protection and control of the power transformer, the REM630 IEDs with
preconfiguration A are used for the circuit-breaker and contactor operated motor
feeders. The motor start-up signal from each REM630 is connected to the “Restart
inhibit” inputs of the other REM630s. Hence while one motor is starting-up, the
starting of the other motors is inhibited.

3. Preconfigurations
The 630 series IEDs are offered with optional
factory-made preconfigurations for various
applications. The preconfigurations
contribute to faster commissioning and less
engineering of the IED. The
preconfigurations include default
functionality typically needed for a specific
application. Each preconfiguration is
adaptable using the Protection and Control
IED Manager PCM600. By adapting the
preconfiguration the IED can be configured
to suit the particular application.
The adaptation of the preconfiguration may
include adding or removing of protection,
control and other functions according to the
specific application, changing of the default
parameter settings, configuration of the
default alarms and event recorder settings
including the texts shown in the HMI,
configuration of the LEDs and function
buttons, and adaptation of the default single-
line diagram.
In addition, the adaptation of the
preconfiguration always includes
communication engineering to configure the
communication according to the functionality
of the IED. The communication engineering
is done using the communication
configuration function of PCM600.
If none of the offered
preconfigurations fulfill the
needs of the intended area of
application, 630 series IEDs
can also be ordered without
any preconfiguration. In this
case the IED needs to be
configured from the ground
up.

4. Protection functions
REM630 offers all the functionality needed to
manage motor starts and normal drive
operations also including protection and fault
clearance in abnormal situations. The motor
management IED features motor run-up time
supervision, locked rotor protection and
protection against too frequent motor starts.
Furthermore, the IED offers thermal overload
protection, phase unbalance protection,
stabilized differential protection for motors,
high-impedance or flux-balance-based
protection, three-phase directional overpower
protection, underexcitation protection, load-
based motor jam protection, loss of load
supervision, and phase-reversal protection.
REM630 also incorporates non-directional
and directional earth-fault protection, rotor
earth-fault protection and back-up
overcurrent protection. The IED also offers
optional negative and positive phase
sequence overvoltage protection, positive
phase sequence undervoltage protection,
underfrequency and overfrequency protection.
In certain motor drives of special importance
there must be a possibility to override the
motor thermal overload protection to perform
an emergency start of a hot motor. To enable
an emergency hot start, REM630 offers a
forced start feature.

5. Control
The IED incorporates local and remote
control functions. The IED offers a number of
freely assignable binary inputs/outputs and
logic circuits for establishing bay control and
interlocking functions for circuit breakers and
motor operated switch-disconnectors. The
IED supports both single and double busbar
substation busbar layouts. The number of
controllable primary apparatuses depends on
the number of available inputs and outputs in
the selected configuration. Besides
conventional hardwired signaling also
GOOSE messaging according to IEC
61850-8-1 can be used for signal interchange
between IEDs to obtain required interlockings.
6. Measurement
The IED continuously measures the phase
currents, the symmetrical components of the
currents and the residual current. The IED
also measures phase and phase-to-phase
voltages, symmetrical components of the
voltages and the residual voltage. In addition,
the IED monitors active and reactive power,
power demand value over a user-selectable
pre-set time frames as well as cumulative
active and reactive energy of both directions.
Line frequency, the thermal overload of the
protected object, and the phase unbalance
value based on the ratio between the
negative sequence and positive sequence
current are also calculated. Cumulative and
averaging calculations utilize the non-volatile
memory available in the IED. Calculated
values are also obtained from the protection
and condition monitoring functions of the IED.
The values measured are accessed locally via
the front-panel user interface of the IED or
remotely via the communication interface of
the IED. The values are also accessed locally
or remotely using the web-browser based
user interface.
7. Disturbance recorder
The IED is provided with a disturbance
recorder featuring up to 40 analog and 64
binary signal channels. The analog channels
can be set to record the waveform of the
currents and voltage measured. The analog
channels can be set to trigger the recording
when the measured value falls below or
exceeds the set values. The binary signal
channels can be set to start a recording on
the rising or the falling edge of the binary
signal. The binary channels are set to record
external or internal IED signals, for example
the start or operate signals of the protection
functions, or external blocking or control
signals. Binary IED signals such as a
protection start or trip signal, or an external
IED control signal over a binary input can be
set to trigger the recording. In addition, the
disturbance recorder settings include pre- and
post triggering times.
The disturbance recorder can store up to 100
recordings. The number of recordings may
vary depending on the length of the
recording and the number of signals
included. The disturbance recorder controls
the Start and Trip LEDs on the front-panel
user interface. The operation of the LEDs is
fully configurable enabling activation when
one or several criteria, that is, protection
function starting or tripping, are fulfilled.
The recorded information is stored in a non-
volatile memory and can be uploaded for
subsequent fault analysis.
8. Event log
The IED features an event log which enables
logging of event information. The event log
can be configured to log information
according to user pre-defined criteria
including IED signals. To collect sequence-of-
events (SoE) information, the IED
incorporates a non-volatile memory with a
Motor Protection and Control 1MRS756977 D
REM630
Product version: 1.1 Issued: 2011-05-18
ABB 11

