Line Differential Protection and Control
RED615
Product version: 4.0

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 radial, looped
and meshed distribution networks with or without
distributed power generation. The RED615s
communicate between substations over a fibre-
optic link or a galvanic pilot wire connection.
RED615 is a member of ABB's Relion
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 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.

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,

2. Standard configurations

RED615 is available in three alternative standard
configurations. The standard signal configuration
can be altered by means of the graphical signal
matrix or the graphical application functionality of
the Protection and Control IED Manager PCM600.
Further, the application configuration functionality
of PCM600 supports the creation of multi-layer
logic functions utilizing 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.
