Description

REB611 is a dedicated busbar protection relay for phase

segregated short-circuit protection, control, and supervision of

single busbars. REB611 is intended for use in high-impedance

based applications within utility substations and industrial

power systems. In addition, the protection relay can be utilized

in restricted earth-fault and residual earth-fault applications for

the protection of generators, motors, transformers and reactors.

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.
