmitted information via two Ethernet ports for one logicalnetwork connection. Therefore, both are able to overcome the failure of a link orswitch with a zero-switchover time, thus fulfilling the stringent real-timerequirements for the substation automation horizontal communication and timesynchronization.

PRP specifies that each device is connected in parallel to two local area networks.HSR applies the PRP principle to rings and to the rings of rings to achieve cost-effective redundancy. Thus, each device incorporates a switch element that forwardsframes from port to port. The HSR/PRP option is available for all 615 series protectionrelays. However, RED615 supports this option only over fiber optics.



IEC 62439-3:2012 cancels and replaces the first edition published in2010. These standard versions are also referred to as IEC 62439-3Edition 1 and IEC 62439-3 Edition 2. The protection relay supportsIEC 62439-3:2012 and it is not compatible with IEC 62439-3:2010.

PRPEach PRP node, called a double attached node with PRP (DAN), is attached to twoindependent LANs operated in parallel. These parallel networks in PRP are calledLAN A and LAN B. The networks are completely separated to ensure failureindependence, and they can have different topologies. Both networks operate inparallel, thus providing zero-time recovery and continuous checking of redundancy toavoid communication failures. Non-PRP nodes, called single attached nodes (SANs),are either attached to one network only (and can therefore communicate only withDANs and SANs attached to the same network), or are attached through a redundancybox, a device that behaves like a DAN.

SCADACOM600

GUID-334D26B1-C3BD-47B6-BD9D-2301190A5E9D V2 EN

Figure 7: PRP solution

In case a laptop or a PC workstation is connected as a non-PRP node to one of the PRPnetworks, LAN A or LAN B, it is recommended to use a redundancy box device or anEthernet switch with similar functionality between the PRP network and SAN toremove additional PRP information from the Ethernet frames. In some cases, defaultPC workstation adapters are not able to handle the maximum-length Ethernet frameswith the PRP trailer.

There are different alternative ways to connect a laptop or a workstation as SAN to aPRP network.



• Via an external redundancy box (RedBox) or a switch capable of connecting toPRP and normal networks

• By connecting the node directly to LAN A or LAN B as SAN• By connecting the node to the protection relay's interlink port

HSRHSR applies the PRP principle of parallel operation to a single ring, treating the twodirections as two virtual LANs. For each frame sent, a node, DAN, sends two frames,one over each port. Both frames circulate in opposite directions over the ring and eachnode forwards the frames it receives, from one port to the other. When the originatingnode receives a frame sent to itself, it discards that to avoid loops; therefore, no ringprotocol is needed. Individually attached nodes, SANs, such as laptops and printers,must be attached through a “redundancy box” that acts as a ring element. For example,a 615 or 620 series protection relay with HSR support can be used as a redundancybox.

Figure 8: HSR solution

2.7.3 Process bus

Process bus IEC 61850-9-2 defines the transmission of Sampled Measured Valueswithin the substation automation system. International Users Group created aguideline IEC 61850-9-2 LE that defines an application profile of IEC 61850-9-2 tofacilitate implementation and enable interoperability. Process bus is used fordistributing process data from the primary circuit to all process bus compatibledevices in the local network in a real-time manner. The data can then be processed byany protection relay to perform different protection, automation and control functions.



UniGear Digital switchgear concept relies on the process bus together with currentand voltage sensors. The process bus enables several advantages for the UniGearDigital like simplicity with reduced wiring, flexibility with data availability to alldevices, improved diagnostics and longer maintenance cycles.

With process bus the galvanic interpanel wiring for sharing busbar voltage value canbe replaced with Ethernet communication. Transmitting measurement samples overprocess bus brings also higher error detection because the signal transmission isautomatically supervised. Additional contribution to the higher availability is thepossibility to use redundant Ethernet network for transmitting SMV signals.

Figure 9: Process bus application of voltage sharing and synchrocheck

The 615 series supports IEC 61850 process bus with sampled values of analogcurrents and voltages. The measured values are transferred as sampled values usingthe IEC 61850-9-2 LE protocol which uses the same physical Ethernet network as theIEC 61850-8-1 station bus. The intended application for sampled values is sharing themeasured voltages from one 615 series protection relay to other devices with phasevoltage based functions and 9-2 support.

