2.1
Overview
REM615 is a dedicated motor protection and control IED (intelligent electronic
device) designed for the protection, control, measurement and supervision of
asynchronous motors in manufacturing and process industry. REM615 is a member
of ABB’s Relion® product family and part of its 615 protection and control product
series. The 615 series IEDs are characterized by their compactness and withdrawableunit design.
Re-engineered from the ground up, the 615 series has been designed to unleash the
full potential of the IEC 61850 standard for communication and interoperability
between substation automation devices. Once the standard configuration IED has
been given the application-specific settings, it can directly be put into service.
The 615 series IEDs support a range of communication protocols including IEC
61850 with GOOSE messaging, IEC 61850-9-2 LE (except in RED615), IEC
60870-5-103, Modbus® and DNP3. Profibus DPV1 communication protocol is
supported by using the protocol converter SPA-ZC 302.

Audit trail
The IED offers a large set of event-logging functions. Normal process-related
events can be viewed by the normal user with Event Viewer in PCM600. Critical
system and IED security-related events are logged to a separate nonvolatile audit
trail for the administrator.
Audit trail is a chronological record of system activities that allows the
reconstruction and examination of the sequence of events and changes in an event.
Past user and process events can be examined and analyzed in a consistent method
with the help of Event List and Event Viewer in PCM600. The IED stores 2048
system events to the nonvolatile audit trail. Additionally, 1024 process events are
stored in a nonvolatile event list. Both the audit trail and event list work according
to the FIFO principle.
User audit trail is defined according to the selected set of requirements from IEEE
1686. The logging is based on predefined usernames or user categories. The user
audit trail events are accessible with IEC 61850-8-1, PCM600, LHMI and WHMI.

PCM600 Event Viewer can be used to view the audit trail events together with
normal events. Since only the administrator has the right to read audit trail,
authorization must be properly configured in PCM600. The audit trail cannot be
reset but PCM600 Event Viewer can filter data. Some of the audit trail events are
interesting also as normal process events.
To expose the audit trail events also as normal process events,
define the level parameter via Configuration/Authorization/

Communication
The IED supports a range of communication protocols including IEC 61850, 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 between the IEDs, is only enabled by the IEC 61850
communication protocol.
The IEC 61850 communication implementation supports all monitoring and
control functions. Additionally, parameter settings, disturbance recordings and
fault records can be accessed using the IEC 61850 protocol. Disturbance recordings
are available to any Ethernet-based application in the standard COMTRADE file
format. The IED can send and receive binary signals from other IEDs (so-called
horizontal communication) using the IEC61850-8-1 GOOSE profile, where the
highest performance class with a total transmission time of 3 ms is supported.
Furthermore, the IED supports sending and receiving of analog values using
GOOSE messaging. The IED meets the GOOSE performance requirements for
tripping applications in distribution substations, as defined by the IEC 61850
standard.

REM615
Application Manual
Section 2
REM615 overview
1MRS756885 H
The IED can support five simultaneous clients. If PCM600 reserves one client
connection, only four client connections are left, for example, for IEC 61850 and
Modbus.
All communication connectors, except for the front port connector, are placed on
integrated optional communication modules. The IED can be connected to Ethernetbased communication systems via the RJ-45 connector (100Base-TX) or the fibreoptic 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
external switches in the network support the RSTP protocol and that it is enabled in
the switches. Otherwise, connecting the loop topology can cause problems to the
network. The IED 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/linkdown events can cause temporary breaks in communication. For a better
performance of the self-healing loop, it is recommended that the external switch
furthest from the IED loop is assigned as the root switch (bridge priority = 0) and
the bridge priority increases towards the IED loop. The end links of the IED loop
can be attached to the same external switch or to two adjacent external switches. A
self-healing Ethernet ring requires a communication module with at least two
Ethernet interfaces for all IEDs.

Figure 6:
Self-healing Ethernet ring solution
The Ethernet ring solution supports the connection of up to 30
IEDs. If 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. Each IED has a 50-μs store-and-forward delay, and
REM615
Application Manual
23
Section 2
REM615 overview
1MRS756885 H
to fullfill the performance requirements for fast horizontal
communication, the ring size is limited to 30 IEDs.
2.7.2
Ethernet redundancy
IEC 61850 specifies a network redundancy scheme that improves the system
availability for substation communication. It is based on two complementary
protocols defined in the IEC 62439-3 standard: parallel redundancy protocol PRP-1
and high-availability seamless redundancy HSR protocol. Both protocols rely on
the duplication of all transmitted information via two Ethernet ports for one logical
network connection. Therefore, both are able to overcome the failure of a link or
switch with a zero-switchover time, thus fulfilling the stringent real-time
requirements for the substation automation horizontal communication and time
synchronization.
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 costeffective redundancy. Thus, each device incorporates a switch element that
forwards frames from port to port. The HSR/PRP option is available for REF615,
REM615, RET615, REU615 and REV615.
PRP
Each PRP node, called a doubly attached node with PRP (DAN), is attached to two
independent LANs operated in parallel. These parallel networks in PRP are called
LAN A and LAN B. The networks are completely separated to ensure failure
independence, and they can have different topologies. Both networks operate in
parallel, thus providing zero-time recovery and continuous checking of redundancy
to avoid communication failures. Non-PRP nodes, called singly attached nodes
(SANs), are either attached to one network only (and can therefore communicate
only with DANs and SANs attached to the same network), or are attached through
a redundancy box, a device that behaves like a DAN.

