Transformer Protection and Control
RET620
Product version: 2.0

1. Description

RET620 is a dedicated transformer IED perfectly aligned for
the protection, control, measurement and supervision of both
power and step-up transformers, including power generator-
transformer blocks, in utility and industrial power distribution
systems. RET620 is a member of ABB's Relion
and control product family and its 620 series. The 620 series
IEDs are characterized by their functional scalability and
withdrawable-unit design.
The 620 series has been designed to unleash the full potential
of the IEC 61850 standard for communication and
interoperability of substation automation devices.

2. Default configurations

The 620 series IEDs are configured with default
configurations, which can be used as examples of the 620
ABB
series engineering with different function blocks. The default
configurations are not aimed to be used as real end-user
applications. The end-users always need to create their own
application configuration with the configuration tool. However,
the default configuration can be used as a starting point by
® modifying it according to the requirements.
protection
RET620 is available with one default configuration. The
default 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. Furthermore, 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.