The 615 series protection relays with process bus based applications use IEEE 1588 v2Precision Time Protocol (PTP) according to IEEE C37.238-2011 Power Profile forhigh accuracy time synchronization. With IEEE 1588 v2, the cabling infrastructurerequirement is reduced by allowing time synchronization information to betransported over the same Ethernet network as the data communications.

The process bus option is available for all 615 series protection relays equipped withphase voltage inputs. Another requirement is a communication card with IEEE 1588v2 support (COM0031...COM0037). However, RED615 supports this option onlywith the communication card variant having fiber optic station bus ports. See the IEC61850 engineering guide for detailed system requirements and configuration details.

2.7.4 Secure communication

The protection relay supports secure communication for WHMI and file transferprotocol. If the Secure Communication parameter is activated, protocols require TLSbased encryption method support from the clients. In this case WHMI must beconnected from a Web browser using the HTTPS protocol and in case of file transferthe client must use FTPS.

2.7.5 Protection communication and supervision

The communication between the relays is enabled by means of a dedicated fiber opticcommunication channel. 1310 nm multi-mode or single-mode fibers with LCconnectors are used for line differential communication. The channel is used fortransferring the phase segregated current value data between the relays. The currentphasors from the two relays, geographically located apart from each other, must betime coordinated so that the current differential algorithm can be executed correctly.The so called echo method is used for time synchronization. No external devices suchas GPS clocks are thereby needed for the line differential protection communication.



Apart from the continued protection communication, the communication channel canalso be used for binary signal transfer (BST) that is, transferring of user configurablebinary information between the relays. There are a total of eight BST signals availablefor user definable purposes. The BST signals can originate from the relay’s binaryinputs or internal logics, and be assigned to the remote relay’s binary outputs orinternal logics.

The protection communication supervision continuously monitors the protectioncommunication link. The relay immediately blocks the line differential protectionfunction in case that severe interference in the communication link, risking the correctoperation of the function, is detected. An alarm signal will eventually be issued if theinterference, indicating permanent failure in the protection communication, persists.The two high-set stages of the overcurrent protection are further by default released.

Section 3 RED615 standard configurations

3.1 Standard configurations

RED615 is available with five alternative standard configurations. The standardsignal configuration can be altered by means of the signal matrix or the graphicalapplication functionality of the Protection and Control IED Manager PCM600.Further, the application configuration functionality of PCM600 supports the creationof multi-layer logic functions utilizing various logical elements including timers andflip-flops. By combining protection functions with logic function blocks the relayconfiguration can be adapted to user specific application requirements.

The relay is delivered from the factory with default connections described in thefunctional diagrams for binary inputs, binary outputs, function-to-functionconnections and alarm LEDs. Some of the supported functions in RED615 must beadded with the Application Configuration tool to be available in the Signal Matrix tooland in the relay. The positive measuring direction of directional protection functionsis towards the outgoing feeder.

3.1.1 Addition of control functions for primary devices and the useof binary inputs and outputs

If extra control functions intended for controllable primary devices are added to theconfiguration, additional binary inputs and/or outputs are needed to complement thestandard configuration.

If the number of inputs and/or outputs in a standard configuration is not sufficient, itis possible either to modify the chosen standard configuration in order to release somebinary inputs or binary outputs which have originally been configured for otherpurposes, or to integrate an external input/output module, for example RIO600, to theprotection relay.



The external I/O module’s binary inputs and outputs can be used for the less time-critical binary signals of the application. The integration enables releasing someinitially reserved binary inputs and outputs of the protection relay’s standardconfiguration.

The suitability of the protection relay’s binary outputs which have been selected forprimary device control should be carefully verified, for example make and carry andbreaking capacity. If the requirements for the primary device control circuit are notmet, using external auxiliary relays should be considered.

3.3.3 Functional diagrams

The functional diagrams describe the default input, output, alarm LED and function-to-function connections. The default connections can be viewed and changed withPCM600 according to the application requirements.

The analog channels have fixed connections to the different function blocks inside theprotection relay’s standard configuration. However, the 12 analog channels availablefor the disturbance recorder function are freely selectable as a part of the disturbancerecorder’s parameter settings.