In case a laptop or a PC workstation is connected as a non-PRP node to one of the
PRP networks, LAN A or LAN B, it is recommended to use a redundancy box
device or an Ethernet switch with similar functionality between the PRP network
and SAN to remove additional PRP information from the Ethernet frames. In some
cases, default PC workstation adapters are not able to handle the maximum-length
Ethernet frames with the PRP trailer.
There are different alternative ways to connect a laptop or a workstation as SAN to
a PRP network.
•
•
•
Via an external redundancy box (RedBox) or a switch capable of connecting to
PRP and normal networks
By connecting the node directly to LAN A or LAN B as SAN
By connecting the node to the IED interlink port
HSR
HSR applies the PRP principle of parallel operation to a single ring, treating the
two directions 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 each node forwards the frames it receives, from one port to the other.
When the originating node receives a frame sent to itself, it discards that to avoid
loops; therefore, no ring protocol 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 IED with HSR support can be
used as a redundancy box.

Process bus
Process bus IEC 61850-9-2 defines the transmission of Sampled Measured Values
within the substation automation system. International Users Group created a
guideline IEC 61850-9-2 LE that defines an application profile of IEC 61850-9-2
to facilitate implementation and enable interoperability. Process bus is used for
distributing process data from the primary circuit to all process bus compatible
IEDs in the local network in a real-time manner. The data can then be processed by
any IED to perform different protection, automation and control functions.
UniGear Digital switchgear concept relies on the process bus together with current
and voltage sensors. The process bus enables several advantages for the UniGear
Digital like simplicity with reduced wiring, flexibility with data availability to all
IEDs, improved diagnostics and longer maintenance cycles.
With process bus the galvanic interpanel wiring for sharing busbar voltage value
can be replaced with Ethernet communication. Transmitting measurement samples
over process bus brings also higher error detection because the signal transmission
is automatically supervised. Additional contribution to the higher availability is the
possibility to use redundant Ethernet network for transmitting SMV signals.

Process bus application
The 615 series supports IEC 61850 process bus with sampled values of analog
phase voltages. The measured values are transferred as sampled values using the
IEC 61850-9-2 LE protocol which uses the same physical Ethernet network as the
IEC 61850-8-1 station bus. The intended application for sampled values is sharing
the measured phase voltages from one 615 series IED to other IEDs with phase
voltage based functions and 9-2 support.
The 615 series IEDs with process bus based applications use IEEE 1588 v2
Precision Time Protocol (PTP) according to IEEE C37.238-2011 Power Profile for
high accuracy time synchronization. With IEEE 1588 v2, the cabling infrastructure
requirement is reduced by allowing time synchronization information to be
transported over the same Ethernet network as the data communications.

Secure communication
The IED supports secure communication for WHMI and file transfer protocol. If
the Secure Communication parameter is activated, protocols require TLS based
encryption method from the client. In this case WHMI must be connected from a
Web browser using the HTTPS protocol and in case of file transfer the client must
use FTPS.

Standard configuration
REM615 is available in four alternative standard configurations. The standard
signal configuration can be altered by means of the graphical signal matrix or the
graphical application functionality of the Protection and Control IED Manager
PCM600. Further, the application configuration functionality of the IED supports
the creation of multi-layer logic functions using various logical elements including
timers and flip-flops. By combining protection functions with logic function
blocks, the IED configuration can be adapted to user-specific application
requirements.
The IED is delivered from the factory with default connections described in the
functional diagrams for binary inputs, binary outputs, function-to-function
connections and alarm LEDs. The positive measuring direction of directional
protection functions is towards the outgoing feeder.

Addition of control functions for primary devices and the
use of binary inputs and outputs
If extra control functions intended for controllable primary devices are added to the
configuration, additional binary inputs and/or outputs are needed to complement
the standard configuration.
If the number of inputs and/or outputs in a standard configuration is not sufficient,
it is possible either to modify the chosen IED standard configuration in order to
release some binary inputs or binary outputs which have originally been configured
for other purposes, or to integrate an external input/output module, for example
RIO600, to the IED.
The external I/O module’s binary inputs and outputs can be used for the less timecritical binary signals of the application. The integration enables releasing some
initially reserved binary inputs and outputs of the IED’s standard configuration.
The suitability of the IED’s binary outputs which have been selected for primary
device control should be carefully verified, for example make and carry and
breaking capacity. If the requirements for the primary device control circuit are not
met, using external auxiliary relays should be considered.

modifications, the standard configuration can also be applied for contactor
controlled motors. There is also an option for mA/RTD measurement and protection.
The IED with a standard configuration is delivered from the factory with default
settings and parameters. The end user flexibility for incoming, outgoing and
internal signal designation within the IED enables this configuration to be further
adapted to different primary circuit layouts and the related functionality needs by
modifying the internal functionality using PCM600.

