2.1
Overview
REU611 is a voltage protection relay preconfigured for voltage and frequency-based
protection in utility substations and industrial power systems. The relay is used for a
wide variety of applications, including busbar, power transformer, motor and
capacitor bank applications.
REU611 is a member of ABB’s Relion
®
product family and part of the 611 protection
and control product series. The 611 series relays are characterized by their
compactness and withdrawable-unit design.
The 611 series offers simplified yet powerful functionality for most applications.
Once the application-specific parameter set has been entered, the installed protection
relay is ready to be put into service. The further addition of communication
functionality and interoperability between substation automation devices offered by
the IEC 61850 standard adds flexibility and value to end users as well as electrical
system manufacturers.
The 611 series relays fully support the IEC 61850 standard for communication and
interoperability of substation automation devices, including fast GOOSE (Generic
Object Oriented Substation Event) messaging, and can now also benefit from the
extended interoperability provided by Edition 2 of the standard. The relays further
support the parallel redundancy protocol (PRP) and the high-availability seamless
redundancy (HSR) protocol. The 611 series relays are able to use IEC 61850 and
Modbus® communication protocols simultaneously.