The phase currents to the protection relay are fed from a current transformer. Theresidual current to the protection relay is fed from either residually connected CTs, anexternal core balance CT, neutral CT or calculated internally.

The protection relay offers six different setting groups which can be set based onindividual needs. Each group can be activated or deactivated using the setting groupsettings available in the protection relay or via binary input.

Depending on the communication protocol the required function block needs to beinstantiated in the configuration.

3.3.3.1 Functional diagrams for protection

The functional diagrams describe the IED's protection functionality in detail andaccording to the factory set default connections.

The line differential protection with in-zone power transformer LNPLDF1 is intendedto be the main protection offering exclusive unit protection for the power distributionlines or cables. The stabilized low stage can be blocked if the current transformerfailure is detected. The operate value of the instantaneous high stage can be multipliedby predefined settings, if ENA_MULT_HS input is activated. In this configuration, itis activated by the open status information of the remote-end circuit breaker and earth-switch, and if the disconnector is not in the intermediate position. The intention of thisconnection is to lower the setting value of the instantaneous high stage by multiplyingwith the setting High Op value Mult, in case of internal fault.

Alarm LED3 informs when the line differential is not available possibly due to afailure in protection communication, or if the function is set in a test mode.



Four non-directional overcurrent stages are offered for overcurrent and short-circuitprotection. Three-phase non-directional overcurrent protection PHIPTOC1 can beblocked by energizing the binary input X120:BI1. The instantaneous and first highstage are blocked by activation of line differential protection.

The overcurrent protection and negative-sequence overcurrentprotection are used as backup protection against line differentialprotection.

The backup protection operated information is available at binary output X110:SO2which can be used for external alarm purposes.

The circuit breaker failure protection CCBRBRF1 is initiated via the START input bynumber of different protection functions available in the IED. The circuit breakerfailure protection function offers different operating modes associated with the circuitbreaker position and the measured phase and residual currents.

The circuit breaker failure protection function has two operating outputs: TRRET andTRBU. The TRRET operate output is used for retripping its own breaker throughTRPPTRC2_TRIP. The TRBU output is used to give a backup trip to the breakerfeeding upstream. For this purpose, the TRBU operate output signal is connected to thebinary output X100:PO2.

Binary signal transfer BSTGGIO1 is used for changing any binary information whichcan be used for example, in protection schemes, interlocking and alarms. There areeight separate inputs and corresponding outputs available.

In this configuration, one physical input X110:BI4 is connected to the binary signaltransfer channel one. Local feeder ready and local circuit breaker open information areconnected to the BSTGGIO inputs 6 and 7. These are interlocking information fromcontrol logic. The information of detected current transformer fault is connected toinput 8.

As a consequence of sending interlocking information to remote end, also receiving ofsame information locally is needed. Therefore, remote feeder ready, remote circuitbreaker open and remote current transformer failure are connected to the binary signaltransfer function outputs. Also the remote binary transfer output signal is connected tothe binary output X110:SO3.

Figure 32: Earth-switch 1 control logic

The circuit breaker closing is enabled when the ENA_CLOSE input is activated. Theinput can be activated by the configuration logic, which is a combination of thedisconnector or circuit breaker truck and earth-switch position status, status of the triplogics and remote feeder position indication. Master trip logic, disconnector andearth-switch statuses are local feeder ready information to be sent for the remote end.

The OKPOS output from DCSXSWI defines if the disconnector or circuit breakertruck is either open (in test position) or close (in service position). This output,together with the open earth-switch and non-active trip signals, activates the close-enable signal to the circuit breaker control function block. The open operation for thecircuit breaker is always enabled.

If REMOTE_FEEDER_READY information is missing, forexample, in case of protection communication not connected, itdisables the circuit breaker closing in the local IED.

Line differential protection with in-zone power transformer LNPLDF1 is intended tobe the main protection offering exclusive unit protection for the power distributionlines or cables. The stabilized low stage can be blocked if the current transformerfailure is detected. The operate value of the instantaneous high stage can be multipliedby predefined settings if the ENA_MULT_HS input is activated. In this configuration,the input is activated by the open status information of the remote-end circuit breakerand earth-switch, and if the disconnector is not in the intermediate state. The intentionof this connection is to lower the setting value of the instantaneous high stage bymultiplying with setting High Op value Mult, in case of internal fault.