The analog channels have fixed connections to the different function blocks inside
the IED’s standard configuration. However, the 12 analog channels available for
the disturbance recorder function are freely selectable as a part of the disturbance
recorder’s parameter settings.
The phase currents to the IED are fed from a current transformer. The residual
current to the IED is fed from either residually connected CTs, an external core
balance CT, neutral CT or calculated internally.
The IED offers six different settings group which can be set based on individual
needs. Each group can be activated or deactivated using the setting group settings
available in the IED.
Depending on the communication protocol the required function block needs to be
initiated in the configuration. The Application Configuration tool also includes
fixed Boolean signals TRUE and FALSE which can be used according to the
application needs.
3.3.3.1
Functional diagrams for protection
The functional diagrams describe the IEDs protection functionality in detail and
according to the factory set default connections.
Two overcurrent stages are offered for overcurrent and short-circuit protection. The
non-directional low stage PHLPTOC1 can be used for overcurrent protection
whereas instantaneous stage PHIPTOC1 can be used for short-circuit protection.
The operation of PHIPTOC1 is not blocked as default by any functionality and it
should be set over the motor start current level to avoid unnecessary operation. The
motor jam protection function JAMPTOC1 is blocked by the motor startup
protection function.

The phase reversal protection PREVPTOC1 is based on the calculated negative
phase-sequence current. It detects high negative sequence current values during
motor startup, caused by incorrectly connected phases, which in turn causes the
motor to rotate in the opposite direction.

Motor emergency startup function
The thermal overload protection MPTTR1 detects short and long term overloads
under varying load conditions. When the emergency start request is issued for the
emergency start function, it activates the corresponding input of the thermal
overload function. Restart blocking, issued by the thermal overload function,
prevents the closing of the breaker in machine overload situation. The emergency
start request removes the blocking and enables the restarting of the motor.
If the IED is ordered with RTD/mA card, the motor ambient temperature can be
measured with input RTD X130:AI8 and it is connected to the thermal overload
protection function MPTTR1.

The restart inhibit is activated for a set period when a circuit breaker is opened.
This is called remanence voltage protection where the motor has damping
remanence voltage after the circuit breaker opening. Re-closing after a too short
period of time can lead to stress for the machine and other apparatus. The
remanence voltage protection waiting time can be set by a timer function TPSGAPC1.
The restart inhibit is also activated under various conditions.

The breaker failure protection CCBRBRF1 is initiated via the START input by
number of different protection functions available in the IED. The breaker failure
protection function offers different operating modes associated with the circuit
breaker position and the measured phase and residual currents.
The breaker failure protection function has two operating outputs: TRRET and
TRBU. The TRRET operate output is used for retripping its own breaker through
TRPPTRC2_TRIP. The TRBU output is used to give a backup trip to the breaker
feeding upstream. For this purpose, the TRBU operate output signal is connected to
the binary output X100:PO2.

The operate signals from the protection functions are connected to trip logics
TRPPTRC1. The output of these trip logic functions is available at binary outputs
X100:PO3 and X100:SO1. The trip logic functions are provided with a lockout and
latching function, event generation and the trip signal duration setting. If the
lockout operation mode is selected, the binary input can be assigned to
RST_LKOUT input of the trip logic to enable external reset with a push button.
Three other trip logics TRPPTRC3...4 are also available if the IED is ordered with

circuit breaker closing. The trip circuit supervision TCSSCRB1 is blocked by the
Master Trip TRPPTRC1 and the circuit breaker open signal. The trip circuit
supervision function TCSSCBR2 is blocked by the circuit breaker close signal.
It is assumed that there is no external resistor in the circuit breaker
tripping coil circuit connected in parallel with the circuit breaker
normally open auxiliary contact.

The circuit breaker closing is enabled when the ENA_CLOSE input is activated.
The input can be activated by the configuration logic, which is a combination of
the disconnector 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 function block. The open operation for circuit breaker is always enabled.

Functional diagrams for measurement functions
The phase current inputs to the IED are measured by the three-phase current
measurement function CMMXU1. The current input is connected to the X120 card
in the back panel. The sequence current measurement CSMSQI1 measures the
sequence current and the residual current measurement RESCMMXU1 measures
the residual current.
The measurements can be seen in the LHMI and they are available under the
measurement option in the menu selection. Based on the settings, function blocks
can generate low alarm or warning and high alarm or warning signals for the
measured current values.
The load profile function LDPMSTA1 is included in the measurements sheet.
LDPMSTA1 offers the ability to observe the loading history of the corresponding
feeder.

