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.

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.

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 DPV1communication 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
Section 2 1MRS756885 MREM615 overview
24 REM615Application Manual
(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).
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.
Section 2 1MRS756885 MREM615 overview
26 REM615Application Manual
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.

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.
1MRS756885 M Section 2REM615 overview
REM615 27Application Manual
• 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.

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.
Section 2 1MRS756885 MREM615 overview
28 REM615Application Manual
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.

3.1 Standard configuration
REM615 is available with four alternative standard configurations. The standardsignal configuration can be altered by means of the graphical signal matrix or thegraphical application functionality of the Protection and Control IED ManagerPCM600. Further, the application configuration functionality of the relay supports thecreation of multi-layer logic functions using various logical elements including timersand flip-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 REM615 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.
1MRS756885 M Section 3REM615 standard configurations
REM615 43Application Manual
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.
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 IEDs protection functionality in detail andaccording to the factory set default connections.
Two overcurrent stages are offered for overcurrent and short-circuit protection. Thenon-directional low stage PHLPTOC1 can be used for overcurrent protection whereasinstantaneous stage PHIPTOC1 can be used for short-circuit protection. Theoperation of PHIPTOC1 is not blocked as default by any functionality and it should beset over the motor start current level to avoid unnecessary operation. The Motor loadjam protection function JAMPTOC1 is blocked by the motor start-up protectionfunction.

The emergency start function ESMGAPC1 allows motor start-ups although thecalculated thermal level or cumulative start-up time counter is blocking the restart.The emergency start is enabled for ten minutes after the selected binary inputX120:BI1 is energized.
On the rising edge of the emergency start signal, various events occur.
• The calculated thermal level in MPTTR1 is set slightly below the restart inhibitlevel to allow at least one motor start-up.
• The value of the cumulative start-up time counter STTPMSU1 is set slightlybelow the set restart inhibit value to allow at least one motor start-up.
• The set start value of the MAPGAPC1 function is increased (or decreased)depending on the Start value Add setting (only if the optional RTD/mA moduleis included).
• Alarm LED 11 is activated.
A new emergency start cannot be made until the emergency start signal has been resetand the emergency start time has expired.

Figure 22: Motor emergency start-up function
The thermal overload protection for motors MPTTR1 detects short and long termoverloads under varying load conditions. When the emergency start request is issuedfor the emergency start function, it activates the corresponding input of the thermaloverload function. Restart blocking, issued by the thermal overload function, preventsthe closing of the breaker in machine overload situation. The emergency start requestremoves the blocking and enables the restarting of the motor.

The restart inhibit is activated for a set period when a circuit breaker is opened. Thisis called remanence voltage protection where the motor has damping remanencevoltage after the circuit breaker opening. Re-closing after a too short period of timecan lead to stress for the machine and other apparatus. The remanence voltageprotection waiting time can be set by a timer function TPSGAPC1.
The restart inhibit is also activated under various conditions.
• An active trip command• Motor start-up supervision has issued lockout• Motor unbalance function has issued restart blocking• An external restart inhibit is activated by a binary input X120:BI4
With the motor start-up supervision function STTPMSU1, the starting of the motor issupervised by monitoring three-phase currents or the status of the energizing circuitbreaker of the motor. When the emergency start request is activated by ESMGAPC1and STTPMSU1 is in lockout state, which inhibits motor starting, the lockout isdeactivated and emergency starting is available.

Figure 35: Logic for circuit breaker monitoring alarm
Two separate trip circuit supervision functions are included: TCSSCBR1 for poweroutput X100:PO3 for master trip and TCSSCBR2 for power output X100:PO4 forcircuit breaker closing. The trip circuit supervision TCSSCRB1 is blocked by themaster trip TRPPTRC1 and the circuit breaker open signal. The trip circuitsupervision function TCSSCBR2 is blocked by the circuit breaker close signal.
It is assumed that there is no external resistor in the circuit breakertripping coil circuit connected in parallel with the circuit breakernormally open auxiliary contact.

