ABB RET615 - Description

1. Description
RET615 is a dedicated transformer protection and
control IED (intelligent electronic device) for power
transformers, unit and step-up transformers
including power generator-transformer blocks in
utility and industry power distribution systems.
RET615 is a member of ABB’s Relion
®
product
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 designed to unleash the full potential of
the IEC 61850 standard for communication and
interoperability between substation automation
devices. Once the standard configuration 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
RET615 is available in eight 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.