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

Applications
The standard configuration is intended for comprehensive protection and control
functionality of the circuit breaker controlled asynchronous motors. With minor
modifications, the standard configuration can also be applied for contactor
controlled motors. There is also an option for mA/RTD measurement and protection.
The IED with a standard configuration is delivered from the factory with default
settings and parameters. The end user flexibility for incoming, outgoing and
internal signal designation within the IED enables this configuration to be further
adapted to different primary circuit layouts and the related functionality needs by
modifying the internal functionality using PCM600.

Functional diagrams
The functional diagrams describe the default input, output, alarm LED and functionto-function connections. The default connections can be viewed and changed with
PCM600 according to the application requirements.
The analog channels have fixed connections to the different function blocks inside
the IED’s standard configuration. However, the 12 analog channels available for
the disturbance recorder function are freely selectable as a part of the disturbance
recorder’s parameter settings.
The phase currents to the IED are fed from a current transformer. The residual
current to the IED is fed from either residually connected CTs, an external core
balance CT, neutral CT or calculated internally.
The phase voltages to the IED are fed from a voltage transformer.
The IED offers six different settings group which can be set based on individual
needs. Each group can be activated or deactivated using the setting group settings
available in the IED.
Depending on the communication protocol the required function block needs to be
initiated in the configuration. The Application Configuration tool also includes
fixed Boolean signals TRUE and FALSE which can be used according to the
application needs.

Functional diagrams for protection
The functional diagrams describe the IEDs protection functionality in detail and
according to the factory set default connections.
Two overcurrent stages are offered for overcurrent and short-circuit protection. The
non-directional low stage PHLPTOC1 can be used for overcurrent protection
whereas instantaneous stage PHIPTOC1 can be used for short-circuit protection.
The operation of PHIPTOC1 is not blocked as default by any functionality and it
should be set over the motor start current level to avoid unnecessary operation.
The motor jam protection function JAMPTOC1 is blocked by the motor startup
protection function.

Negative sequence overcurrent protection function
The phase reversal protection PREVPTOC1 is based on the calculated negative
phase-sequence current. It detects high negative sequence current values during
motor startup, caused by incorrectly connected phases, which in turn causes the
motor to rotate in the opposite direction.
The negative sequence and phase reversal protection are blocked if the current
circuit supervision detects failure in the current measurement circuit.

Phase reversal protection function
One stage is provided for non-directional earth-fault protection EFHPTOC1 to
detect phase-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 low stage non-directional earth-fault protection without residual voltage
requirement. However, the residual voltage can help to detect earth faults at a low
fault current level selectively and to discriminate the apparent residual current
caused, for example, by partial current transformer saturation at motor startup.
Both the directional and non-directional earth-fault are blocked by the activation of
instantaneous stage of overcurrent protection.

The emergency start function ESMGAPC1 allows motor startups although the
calculated thermal level or cumulative startup time counter is blocking the restart.
The emergency start is enabled for ten minutes after the selected binary input
X110:BI6 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
inhibit level to allow at least one motor startup.
The value of the cumulative startup time counter STTPMSU1 is set slightly
below the set restart inhibit value to allow at least one motor startup.
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
module is included).
Alarm LED 11 is activated.
A new emergency start cannot be made until the emergency start signal has been

Motor emergency startup function
The thermal overload protection MPTTR1 detects short and long term overloads
under varying load conditions. When the emergency start request is issued for the
emergency start function, it activates the corresponding input of the thermal
overload function. Restart blocking, issued by the thermal overload function,
prevents the closing of the breaker in machine overload situation. The emergency
start request removes the blocking and enables the restarting of the motor.
If IED is ordered with RTD/mA card, the motor ambient temperature can be
measured with input RTD X130:AI8 and it is connected to the thermal overload
protection function MPTTR1.

The restart inhibit is activated for a set period when a circuit breaker is opened.
This is called remanence voltage protection where the motor has damping
remanence voltage after the circuit breaker opening. Reclosing after a too short
period of time can lead to stress for the machine and other apparatus. The
remanence voltage protection waiting time can be set by a timer function TPSGAPC1.
The restart inhibit is also activated under various conditions.

An external restart inhibit is activated by a binary input X120:BI4
With the motor startup supervision function STTPMSU1, the starting of the motor
is supervised by monitoring three-phase currents or the status of the energizing
circuit breaker of the motor. When the emergency start request is activated by
ESMGAPC1 and STTPMSU1 is in lockout state, which inhibits motor starting, the
lockout is deactivated and emergency starting is available.
The upstream blocking from the motor startup is connected to the binary output
X110:SO1. The output is used for sending a blocking signal to the relevant
overcurrent protection stage of the IED at the infeeding bay.

The breaker failure protection CCBRBRF1 is initiated via the START input by
number of different protection functions available in the IED. The breaker failure
protection function offers different operating modes associated with the circuit
breaker position and the measured phase and residual currents.
The breaker failure protection function has two operating outputs: TRRET and
TRBU. The TRRET operate output is used for retripping its own breaker through
TRPPTRC2_TRIP. The TRBU output is used to give a backup trip to the breaker
feeding upstream. For this purpose, the TRBU operate output signal is connected to
the binary output X100:PO2.

