Line Differential Protection and Control
RED615
Product version: 2.0

1. Description

RED615 is a phase-segregated two-end line
differential protection and control IED
(intelligent electronic device) designed for
utility and industrial power systems,
including looped and meshed distribution
networks with or without decentralized
power generation. RED615 is a member of
®
ABB's Relion family and its 615 protection
and control product series. Re-engineered
from the ground up, the 615 series has been
guided by the IEC 61850 standard for
communication and interoperability of
substation automation equipment.
The IED provides unit type main protection
for overhead lines and cable feeders in
distribution networks. The IED also features
current-based protection functions for remote
back-up for down-stream protection IEDs and
local back-up for the line differential main
protection. Further, standard configurations B
and C also include earth-fault protection.

Description
Line differential protection
Line differential protection with directional earth-fault protection
Line differential protection with non-directional earth-fault protection
The IED is adapted for the protection of
overhead line and cable feeders in isolated
neutral, resistance earthed, compensated
(impedance earthed) and solidly earthed
networks. Once the 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
configurations
The line differential protection and control
IED RED615 is available with three
alternative standard configurations.