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 breaker truck and earth-switch position status, status of the trip logics,gas pressure alarm and circuit breaker spring charging status. In the configuration,only trip logic activates the close-enable signal to the circuit-breaker control functionblock. The open operation for circuit breaker is always enabled.
Connect the additional signals required by the application for closingand opening of the circuit breaker.

The configuration also includes logic for remanence voltage. The restart inhibit isactivated for a set period when a circuit breaker is in open state. This is calledremanence voltage protection where the motor has damping remanence voltage afterthe opening of a circuit breaker. Reclosing after a short period of time can lead to stressfor the machine and other apparatus. The remanence voltage protection waiting timecan be set by a timer function TPSGAPC1.

3.4.3 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 phase voltages to the protection relay are fed from a voltage transformer.
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.
Depending on the communication protocol the required function block needs to beinstantiated in the configuration.

One stage is provided for non-directional earth-fault protection EFHPTOC1 to detectphase-to-earth faults that may be result of, for example, insulation ageing. In addition,there is a directional protection stage DEFLPDEF1 which can also be used as a lowstage non-directional earth-fault protection without residual voltage requirement.However, the residual voltage can help to detect earth faults at a low fault current levelselectively and to discriminate the apparent residual current caused, for example, bypartial current transformer saturation at motor start-up.
Both the directional and non-directional earth-fault are blocked by the activation ofinstantaneous stage of overcurrent protection.

The thermal overload protection for motors MPTTR1 detects short and long termoverloads under varying load conditions. When the emergency start request is issuedfor the emergency start function, it activates the corresponding input of the thermaloverload function.

The restart inhibit is activated for a set period when a circuit breaker is opened. Thisis called remanence voltage protection where the motor has damping remanencevoltage after the circuit breaker opening. Reclosing after a too short period of time canlead to stress for the machine and other apparatus. The remanence voltage protectionwaiting time can be set by a timer function TPSGAPC1.
The restart inhibit is also activated under various conditions.
• An active trip command• Motor start-up supervision has issued lockout• Motor unbalance function has issued restart blocking• An external restart inhibit is activated by a binary input X120:BI4

With the motor start-up supervision function STTPMSU1, the starting of the motor issupervised by monitoring three-phase currents or the status of the energizing circuitbreaker of the motor. When the emergency start request is activated by ESMGAPC1and STTPMSU1 is in lockout state, which inhibits motor starting, the lockout isdeactivated and emergency starting is available.
The upstream blocking from the motor start-up is connected to the binary outputX110:SO1. The output is used for sending a blocking signal to the relevantovercurrent protection stage of the IED at the infeeding bay.

The three-phase undervoltage protection PHPTUV1 offers protection againstabnormal phase voltage conditions. The positive-sequence undervoltage protectionPSPTUV1 and negative-sequence overvoltage protection NSPTOV1 functions areincluded to protect the machine against single-phasing, excessive unbalance betweenphases and abnormal phase order.
A failure in the voltage measuring circuit is detected by the fuse failure function. Theactivation is connected to block undervoltage protection functions and voltage basedunbalance protection functions to avoid faulty tripping. The three-phase undervoltageprotection PHPTUV1 in addition is also blocked during motor start-up to preventunwanted operation in case of a short voltage drop.

3.5.3 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 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 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.
Depending on the communication protocol the required function block needs to beinstantiated in the configuration.
3.5.3.1 Functional diagrams for protection
The functional diagrams describe the IEDs protection functionality in detail andaccording to the factory set default connections.
Two overcurrent stages are offered for overcurrent and short-circuit protection. Thenon-directional low stage PHLPTOC1 can be used for overcurrent protection whereasinstantaneous stage PHIPTOC1 can be used for short-circuit protection. Theoperation of PHIPTOC1 is not blocked as default by any functionality and it should beset over the motor start current level to avoid unnecessary operation. The motor load

The phase reversal protection PREVPTOC1 is based on the calculated negative phasesequence current. It detects high negative sequence current values during motor start-up, caused by incorrectly connected phases, which in turn causes the motor to rotatein the opposite direction.
The negative-sequence and phase reversal protection are blocked if the current circuitsupervision detects failure in the current measurement circuit or when the networkrotation direction changes.