General start and operate signals
The operate signals from the protection functions are connected to trip logics
TRPPTRC1. The output of these trip logic functions is available at binary output
X100:PO3 and also at X100:SO1. The trip logic functions are provided with a
lockout and latching function, event generation and the trip signal duration setting.
If the lockout operation mode is selected, binary input X110:BI7 can be assigned to
RST_LKOUT input of the trip logic to enable external reset with a push button.
Three other trip logics TRPPTRC3...4 are also available if the IED is ordered with
high speed binary outputs options.

Logic for circuit breaker monitoring alarm
Two separate trip circuit supervision functions are included: TCSSCBR1 for power
output X100:PO3 for Master Trip and TCSSCBR2 for power output X100:PO4 for
circuit breaker closing. The trip circuit supervision TCSSCRB1 is blocked by the
Master Trip TRPPTRC1 and the circuit breaker open signal. The trip circuit
supervision TCSSCBR2 is blocked by the circuit breaker close signal.
It is assumed that there is no external resistor in the circuit breaker
tripping coil circuit connected in parallel with the circuit breaker
normally open auxiliary contact.

The circuit breaker closing is enabled when the ENA_CLOSE input is activated.
The input can be activated by the configuration logic, which is a combination of
the disconnector 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 function block. The open operation for circuit breaker is always enabled.
Connect the additional signals required by the application for
closing and opening of the circuit breaker.

Functional diagrams for measurements functions
The phase current inputs to the IED are measured by the three-phase current
measurement function CMMXU1. The current input is connected to the X120 card
in the back panel. The sequence current measurement CSMSQI1 measures the
sequence current and the residual current measurement RESCMMXU1 measures
the residual current.
The three-phase voltage inputs to the IED are measured by the voltage
measurement function VMMXU1 respectively. The voltage input is connected to
the X130 card in the back panel. The sequence voltage measurement VSMSQI1
measures the sequence voltage.
The measurements can be seen in the LHMI and they are available under the
measurement option in the menu selection. Based on the settings, function blocks
can generate low alarm or warning and high alarm or warning signals for the
measured current values.
The frequency measurement FMMXU1 of the power system and the three-phase
power measurement PEMMXU1 are available. The load profile function
LDPMSTA1 is included in the measurements sheet. LDPMSTA1 offers the ability
to observe the loading history of the corresponding feeder.

The configuration also includes voltage operate, motor startup and thermal alarm,
blocking logic for phase under voltage protection and logic for remanence voltage.
The restart inhibit is activated for a set period when a circuit breaker is in open
state. This is called remanence voltage protection where the motor has damping
remanence voltage after the opening of a circuit breaker. Reclosing after a short
period of time can lead to stress for the machine and other apparatus. The
remanence voltage protection waiting time can be set by a timer function TPSGAPC1.

Standard configuration C
3.5.1
Applications
The standard configuration for motor protection with current and voltage based
protection and measurements functions is intended for comprehensive protection
and control functionality of the circuit breaker controlled asynchronous motors.
With minor modifications, the standard configuration can also be applied for
contactor controlled motors.
The IED with a standard configuration is delivered from the factory with default
settings and parameters. The end user flexibility for incoming, outgoing and
internal signal designation within the IED enables this configuration to be further

Functional diagrams
The functional diagrams describe the default input, output, alarm LED and functionto-function connections. The default connections can be viewed and changed with
PCM600 according to the application requirements.
The analog channels have fixed connections to the different function blocks inside
the IED’s standard configuration. However, the 12 analog channels available for
the disturbance recorder function are freely selectable as a part of the disturbance
recorder’s parameter settings.
The phase currents to the IED are fed from a current transformer. The residual
current to the IED is fed from either residually connected CTs, an external core
balance CT, neutral CT or calculated internally.
The phase voltages to the IED are fed from a voltage transformer. The residual
voltage to the IED is fed from either residually connected VTs, an open delta
connected VT or calculated internally.
The IED offers six different settings group which can be set based on individual
needs. Each group can be activated or deactivated using the setting group settings
available in the IED.
Depending on the communication protocol the required function block needs to be
initiated in the configuration. The Application Configuration tool also includes
fixed Boolean signals TRUE and FALSE which can be used according to the
application needs.
3.5.3.1
Functional diagrams for protection
The functional diagrams describe the IEDs protection functionality in detail and
according to the factory set default connections.
Two overcurrent stages are offered for overcurrent and short-circuit protection. The
non-directional low stage PHLPTOC1 can be used for overcurrent protection
whereas instantaneous stage PHIPTOC1 can be used for short-circuit protection.

One stage is provided for non-directional earth-fault protection EFHPTOC1 to
detect phase-to-earth faults that may be the result of, for example, insulation
ageing. A directional protection stage DEFLPDEF1 can also be used as a low stage
non-directional earth-fault protection without residual voltage requirement.
However, the residual voltage can help to detect earth faults at a low fault current
level selectively and to discriminate the apparent residual current caused, for
example, by partial current transformer saturation at motor startup.
Both the directional and non-directional earth-fault are blocked by the activation of
instantaneous stage of overcurrent protection.

