ABB REF615 IEC Feeder Protection And Control Relay

Description

The REF615 is a specialized feeder protection and control device designed for the protection, control, measurement, and monitoring of public and industrial distribution systems. It is capable of adapting to both solidly grounded and resistance or impedance grounded electrical grids. Additionally, utilizing advanced station-level communication capabilities, the REF615 can also be used for protection in ring or radial distribution networks. The protected grid includes multiple feeders and distributed generation.