Four non-directional overcurrent stages are offered for overcurrent and short-circuitprotection. The three-phase non-directional overcurrent protection, instantaneousstage PHIPTOC1 can be blocked by energizing the binary input X120: BI1. Theinstantaneous and first high stage are blocked by activation of line differentialprotection.

Figure 63: Residual voltage protection function

It should be noted that overcurrent protection, negative sequence overcurrentprotection, phase discontinuity, earth-fault protection and residual overvoltageprotections are all used as backup protection against line differential protection. Thebackup protection operated information is available at binary output X110:SO2 whichcan be used for external alarm purpose.

The optional autoreclosing function is configured to be initiated by operate signalsfrom a number of protection stages through the INIT_1...5 inputs. It is possible tocreate individual autoreclose sequences for each input.

The autoreclosing function can be inhibited with the INHIBIT_RECL input. Bydefault, few selected protection function operations are connected to this input. Acontrol command to the circuit breaker, either local or remote, also blocks theautoreclosing function via the CBXCBR1-SELECTED signal.

The circuit breaker availability for the autoreclosing sequence is expressed with theCB_READY input in DARREC1. The signal, and other required signals, are connectedto the CB spring charged binary inputs in this configuration. The open command fromthe autorecloser is connected directly to binary output X100:PO3, whereas closecommand is connected directly to binary output X100:PO1.

Figure 75: Protection communication supervision function

The binary signal transfer function BSTGGIO1 is used for changing any binaryinformation which can be used for example, in protection schemes, interlocking andalarms. There are eight separate inputs and corresponding outputs available.

In this configuration, one physical input X110:BI2 is connected to the binary signaltransfer channel one. Local feeder ready and local circuit breaker open information areconnected to the BSTGGIO1 inputs 6 and 7. These are interlocking information fromcontrol logic. The information of detected current transformer fault is connected to theinput 8.



As a consequence of sending interlocking information to remote end, also receiving ofsame information locally is needed. Therefore, remote feeder ready, remote circuitbreaker open and remote current transformer failure are connected to the binary signaltransfer function outputs. Also the remote binary transfer output signal is connected tothe binary output X110:SO3.

Line differential protection with in-zone power transformer LNPLDF1 is intended tobe the main protection offering exclusive unit protection for the power distributionlines or cables. The stabilized low stage can be blocked if the current transformerfailure is detected. The operate value of the instantaneous high stage can be multipliedby predefined settings if the ENA_MULT_HS input is activated. In this configurationit is activated by the open status information of the remote-end circuit breaker andearth switch, and if the disconnector is not in the intermediate state. The intention ofthis connection is to lower the setting value of the instantaneous high stage bymultiplying with setting High Op value Mult, in case of internal fault.


Four non-directional overcurrent stages are offered for overcurrent and short-circuitprotection. Three-phase non-directional overcurrent protection, instantaneous stage,PHIPTOC1 can be blocked by energizing the binary input X120:BI1. Theinstantaneous and first high stages are blocked by activation of line differentialprotection.

The backup protection operated information is available at binary output X110:SO2which can be used for external alarm purpose.

The optional autoreclosing function is configured to be initiated by operate signalsfrom a number of protection stages through the INIT_1...5 inputs. It is possible tocreate individual autoreclosing sequences for each input.


The circuit breaker availability for the autoreclosing sequence is expressed with theCB_READY input in DARREC1. The signal, and other required signals, are connectedto the CB spring charged binary inputs in this configuration. The open command fromthe autorecloser is connected directly to binary output X100:PO3, whereas the closecommand is connected directly to binary output X100:PO1.

The binary signal transfer function BSTGGIO1 is used for changing any binaryinformation which can be used for example, in protection schemes, interlocking andalarms. There are eight separate inputs and corresponding outputs available.

In this configuration, one physical input X110:BI2 is connected to the binary signaltransfer channel one. Local feeder ready and local circuit breaker open information areconnected to the BSTGGIO input 6 and 7. These are interlocking information fromcontrol logic. The information of detected current transformer fault is connected to theinput 8.



