1. Description
REF630 is a comprehensive feeder
management IED for protection, control,
measuring and supervision of utility and
industrial distribution substations. REF630 is
a member of ABB’s Relion®product family
and a part of its 630 protection and control
product series characterized by functional
scalability and flexible configurability.
REF630 also features necessary control
functions constituting an ideal solution for
feeder bay control.
The 630 series IEDs support the new IEC
61850 substation automation standard
including horizontal GOOSE communication
and the DNP3 communication protocol
offering seamless connectivity to station
automation and SCADA systems.
2. Application
REF630 provides main protection for
overhead lines and cable feeders of
distribution networks. The IED fits both
isolated neutral networks and networks with
resistance or impedance earthed neutral. Four
pre-defined configurations to match typical
feeder protection and control requirements
are available. The pre-defined configurations
can be used as such or easily adapted or
extended with freely selectable add-on
functions, by means of which the IED can be
fine-tuned to exactly satisfy the specific
requirements of your present application.

3. Preconfigurations
The 630 series IEDs are offered with optional
factory-made application preconfigurations.
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
the 630 series IEDs can also be ordered
without any preconfiguration. This option
enables full flexibility to configure the IED
from the ground up.

4. Protection functions
The IED offers selective short-circuit and
overcurrent protection including three-phase
non-directional overcurrent protection with
four independent stages, and three-phase
directional overcurrent protection with three
independent stages. In addition, the IED
includes three-phase current inrush detection
for blocking selected overcurrent protection
stages or temporarily increasing the setting
values. The included thermal overload
protection function uses thermal models of
overhead lines and cables. The negative-
sequence overcurrent protection, with two
independent stages, is used for phase-
unbalance protection. In addition, the IED
offers phase discontinuity protection.
Further, the IED features selective earth-fault
and cross country fault protection for isolated
neutral, and for resistance and/or impedance
earthed neutral systems including solidly
earthed neutral systems. The earth-fault
protection includes non-directional earth-fault
protection with three independent stages and
directional earth-fault protection with four
independent stages.
The included transient/intermittent earth-fault
protection is based on detection of earth-fault
transients related to continuous or
intermittent faults. Intermittent earth-fault is
special type of earth-fault encountered in
compensated networks with underground
cables. In solidly earthed or compensated
networks the transient earth-fault protection
function detects earth-faults with low fault
resistance. The residual overvoltage

protection, with three independent stages, is
used for earth-fault protection of the
substation bus and the incoming feeder, and
for back-up protection of the outgoing feeders.
The IED offers distance protection including
both circular (mho) and quadrilateral (quad)
zone characteristics, three independent zones
with separate reach settings for phase-to-
phase and phase-to-earth measuring elements
and two zones for controlling auto-reclosing
of circuit breakers. Further, the IED offers
automatic switch onto fault logic with voltage
and current based detection options.
The IED offers voltage protection functions
including three-phase undervoltage and
overvoltage protection with three
independent stages each, both with phase-to-
phase or phase-to-earth measurement. The
IED offers overfrequency, underfrequency
and rate-of-change of frequency protection to
be used in load shedding and network
restoration applications.
In addition the IED offers three-pole multi-
shot autoreclose functions for overhead line
feeders.
The IED incorporates breaker failure
protection for circuit breaker re-tripping or
back-up tripping for the upstream breaker.