One stage is provided for non-directional earth-fault protection EFHPTOC1 to detectphase-to-earth faults that may be the result of, for example, insulation ageing. Adirectional protection stage DEFLPDEF1 can also be used as a low stage non-directional earth-fault protection without residual voltage requirement. However, theresidual voltage can help to detect earth faults at a low fault current level selectivelyand to discriminate the apparent residual current caused, for example, by partialcurrent transformer saturation at motor start-up.
Both the directional and non-directional earth-fault are blocked by the activation ofinstantaneous stage of overcurrent protection.

The emergency start function ESMGAPC1 allows motor start-ups although thecalculated thermal level or cumulative start-up time counter is blocking the restart.The emergency start is enabled for ten minutes after the selected binary inputX120:BI1 is energized.
On the rising edge of the emergency start signal, various events occur.
• The calculated thermal level in MPTTR1 is set slightly below the restart inhibitlevel to allow at least one motor start-up.
• The value of the cumulative start-up time counter STTPMSU1 is set slightlybelow the set restart inhibit value to allow at least one motor start-up.
• Alarm LED 11 is activated.
A new emergency start cannot be made until the emergency start signal has been resetand the emergency start time has expired.

The thermal overload protection for motors MPTTR1 detects short and long termoverloads under varying load conditions. When the emergency start request is issuedfor the emergency start function, it activates the corresponding input of the thermaloverload function. Restart blocking, issued by the thermal overload function, preventsthe closing of the breaker in machine overload situation. The emergency start requestremoves the blocking and enables the restarting of the motor.

The restart inhibit is activated for a set period when a circuit breaker is opened. Thisis called remanence voltage protection where the motor has damping remanencevoltage after the circuit breaker opening. Re-closing after a too short period of timecan lead to stress for the machine and other apparatus. The remanence voltageprotection waiting time can be set by a timer function TPSGAPC1.
The restart inhibit is also activated under various conditions.
• An active trip command• Motor start-up supervision has issued lockout• Motor unbalance function has issued restart blocking• An external restart inhibit is activated by a binary input X130:BI1
With the motor start-up supervision function STTPMSU1, the starting of the motor issupervised by monitoring three-phase currents or the status of the energizing circuitbreaker of the motor. When the emergency start request is activated by ESMGAPC1and STTPMSU1 is in lockout state, which inhibits motor starting, the lockout isdeactivated and emergency starting is available.
The upstream blocking from the motor start-up is connected to the binary outputX110:SO1. The output is used for sending a blocking signal to the relevantovercurrent protection stage of the IED at the infeeding bay.

The three-phase undervoltage protection PHPTUV1 offers protection againstabnormal phase voltage conditions. Positive-sequence undervoltage protectionPSPTUV and negative-sequence overvoltage protection NSPTOV functions areincluded to protect the machine against single-phasing, excessive unbalance betweenphases and abnormal phase order.
A failure in the voltage measuring circuit is detected by the fuse failure function. Theactivation is connected to block undervoltage protection functions and voltage basedunbalance protection functions to avoid faulty tripping. The three-phase undervoltageprotection PHPTUV1 in addition is also blocked during motor start-up to preventunwanted operation in case of short voltage drop, whereas positive and negativesequence protection is blocked when the network rotation direction changes.

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.

