1MRS756379 D
Issued: December 2007
Revision: D / 03 Mar 2009
1. Description
REF615, member of ABB’s 615 product
series, is a dedicated feeder protection IED
designed for the protection, measurement
and supervision of utility substations and
industrial power systems. Re-engineered from
the ground up, the IED has been guided by
the IEC 61850 standard for communication
and interoperability of substation automation
devices.
The IED provides main protection for over-
head lines and cable feeders in distribution
networks. The IED is also used as back-up
protection in applications, where an inde-
pendent and redundant protection system is
required.
Depending on the preconfiguration made,
the IED is adapted for the protection of
overhead line and cable feeders in isolated
neutral, resistance earthed, compensated and
solidly earthed networks. Once the standard
configuration IED has been given the appli-
cation-specific settings, it can directly be put
into service.
The 615 series IEDs support a range of com-
munication protocols including IEC 61850
with GOOSE messaging, IEC 60870-5-103,
Modbus® and DNP3.

1) Basic interlocking functionality: Closing of the circuit breaker can be enabled by a binary input signal. The actual
interlocking scheme is implemented outside the IED. The binary input serves as a “master interlocking input”
and when energized it will enable circuit breaker closing.
2) Extended interlocking functionality: The circuit breaker interlocking scheme is implemented in the IED
configuration, based on primary equipment position information (via binary inputs) and the logical functions
available. The signal matrrix tool of PCM600 can be used for modifying the interlocking scheme to suit your
application.

3. Protection functions
The IED offers directional and non-direc-
tional overcurrent and thermal overload
protection, directional and non-directional
earth-fault protection, sensitive earth-fault
protection, phase discontinuity protection,
transient/intermittent earth-fault protection,
overvoltage and undervoltage protection,
residual overvoltage protection, positive-se-
quence undervoltage and negative-sequence
overvoltage protection. In addition the IED
offers three-pole multi-shot auto-reclose func-
tions for overhead line feeders.
Enhanced with optional hardware and soft-
ware, the IED also features three light detec-
tion channels for arc fault protection of the
circuit breaker, busbar and cable compart-
ment of metal-enclosed indoor switchgear.
The arc-fault protection sensor interface is
available on the optional communication
module. Fast tripping increases personal
safety and limits material damage within the
switchgear in an arc fault situation.

4. Application
The feeder protection IED REF615 can be
supplied either with directional or nondi-
rectional earth-fault protection. Directional
earth-fault protection is mainly used in
isolated or compensated networks, whereas
non-directional earth-fault protection is in-
tended for directly or low impedance earthed
networks.
The standard configurations A and B offer di-
rectional earth-fault protection, if the outgo-
ing feeder includes phase current transform-
ers, a core-balance current transformer and
residual voltage measurement. The residual
current calculated from the phase currents
can be used for double (cross country) earth-
fault protection. The IED further features
transient/intermittent earth-fault protection.
The standard configurations C and D offer
non-directional earth-fault protection for out-
going feeders including phase current trans-

relevant options. In the incoming feeder bay, the protection functions not used are
uncoloured and indicated with a dashed block outline. The IEDs are equipped with
optional arc protection functions, enabling fast and selective arc protection throughout
the switchgear.

formers. The residual current for the earth-
fault protection is derived from the phase
currents. When applicable, the core-balance
current transformers can be used for meas-
uring the residual current, especially when
sensitive earth-fault protection is required.
The standard configurations E and F offer
directional earth-fault protection with phase
voltage and residual voltage measurement.
Further, the two standard configurations
include current circuit supervision and fuse
Fig. 6 Substation O/C and E/F protection using the standard configuration C or D with
relevant options. In the incoming feeder bay the unemployed protection functions are
uncoloured and indicated with a dashed block outline. The busbar protection is based
on the interlocking principle, where the start of the O/C protection of the outgoing feeder
sends a blocking signal to the instantaneous O/C stage of the incoming feeder. In the
absence of the blocking signal, the O/C protection of the incoming feeder will clear the
internal switchgear (busbar) fault.
failure supervision for incoming feeders
with busbar voltage measurement. Standard
configuration F offers in addition to standard
configuration E directional overcurrent pro-
tection, overvoltage and undervoltage pro-
tection, positive-sequence undervoltage and
negative-sequence overvoltage protection and
residual voltage protection.