The restart inhibit is activated for a set period when a circuit breaker is opened.
This is called remanence voltage protection where the motor has damping
remanence voltage after the circuit breaker opening. Re-closing after a too short

An external restart inhibit is activated by a binary input X130:BI1
With the motor startup supervision function STTPMSU1, the starting of the motor
is supervised by monitoring three-phase currents or the status of the energizing
circuit breaker of the motor. When the emergency start request is activated by
ESMGAPC1 and STTPMSU1 is in lockout state, which inhibits motor starting, the
lockout is deactivated and emergency starting is available.
The upstream blocking from the motor startup is connected to the binary output

The undervoltage protection PHPTUV1 offers protection against abnormal phase
voltage conditions. Positive sequence undervoltage PSPTUV and negative
sequence overvoltage NSPTOV protection functions are included to protect the
machine against single-phasing, excessive unbalance between phases and abnormal
phase order.
A failure in the voltage measuring circuit is detected by the fuse failure function.
The activation is connected to block undervoltage protection functions and voltage
based unbalance protection functions to avoid faulty tripping. The undervoltage
protection PHPTUV1 in addition is also blocked during motor startup to prevent
unwanted operation in case of short voltage drop, whereas positive and negative
sequence protection is blocked when the network rotation direction changes.

The breaker failure protection CCBRBRF1 is initiated via the START input by
number of different protection functions available in the IED. The breaker failure
protection function offers different operating modes associated with the circuit
breaker position and the measured phase and residual currents.
The breaker failure protection function has two operating outputs: TRRET and
TRBU. The TRRET operate output is used for retripping its own breaker through
TRPPTRC2_TRIP. The TRBU output is used to give a backup trip to the breaker
feeding upstream. For this purpose, the TRBU operate output signal is connected to
the binary output X100:PO2.

Three arc protection ARCSARC1...3 stages are included as an optional function.
The arc protection offers individual function blocks for three arc sensors that can
be connected to the IED. Each arc protection function block has two different
operation modes with or without the phase and residual current check.
The operate signals from ARCSARC1...3 are connected to both trip logic
TRPPTRC1 and TRPPTRC2. If the IED has been ordered with high speed binary
outputs, individual operate signals from ARCSARC1...3 are connected to dedicated
trip logic TRPPTRC3...5. The outputs of TRPPTRC3...5 are available at high speed
outputs X110:HSO1, X110:HSO2 and X110:HSO3.

The operate signals from the protections are connected to trip logics TRPPTRC1.
The output of these trip logic functions is available at binary output X100:PO3 and
also at X100:SO1. The trip logic functions are provided with a lockout and latching
function, event generation and the trip signal duration setting. If the lockout
operation mode is selected, binary input X120:BI4 can be assigned to RST_LKOUT
input of the trip logic to enable external reset with a push button.
Three other trip logics TRPPTRC3...4 are also available if the IED is ordered with

Functional diagrams for measurement functions
The phase current inputs to the IED are measured by the three-phase current
measurement function CMMXU1. The current input is connected to the X120 card
in the back panel. The sequence current measurement CSMSQI1 measures the
sequence current and the residual current measurement RESCMMXU1 measures
the residual current.
The three-phase voltage inputs to the IED are measured by the voltage
measurement function VMMXU1. The voltage input is connected to the X130 card
in the back panel. The sequence voltage measurement VSMSQI1 measures the
sequence voltage and the residual voltage measurement RESVMMXU1 measures
the residual voltage.
The measurements can be seen in the LHMI and they are available under the
measurement option in the menu selection. Based on the settings, function blocks
can generate low alarm or warning and high alarm or warning signals for the
measured current values.
The frequency measurement FMMXU1 of the power system and the three-phase
power measurement PEMMXU1 are available. The load profile function
LDPMSTA1 is included in the measurements sheet. LDPMSTA1 offers the ability
to observe the loading history of the corresponding feeder.

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

Standard configuration D
3.6.1
Applications
The standard configuration for motor protection with current and voltage based
protection and measurements functions is mainly intended for comprehensive
protection and control functionality of circuit breaker controlled asynchronous
motors. With minor modifications this standard configuration can be applied also
for contactor controlled motors.
The IED with a standard configuration is delivered from the factory with default
settings and parameters. The end user flexibility for incoming, outgoing and
internal signal designation within the IED enables this configuration to be further
adapted to different primary circuit layouts and the related functionality needs by
modifying the internal functionality using PCM600.