As a consequence of sending interlocking information to remote end, also receiving ofsame information locally is needed. Therefore, remote feeder ready, remote circuitbreaker open and remote current transformer failure are connected to the binary signaltransfer function outputs. The remote binary transfer output signal is connected to thebinary output X110:SO3.

These functions are not included inapplication configuration but they can be added based on the system requirements.

3.6 Standard configuration D

3.6.1 Applications

The standard configuration with directional overcurrent and directional earth-faultprotection, phase-voltage and frequency based protection is mainly intended for cablefeeder applications in distribution networks. The standard configuration for linecurrent differential protection includes support for in-zone transformers. Theconfiguration also includes additional options to select earth-fault protection based onadmittance, wattmetric or harmonic principle.

Standard configuration D is not designed for using all the available functionalitycontent in one relay at the same time. Frequency protection functions and thirdinstances of voltage protection functions must be added with the ApplicationConfiguration tool. To ensure the performance of the relay, the user-specificconfiguration load is verified with the Application Configuration tool in PCM600.

The phase voltages to the protection relay are fed from a voltage transformer. Theresidual voltage to the protection relay is fed from either residually connected VTs, anopen delta connected VT or calculated internally.




The functional diagrams describe the IEDs protection functionality in detail andaccording to the factory set default connections.

Line differential protection with in-zone power transformer LNPLDF1 is intended tobe the main protection offering exclusive unit protection for the power distributionlines or cables. The stabilized low stage can be blocked if the current transformerfailure is detected. The operate value of the instantaneous high stage can be multipliedby predefined settings if the ENA_MULT_HS input is activated. In this configuration,it is activated by the open status information of the remote-end circuit breaker andearth switch, and if the disconnector is not in the intermediate state. The intention ofthis connection is to lower the setting value of the instantaneous high stage bymultiplying with setting High Op value Mult, in case of internal fault.

The binary signal transfer function BSTGGIO is used for changing any binaryinformation which can be used for example, in protection schemes, interlocking andalarms. There are eight separate inputs and corresponding outputs available.

In this configuration, one physical input X110:BI2 is connected to the binary signaltransfer channel one. Local feeder ready and local circuit breaker open information areconnected to the BSTGGIO inputs 6 and 7. This is interlocking information fromcontrol logic. The information of detected current transformer fault is connected toinput 8.

As a consequence of sending interlocking information to remote end, also receiving ofsame information locally is needed. Therefore, remote feeder ready, remote circuitbreaker open and remote current transformer failure are connected to the binary signaltransfer function outputs. The remote binary transfer output signal is connected to thebinary output X110:SO3.

3.7 Standard configuration E

3.7.1 Applications

The standard configuration with directional overcurrent and directional earth-faultprotection, phase-voltage and frequency based protection is mainly intended for cablefeeder applications in distribution networks. The standard configuration for linecurrent differential protection includes support for in-zone transformers. Theconfiguration also includes additional options to select earth-fault protection based onadmittance, wattmetric or harmonic principle.

Standard configuration E is not designed for using all the available functionalitycontent in one relay at the same time. Frequency protection functions and thirdinstances of voltage protection functions must be added with the Application



Configuration tool. To ensure the performance of the relay, the user-specificconfiguration load is verified with the Application Configuration tool in PCM600.

The phase currents to the protection relay are fed from Rogowski or Combi sensors.The residual current to the protection relay is fed from either residually connectedCTs, an external core balance CT, neutral CT or calculated internally.

The phase voltages to the protection relay are fed from Combi sensors. The residualvoltage is calculated internally.






The functional diagrams describe the IEDs protection functionality in detail andaccording to the factory set default connections.

Line differential protection with in-zone power transformer LNPLDF1 is intended tobe the main protection offering exclusive unit protection for the power distributionlines or cables. The stabilized low stage can be blocked if the current transformerfailure is detected. The operate value of the instantaneous high stage can be multipliedby predefined settings if the ENA_MULT_HS input is activated. In this configuration,it is activated by the open status information of the remote-end circuit breaker andearth switch, and if the disconnector is not in the intermediate state. The intention ofthis connection is to lower the setting value of the instantaneous high stage bymultiplying with setting High Op value Mult, in case of internal fault.