capacity of storing 1000 events with
associated time stamps and user definable
event texts. The non-volatile memory retains
its data also in case the IED temporarily loses
its auxiliary supply. The event log facilitates
detailed pre- and post-fault analyses of faults
and disturbances.
The SoE information can be accessed locally
via the user interface on the IED front panel
or remotely via the communication interface
of the IED. The information can further be
accessed, either locally or remotely, using the
web-browser based user interface.
The logging of communication events is
determined by the used communication
protocol and the communication engineering.
The communication events are automatically
sent to station automation and SCADA
systems once the required communication
engineering has been done.
9. Disturbance report
The disturbance report includes information
collected during the fault situation. The
report includes general information such as
recording time, pre-fault time and post fault
time. Further, the report includes pre-fault
magnitude, pre-fault angle, fault magnitude
and fault angle trip values. By default, the
disturbance reports are stored in a non-
volatile memory. The numerical disturbance
report can be accessed via the local front
panel user interface. A more comprehensive
disturbance report with waveforms is
available using PCM600.
10. Circuit-breaker
monitoring
The condition monitoring functions of the
IED constantly monitors the performance and
the condition of the circuit breaker. The
monitoring comprises the spring charging
time, SF6 gas pressure, the travel-time,
operation counter, accumulated energy
calculator, circuit-breaker life estimator and
the inactivity time of the circuit breaker.
The monitoring functions provide operational
circuit breaker history data, which can be
used for scheduling preventive circuit breaker
maintenance.
11. Trip-circuit
supervision
The trip-circuit supervision continuously
monitors the availability and operability of
the trip circuit. It provides open-circuit
monitoring both when the circuit breaker is
in its closed and in its open position. It also
detects loss of circuit-breaker control voltage.
12. Self-supervision
The IED’s built-in self-supervision system
continuously monitors the state of the IED
hardware and the operation of the IED
software. Any fault or malfunction detected is
used for alerting the operator.
Self-supervision events are saved into an
internal event list which can be accessed
locally via the user interface on the IED front
panel. The event list can also be accessed
using the web-browser based user interface
or PCM600.
13. Fuse failure
supervision
The fuse failure supervision detects failures
between the voltage measurement circuit and
Motor Protection and Control 1MRS756977 D
REM630
Product version: 1.1 Issued: 2011-05-18
12 ABB

the IED. The failures are detected by the
negative-sequence based algorithm or by the
delta voltage and delta current algorithm.
Upon the detection of a failure the fuse
failure supervision function activates an alarm
and blocks voltage-dependent protection
functions from unintended operation.
14. Current circuit
supervision
Current circuit supervision is used for
detecting faults in the current transformer
secondary circuits. On detecting of a fault the
current circuit supervision function can also
activate an alarm LED and block certain
protection functions to avoid unintended
operation. The current circuit supervision
function calculates the sum of the phase
currents and compares the sum with the
measured single reference current from a
core balance current transformer or from
another set of phase current transformers.
15. Access control
To protect the IED from unauthorized access
and to maintain information integrity, the IED
is provided with an authentication system
including user management. Using the IED
User Management tool in the Protection and
Control IED Manager PCM600, an individual
password is assigned to each user by the
administrator. Further, the user name is
associated to one or more of the four
available user groups: System Operator,
Protection Engineer, Design Engineer and
User Administrator. The user group
association for each individual user enables
the use of the IED according to the profile of
the user group.
16. Inputs and outputs
The IED is equipped with three phase-current
inputs and two residual-current inputs for
earth-fault protection. The IED always
includes one residual voltage input for
directional earth-fault protection or residual
voltage protection. Further, the IED includes
three phase-voltage inputs for overvoltage,
undervoltage and directional overcurrent
protection and other voltage based protection
functions.
The phase-current inputs are rated 1/5 A. The
IED is equipped with two alternative residual-
current inputs, that is 1/5 A or 0.1/0.5 A. The
0.1/0.5 A input is normally used in
applications requiring sensitive earth-fault
protection and featuring a core-balance
current transformer.
The three phase-voltage inputs, for either
phase-to-phase voltages or phase-to-earth
voltages, and the residual-voltage input cover
the rated voltages 100 V, 110 V, 115 V and
120 V. The rated values of the current and
voltage inputs are selected in the IED software.
In addition, the binary input thresholds are
selected by adjusting the IED’s parameter
settings. The threshold voltage can be set
separately for each binary input.
There is also an optional RTD/mA module
with 8 RTD/mA inputs and 4 mA outputs.
The optional RTD/mA module facilitates the
measurement of up to eight analog signals
via the RTD or mA inputs and provides four
mA outputs. The RTD and mA inputs can for
instance be used for temperature
measurement of motor bearings and stator
windings, thus extending the functionality of
the thermal overload protection and
preventing premature aging of the motor
windings. Furthermore, the RTD and mA
inputs can be used for measuring the ambient
air or cooling media temperature. The RTD
and mA inputs can be used for supervision of
analog mA signals provided by external
transducers. The RTD/mA inputs can be
alternatively used also as resistance input or
Motor Protection and Control 1MRS756977 D
REM630
Product version: 1.1 Issued: 2011-05-18
ABB 13