Sensor settings
This chapter gives short examples on how to define the correct parameters for
sensors. See the technical manual for detailed information about sensor settings.
Sensors have corrections factors, measured and verified by the
sensor manufacturer, to increase the measurement accuracy of
primary values. Correction factors are recommended to be set. Two
types of correction factors are available for voltage and rogowski
sensors. The Amplitude correction factor is named Amplitude corr.
A(B/C) and Angle correction factor is named Angle corr A(B/C).
These correction factors can be found on the Sensor's rating plate. If
REM615
Application Manual
119
Section 3
REM615 standard configurations
1MRS756885 H
the correction factors are not available, contact the sensor
manufacturer for more information.
Rogowski sensor setting example
In this example, an 80 A/0.150 V at 50 Hz sensor is used and the application has a
150 A nominal current (In). As the Rogowski sensor is linear and does not saturate,
the 80 A/0.150 V at 50 Hz sensor also works as a 150 A/0.28125 V at 50 Hz
sensor. When defining another primary value for the sensor, also the nominal
voltage has to be redefined to maintain the same transformation ratio. However, the
setting in the IED (Rated Secondary Value) is not in V but in mV/Hz, which makes
the same setting value valid for both 50 and 60 Hz nominal frequency.

Voltage sensor setting example
The voltage sensor is based on the resistive divider or capacitive divider principle.
Therefore, the voltage is linear throughout the whole measuring range. The output
signal is a voltage, directly proportional to the primary voltage. For the voltage
sensor all parameters are readable directly from its rating plate and conversions are
not needed.
In this example the system phase-to-phase voltage rating is 10 kV. Thus, the
Primary voltage parameter is set to 10 kV. For IEDs with sensor measurement
support the Voltage input type is always set to “CVD sensor” and it cannot be
changed. The same applies for the VT connection parameter which is always set to
“WYE” type. The division ratio for ABB voltage sensors is most often 10000:1.
Thus, the Division ratio parameter is usually set to “10000”. The primary voltage is
proportionally divided by this division ratio.

Functional diagrams
The functional diagrams describe the default input, output, alarm LED and functionto-function connections. The default connections can be viewed and changed with
PCM600 according to the application requirements.
The analog channels have fixed connections to the different function blocks inside
the IED’s standard configuration. However, the 12 analog channels available for
the disturbance recorder function are freely selectable as a part of the disturbance
recorder’s parameter settings.
The phase currents to the IED are fed from Rogowski or Combi sensors. The
residual current to the IED is fed from either residually connected CTs, an external
core balance CT, neutral CT or calculated internally.
The phase voltages to the IED are fed from Combi sensors. The residual voltage is
calculated internally.
The IED offers six different settings group which can be set based on individual
needs. Each group can be activated or deactivated using the setting group settings
available in the IED.
Depending on the communication protocol the required function block needs to be
initiated in the configuration. The Application Configuration tool also includes
REM615

Section 3

fixed Boolean signals TRUE and FALSE which can be used according to the
application needs.

Functional diagrams for protection
The functional diagrams describe the IEDs protection functionality in detail and
according to the factory set default connections.
Two overcurrent stages are offered for overcurrent and short-circuit protection. The
non-directional low stage PHLPTOC1 can be used for overcurrent protection
whereas instantaneous stage PHIPTOC1 can be used for short-circuit protection.
The operation of PHIPTOC1 is not blocked as default by any functionality and it
should be set over the motor start current level to avoid unnecessary operation.
The motor jam protection function JAMPTOC1 is blocked by the motor startup
protection function.

Negative sequence overcurrent protection function
The phase reversal protection PREVPTOC1 is based on the calculated negative
phase sequence current. It detects high negative sequence current values during
motor startup, caused by incorrectly connected phases, which in turn causes the
motor to rotate in the opposite direction.
The negative sequence and phase reversal protection are blocked if the current
circuit supervision detects failure in the current measurement circuit.

One stage is provided for non-directional earth-fault protection EFHPTOC1 to
detect phase-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 low stage non-directional earth-fault protection without residual voltage
requirement. However, the residual voltage can help to detect earth faults at a low
fault current level selectively and to discriminate the apparent residual current
caused, for example, by partial current transformer saturation at motor startup.
Both the directional and non-directional earth-fault are blocked by the activation of
instantaneous stage of overcurrent protection.

prevents the closing of the breaker in machine overload situation. The emergency

The restart inhibit is activated for a set period when a circuit breaker is opened.
This is called remanence voltage protection where the motor has damping
remanence voltage after the circuit breaker opening. Re-closing after a too short
period of time can lead to stress for the machine and other apparatus. The
remanence voltage protection waiting time can be set by a timer function TPSGAPC1.

