REB500 uses state-of-the art technology and delivers enhanced protection and communication performance. As part of the proven Relion series, it enables differential protection performance below one power cycle. With this flexibility, REB500 can protect various busbar configurations under all circumstances.

REB500 detects all bus and feeder faults for any type of system earthing, whether it is an isolated system or a solidly, low impedance or compensated earthed system. It operates selectively for all faults in the protected zone and maintains complete stability for faults outside the protected zone.

Digital, real-time communication technology has provided a platform for the development of a fully numerical, decentralized busbar and breaker-failure protection system. Dubbed REB 500, it is based on the concept of remote, bay-oriented data acquisition and preprocessing and is suitable for all kinds and sizes of substations.