The binary signal transfer function BSTGGIO is used for changing any binaryinformation which can be used for example, in protection schemes, interlocking andalarms. There are eight separate inputs and corresponding outputs available.

In this configuration, local feeder ready and local circuit breaker open information areconnected to the BSTGGIO inputs 6 and 7. This is interlocking information fromcontrol logic. The information of detected current transformer fault is connected toinput 8.

As a consequence of sending interlocking information to remote end, also receiving ofsame information locally is needed. Therefore, remote feeder ready, remote circuitbreaker open and remote current transformer failure are connected to the binary signaltransfer function outputs.

Section 4 Requirements for measurementtransformers

4.1 Current transformers

4.1.1 Current transformer requirements for overcurrent protection

For reliable and correct operation of the overcurrent protection, the CT has to bechosen carefully. The distortion of the secondary current of a saturated CT mayendanger the operation, selectivity, and co-ordination of protection. However, whenthe CT is correctly selected, a fast and reliable short circuit protection can be enabled.

The selection of a CT depends not only on the CT specifications but also on thenetwork fault current magnitude, desired protection objectives, and the actual CTburden. The protection settings of the protection relay should be defined in accordancewith the CT performance as well as other factors.

4.1.1.1 Current transformer accuracy class and accuracy limit factor

The rated accuracy limit factor (Fn) is the ratio of the rated accuracy limit primarycurrent to the rated primary current. For example, a protective current transformer oftype 5P10 has the accuracy class 5P and the accuracy limit factor 10. For protectivecurrent transformers, the accuracy class is designed by the highest permissiblepercentage composite error at the rated accuracy limit primary current prescribed forthe accuracy class concerned, followed by the letter "P" (meaning protection).

Table 36: Limits of errors according to IEC 60044-1 for protective current transformers

Accuracy class Current error atrated primarycurrent (%)

Phase displacement at rated primarycurrent

Composite error atrated accuracy limitprimary current (%)minutes centiradians

5P ±1 ±60 ±1.8 5

10P ±3 - - 10

The accuracy classes 5P and 10P are both suitable for non-directional overcurrentprotection. The 5P class provides a better accuracy. This should be noted also if thereare accuracy requirements for the metering functions (current metering, powermetering, and so on) of the protection relay.

The CT accuracy primary limit current describes the highest fault current magnitudeat which the CT fulfils the specified accuracy. Beyond this level, the secondary current

1MRS756498 N Section 4Requirements for measurement transformers


of the CT is distorted and it might have severe effects on the performance of theprotection relay.

In practise, the actual accuracy limit factor (Fa) differs from the rated accuracy limitfactor (Fn) and is proportional to the ratio of the rated CT burden and the actual CTburden.

The actual accuracy limit factor is calculated using the formula:

Fn the accuracy limit factor with the nominal external burden Sn

4.1.1.2 Non-directional overcurrent protection

The current transformer selectionNon-directional overcurrent protection does not set high requirements on the accuracyclass or on the actual accuracy limit factor (Fa) of the CTs. It is, however,recommended to select a CT with Fa of at least 20.

The nominal primary current I1n should be chosen in such a way that the thermal anddynamic strength of the current measuring input of the protection relay is notexceeded. This is always fulfilled when

I1n > Ikmax / 100,

Ikmax is the highest fault current.

The saturation of the CT protects the measuring circuit and the current input of theprotection relay. For that reason, in practice, even a few times smaller nominalprimary current can be used than given by the formula.

Recommended start current settingsIf Ikmin is the lowest primary current at which the highest set overcurrent stage is tooperate, the start current should be set using the formula:

Current start value < 0.7 × (Ikmin / I1n)

I1n is the nominal primary current of the CT.

The factor 0.7 takes into account the protection relay inaccuracy, current transformererrors, and imperfections of the short circuit calculations.

Section 4 1MRS756498 NRequirements for measurement transformers


The adequate performance of the CT should be checked when the setting of the highset stage overcurrent protection is defined. The operate time delay caused by the CTsaturation is typically small enough when the overcurrent setting is noticeably lowerthan Fa.

When defining the setting values for the low set stages, the saturation of the CT doesnot need to be taken into account and the start current setting is simply according to theformula.