The undervoltage protection PHPTUV1 offers protection against abnormal phase
voltage conditions. Positive sequence undervoltage PSPTUV1 and negative
sequence overvoltage NSPTOV1 protection functions are included to protect the
machine against single-phasing, excessive unbalance between phases and abnormal
phase order.
The undervoltage protection PHPTUV1 is blocked during motor startup to prevent

number of different protection functions available in the IED. The breaker failure
protection function offers different operating modes associated with the circuit
breaker position and the measured phase and residual currents.
The breaker failure protection function has two operating outputs: TRRET and

output X100:PO3 for Master Trip and TCSSCBR2 for power output X100:PO4 for
circuit breaker closing. The trip circuit supervision TCSSCRB1 is blocked by both
the Master Trips TRPPTRC1 and TRPPTRC2 and the binary input X110:BI1
indicating IED plug out. The trip circuit supervision TCSSCBR2 is blocked by the

Disconnector and earth-switch control logic
The circuit breaker closing is enabled when the ENA_CLOSE input is activated.
The input can be activated by the configuration logic, which is a combination of
the disconnector 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 is
either open (in test position) or close (in service position). This output, together
with the open earth-switch and non-active trip signals, spring charged status and nonactive trip circuit supervision alarm, activates the close-enable signal to the circuit
breaker control function block. The open operation for circuit breaker is always
enabled.

restart inhibit is activated for a set period when a circuit breaker is in open state.
This is called remanence voltage protection where the motor has damping
remanence voltage after the opening of a circuit breaker. Re-closing after a short

Current transformers
4.1.1
Current transformer requirements for non-directional
overcurrent protection
For reliable and correct operation of the overcurrent protection, the CT has to be
chosen carefully. The distortion of the secondary current of a saturated CT may
endanger the operation, selectivity, and co-ordination of protection. However,
when the 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 the
network fault current magnitude, desired protection objectives, and the actual CT
burden. The protection settings of the IED should be defined in accordance with
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 primary
current to the rated primary current. For example, a protective current transformer
of type 5P10 has the accuracy class 5P and the accuracy limit factor 10. For
protective current transformers, the accuracy class is designed by the highest
permissible percentage composite error at the rated accuracy limit primary current
prescribed for the accuracy class concerned, followed by the letter "P" (meaning
protection).
Table 35:

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

The CT accuracy primary limit current describes the highest fault current
magnitude at which the CT fulfils the specified accuracy. Beyond this level, the
secondary current of the CT is distorted and it might have severe effects on the
performance of the protection IED.
In practise, the actual accuracy limit factor (Fa) differs from the rated accuracy
limit factor (Fn) and is proportional to the ratio of the rated CT burden and the
actual CT burden.
The actual accuracy limit factor is calculated using the formula:
Fa ≈ Fn ×
Sin + Sn
Sin + S

Fn

Non-directional overcurrent protection
The current transformer selection
Non-directional overcurrent protection does not set high requirements on the
accuracy class 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
and dynamic strength of the current measuring input of the IED is not exceeded.
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 the
IED. For that reason, in practice, even a few times smaller nominal primary current
can be used than given by the formula.
Recommended start current settings
If Ikmin is the lowest primary current at which the highest set overcurrent stage is to
operate, the start current should be set using the formula:
Current start value < 0.7 x (Ikmin / I1n)
I1n is the nominal primary current of the CT.

REM615
Application Manual
1MRS756885 H
Section 4
Requirements for measurement transformers
The factor 0.7 takes into account the protection IED inaccuracy, current
transformer errors, and imperfections of the short circuit calculations.
The adequate performance of the CT should be checked when the setting of the
high set stage overcurrent protection is defined. The operate time delay caused by
the CT saturation is typically small enough when the overcurrent setting is
noticeably lower than Fa.
When defining the setting values for the low set stages, the saturation of the CT
does not need to be taken into account and the start current setting is simply
according to the formula.
Delay in operation caused by saturation of current transformers
The saturation of CT may cause a delayed IED operation. To ensure the time
selectivity, the delay must be taken into account when setting the operate times of
successive IEDs.
With definite time mode of operation, the saturation of CT may cause a delay that
is as long as the time the constant of the DC component of the fault current, when
the current is only slightly higher than the starting current. This depends on the
accuracy limit factor of the CT, on the remanence flux of the core of the CT, and
on the operate time setting.
With inverse time mode of operation, the delay should always be considered as
being as 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
AC component of the fault current should not saturate the CT less than 20 times the
starting 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 IED.

Figure 204:
Example of three-stage overcurrent protection
The maximum three-phase fault current is 41.7 kA and the minimum three-phase
short circuit current is 22.8 kA. The actual accuracy limit factor of the CT is
calculated to be 59.
The start current setting for low-set stage (3I>) is selected to be about twice the
nominal current of the cable. The operate time is selected so that it is selective with
the next IED (not visible in the figure above). The settings for the high-set stage
and instantaneous stage are defined also so that grading is ensured with the
downstream protection. In addition, the start current settings have to be defined so
that the IED operates with the minimum fault current and it does not operate with
the maximum load current. The settings for all three stages are as in the figure above.
For the application point of view, the suitable setting for instantaneous stage (I>>>)
in this example is 3 500 A (5.83 x I2n). For the CT characteristics point of view, the
criteria given by the current transformer selection formula is fulfilled and also the
IED setting is considerably below the Fa. In this application, the CT rated burden

IRF
The IRF contact functions as an output contact for the self-supervision system of
the protection IED. Under normal operating conditions, the IED is energized and
the contact is closed (X100/3-5). When a fault is detected by the self-supervision
system or the auxiliary voltage is disconnected, the output contact drops off and the
contact closes (X100/3-4).
