ABB REB611 Busbar Protection Relay

DESCRIPTION

The REB611 is a specialized busbar protective relay for split-phase short-circuit protection, control and monitoring of single busbars.

The REB611 is suitable for high impedance based applications in utility substations and industrial power systems.

In addition, the relay can be used in restricted earth fault and residual earth fault applications to protect generators, motors, transformers and reactors.

The 611 series relays fully support the IEC 61850 standard for communication and interoperability of substation automation equipment.

This includes fast GOOSE (Generic Object Oriented Substation Event) messaging, and can now also benefit from the extended interoperability offered by version 2 of the standard.

The relays further support the Parallel Redundancy Protocol (PRP) and the High Availability Seamless Redundancy Protocol (HSR).

The 611 series relays can use both IEC 61850 and Modbus® communication protocols.

The REB611 is a member of the ABB Relion® product family and part of the 611 protection and control product family.

The 611 series relays are characterized by a compact and withdrawable unit design.

The 611 series offers simplified yet powerful functionality for most applications. After entering the application-specific parameter set, the installed relay is ready for operation.

The IEC 61850 standard further increases communication capabilities and interoperability between substation automation equipment, adding flexibility and value for end users and electrical system manufacturers.
