REF615 overview

Overview

REF615 is a dedicated feeder protection and control relay designed for the protection,
control, measurement and supervision of utility substations and industrial power systems
including radial, looped and meshed distribution networks with or without distributed
power generation. REF615 is a member of ABB's Relion
615 protection and control product series. The 615 series relays 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.
The relay provides main protection for overhead lines and cable feeders in distribution
networks. The relay is also used as back-up protection in applications, where an
independent and redundant protection system is required.
Depending on the chosen standard configuration, the relay is adapted for the protection of
overhead line and cable feeders in isolated neutral, resistance grounded, compensated and
solidly grounded networks. Once the standard configuration relay has been given the
application-specific settings, it can directly be put into service.
The 615 series relays support a range of communication protocols including IEC 61850
with Edition 2 support, process bus according to IEC 61850-9-2 LE, Modbus
DNP3.