as an input for voltage transducer. The RTD/
mA module enables the use of the
multipurpose protection functions. These
protection functions can be used for tripping
and alarm purposes based on RTD/mA
measuring data, or analog values
communicated via GOOSE messaging. The
mA outputs can be used for transferring
freely selectable measured or calculated
analog values to devices provided with mA
input capabilities.
The enhanced scalability of the 6U variant
IEDs are intended for optimized medium
voltage metal-clad switchgear applications
where additional binary inputs and outputs
are often required.
All binary input and output contacts are
freely configurable using the signal matrix of
the application configuration function in
PCM600.
Please refer to the Input/output overview
tables, the selection and ordering data and
the terminal diagrams for more detailed
information about the inputs and outputs.

17. Communication
The IED supports the IEC 61850 substation
automation standard including horizontal
GOOSE communication as well as the well-
established DNP3 (TCP/IP) and IEC
60870-5-103 protocols. All operational
information and controls are available
through these protocols.
Seamless connectivity to industrial
automation systems is achieved with the
Station Automation COM600 device using the
OPC Server/Client technology. COM600
works as a gateway between the Distributed
Control System (DCS) and the bay level IEDs
enabling sending of monitoring data and
receiving of power distribution process
control commands.
Disturbance files are accessed using the IEC
61850 or IEC 60870-5-103 protocols.
Disturbance files are also available to any
Ethernet based application in the standard
COMTRADE format. The IED can send binary
signals to other IEDs (so called horizontal
communication) using the IEC 61850-8-1
GOOSE (Generic Object Oriented Substation
Event) profile. Binary GOOSE messaging can,
for example, be employed for protection and
interlocking-based protection schemes. The
IED meets the GOOSE performance
requirements for tripping applications in
distribution substations, as defined by the
IEC 61850 standard. Further, the IED
supports the sending and receiving of analog
values using GOOSE messaging. Analog
GOOSE messaging enables fast transfer of
analog measurement values over the station
bus, thus facilitating for example sharing of
RTD input values, such as surrounding
temperature values, to other IED
applications. The IED interoperates with
other IEC 61850 compliant IEDs, tools and
systems and simultaneously reports events to
five different clients on the IEC 61850 station
bus. For a system using DNP3 over TCP/IP,
events can be sent to four different masters.
For systems using IEC 60870-5-103 IED can
be connected to one master in a station bus
with star-topology.
All communication connectors, except for the
front port connector, are placed on integrated
communication modules. The IED is
connected to Ethernet-based communication
systems via the RJ-45 connector (10/100BASE-
TX) or the fibre-optic multimode LC
connector (100BASE-FX).

IEC 60870-5-103 is available from optical
serial port where it is possible to use serial
glass fibre (ST connector) or serial plastic
fibre (snap-in connector).
The IED supports SNTP, DNP3 and IRIG-B
time synchronization methods with a time-
stamping resolution of 1 ms.
The IED supports the following time
synchronization methods with a
timestamping resolution of 1 ms:
Ethernet communication based:
• SNTP (simple network time protocol)
• DNP3
With special time synchronization wiring:
• IRIG-B (Inter-Range Instrumentation Group
- Time Code Format B)
IEC 60870-5-103 serial communication has a
time-stamping resolution of 10 ms.