3.6.3 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.
Section 3 1MRS756885 MREM615 standard configurations
120 REM615Application Manual
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 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.
Depending on the communication protocol the required function block needs to beinstantiated in the configuration.
3.6.3.1 Functional diagrams for protection
The functional diagrams describe the IEDs protection functionality in detail andaccording to the factory set default connections.
Two overcurrent stages are offered for overcurrent and short-circuit protection. Thenon-directional low stage PHLPTOC1 can be used for overcurrent protection whereasinstantaneous stage PHIPTOC1 can be used for short-circuit protection. Theoperation of PHIPTOC1 is not blocked as default by any functionality and it should beset over the motor start current level to avoid unnecessary operation.
The motor load jam protection function JAMPTOC1 is blocked by the motor start-upprotection function.

The phase reversal protection PREVPTOC1 is based on the calculated negative phasesequence current. It detects high negative sequence current values during motor start-up, caused by incorrectly connected phases, which in turn causes the motor to rotatein the opposite direction.
The negative-sequence and phase reversal protection are blocked if the current circuitsupervision detects failure in the current measurement circuit.

One stage is provided for non-directional earth-fault protection EFHPTOC1 to detectphase-to-earth faults that may be result of, for example, insulation ageing. In addition,there is a directional protection stage DEFLPDEF1 which can also be used as a lowstage non-directional earth-fault protection without residual voltage requirement.However, the residual voltage can help to detect earth faults at a low fault current levelselectively and to discriminate the apparent residual current caused, for example, bypartial current transformer saturation at motor start-up.
Both the directional and non-directional earth-fault are blocked by the activation ofinstantaneous stage of overcurrent protection.

The emergency start function ESMGAPC1 allows motor start-ups although thecalculated thermal level or cumulative start-up time counter is blocking the restart.The emergency start is enabled for ten minutes after the selected binary input isenergized. However it should be noted that by default no binary inputs are provided toperform emergency start operation.
On the rising edge of the emergency start signal, various events occur.
• The calculated thermal level in MPTTR1 is set slightly below the restart inhibitlevel to allow at least one motor start-up.
• The value of the cumulative start-up time counter STTPMSU1 is set slightlybelow the set restart inhibit value to allow at least one motor start-up.
A new emergency start cannot be made until the emergency start signal has been resetand the emergency start time has expired.

The thermal overload protection for motors MPTTR1 detects short and long termoverloads under varying load conditions. When the emergency start request is issuedfor the emergency start function, it activates the corresponding input of the thermaloverload function. Restart blocking, issued by the thermal overload function, preventsthe closing of the breaker in machine overload situation. The emergency start requestremoves the blocking and enables the restarting of the motor.

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 same TRRET output is also connected to the binary outputX100:PO4.

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 breaker truck and earth-switch position status, status of the trip logics,gas pressure alarm and circuit-breaker spring charging status.
The OKPOS output from DCSXSWI defines if the disconnector or breaker truck iseither open (in test position) or close (in service position). This output, together withthe open earth-switch and non-active trip signals, spring charged status and non-activetrip circuit supervision alarm, activates the close-enable signal to the circuit-breakercontrol function block. The open operation for circuit breaker is always enabled.

The configuration also includes voltage operate, motor start-up and thermal alarm,blocking logic for phase under voltage protection, blocking logic for phase revesal andnegative-sequence overcurrent protection and logic for remanence voltage. Therestart inhibit is activated for a set period when a circuit breaker is in open state. Thisis called remanence voltage protection where the motor has damping remanencevoltage after the opening of a circuit breaker. Re-closing after a short period of timecan lead to stress for the machine and other apparatus. The remanence voltageprotection waiting time can be set by a timer function TPSGAPC1.

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 33: 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
1MRS756885 M Section 4Requirements for measurement transformers
REM615 145Application Manual
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:
F FS S
S Sa n
in n
in
≈ ×
+
+
A071141 V1 EN
Fn the accuracy limit factor with the nominal external burden Sn
Sin the internal secondary burden of the CT
S the actual external burden
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 1MRS756885 MRequirements for measurement transformers
146 REM615Application Manual
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.
1MRS756885 M Section 4Requirements for measurement transformers
REM615 147Application Manual
A071142 V1 EN
Figure 204: 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 204). 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 204.
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.