Delay in operation caused by saturation of current transformersThe saturation of CT may cause a delayed protection relay operation. To ensure thetime selectivity, the delay must be taken into account when setting the operate timesof successive protection relays.

With definite time mode of operation, the saturation of CT may cause a delay that isas long as the time constant of the DC component of the fault current, when the currentis only slightly higher than the starting current. This depends on the accuracy limitfactor of the CT, on the remanence flux of the core of the CT, and on the operate timesetting.

With inverse time mode of operation, the delay should always be considered as beingas long as the time constant of the DC component.

With inverse time mode of operation and when the high-set stages are not used, the ACcomponent of the fault current should not saturate the CT less than 20 times thestarting current. Otherwise, the inverse operation time can be further prolonged.Therefore, the accuracy limit factor Fa should be chosen using the formula:

Fa > 20 × Current start value / I1n

The Current start value is the primary start current setting of the protection relay.

4.1.1.3 Example for non-directional overcurrent protection

The following figure describes a typical medium voltage feeder. The protection isimplemented as three-stage definite time non-directional overcurrent protection.

1MRS756498 N Section 4Requirements for measurement transformers


A071142 V1 EN

Figure 251: Example of three-stage overcurrent protection

The maximum three-phase fault current is 41.7 kA and the minimum three-phase shortcircuit current is 22.8 kA. The actual accuracy limit factor of the CT is calculated tobe 59.

The start current setting for low-set stage (3I>) is selected to be about twice thenominal current of the cable. The operate time is selected so that it is selective with thenext protection relay (not visible in Figure 251). The settings for the high-set stage andinstantaneous stage are defined also so that grading is ensured with the downstreamprotection. In addition, the start current settings have to be defined so that theprotection relay operates with the minimum fault current and it does not operate withthe maximum load current. The settings for all three stages are as in Figure 251.

For the application point of view, the suitable setting for instantaneous stage (I>>>) inthis example is 3 500 A (5.83 × I2n). I2n is the 1.2 multiple with nominal primarycurrent of the CT. For the CT characteristics point of view, the criteria given by thecurrent transformer selection formula is fulfilled and also the protection relay settingis considerably below the Fa. In this application, the CT rated burden could have beenselected much lower than 10 VA for economical reasons.

5.3 Protection communication options

Two different protection communication options are available for the protectionrelay, that is, a fiber optic link and a galvanic pilot wire link.

Multi-mode or single-mode glass fiber can be used in a fiber optic link. Select therequired glass fiber mode when ordering the protection relay. Link lengths up to 2 kmwith multi-mode fiber and link lengths up to 20 km with single-mode fiber can beachieved. The fiber optic cable used for protection communication is connected to theX16/LD connector in the protection relay. See the technical manual for moreinformation.

If a galvanic pilot wire is used as a protection communication link, the pilot wiremodem RPW600 is required. Select the pilot wire option when ordering the protectionrelay. The protection communication link always requires two modems in a protectionscheme, thus delivered in pairs of master (RPW600M) and follower (RPW600F)units. The protection relay is connected to the pilot wire modem using a single-modefiber optic cable. Thus a single-mode version of protection relay is required if the pilotwire link is used. The fiber optic cable is connected to the X16/LD connector in theprotection relay and in Ethernet FX connector in the pilot wire modem.

Setting or configuration is not needed with either of the pilot wire modem variants orwith the protection relay. Pilot wire link lengths up to 8 km with 0.8 mm2 twisted paircables can be applied. Even higher distances can be achieved with good qualitytwisted pair cables in the pilot wire link. The achieved link length also depends on thenoise levels in the installations.

The pilot wire modem has QoS LEDs in the front panel for easy diagnostics of the pilotwire link quality. The diagnostics feature does not depend on the payload over thepilot wire link and can be used for checking the quality of the intended pilot wire linkeven without installing the protection relays. In addition, a diagnostic kit is availableas an ordering option for more advanced diagnostic and logging of diagnostic



parameters of the pilot wire link. The kit consists of a CD-ROM with the RPW600Diagnostic Tool software with a built-in help, required drivers and a special serialdiagnostic cable to be connected to the console port of the modem.
