1. Description
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 withdrawable-unit 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
60870-5-103, Modbus®and DNP3.
2. Standard
configuration
REM615 is available in three alternative
standard configurations. The standard signal
configuration can be altered by means of the
graphical signal matrix or the optional
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.

3. Protections functions
The IED offers all the functionality needed to
manage motor starts and normal operation,
also including protection and fault clearance
in abnormal situations. The main features of
the IED include thermal overload protection,
motor start-up time supervision, locked rotor
protection and protection against too
frequent motor starts. The IED also
incorporates non-directional earth-fault
protection, negative phase-sequence current
unbalance protection and backup overcurrent
protection. Furthermore, the IED offers motor
running stall protection, loss-of-load
supervision and phase-reversal protection.
Standard configurations B and C additionally
offer directional earth-fault protection, three
phase undervoltage protection, negative
phase-sequence overvoltage and positive
sequence undervoltage protection. Further,
the B and C configurations offer frequency
protection including overfrequency,
underfrequency and rate-of-change frequency
protection modes.
The RTD/mA module offered as an option for
standard configurations A and B enable the
use of the optional multipurpose protection
function which can be used for tripping and
alarm purposes using RTD/mA measuring
data or analog values via GOOSE messages.
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, REM615 offers a
forced start execution feature.
Enhanced with optional hardware and
software, the IED also features three light
detection channels for arc fault protection of
the circuit breaker, busbar and cable
compartment of metal-enclosed indoor
switchgear.
The arc-fault protection sensor interface is
available on the optional communication
module. Fast tripping increases personnel
safety and limits switchgear damage, should
an arc fault occur.

4. Application
REM615 constitutes main protection for
asynchronous motors and the associated
drives. Typically, the motor IED is used with
circuit-breaker or contactor controlled HV
motors, and contactor controlled medium
sized and large LV motors in a variety of
drives, such as pumps and conveyors,
crushers and choppers, mixers and agitators,
fans and aerators.
The motor IED is thoroughly adapted for earth-
fault protection. Using cable current
transformers sensitive and reliable earth-fault
protection can be achieved. Phase current
transformers in Holmgreen (summation)
connection can also be used for earth-fault
protection. In that case possible unwanted
operations of the earth-fault protection at
motor start-up due to CT saturation can be
prevented using the IED's internal
interlocking features or a suitable stabilizing
resistor in the common neutral return.
The optional RTD/mA module offered for
standard configurations A and B facilitates
the measurement of up to eight analog
signals via the six RTD inputs or the two mA
inputs using transducers. The RTD and mA
inputs can be used for temperature
monitoring of motor bearings and stator
windings, thus expanding the functionality of
the thermal overload protection and
preventing premature aging of the motor.

Furthermore, the RTD/mA inputs can be used
for measuring the ambient cooling air
temperature. The analog temperature values
can, if required, be sent to other IEDs using
analog horizontal GOOSE messaging.
Temperature values can also, vice versa, be
received from other IEDs over the station
bus, thus increasing the extent of relevant
information.
