REF615 is a dedicated feeder protection relay perfectly aligned for the protection, measurement and supervision of utility substations and industrial power systems. Re-engineered from the ground up, REF615 has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability of substation automation devices.
The relay provides main protection for overhead lines, cable feeders and busbar systems of distribution substations. The feeder protection relay suits any radial distribution network and system earthing principle.
The IEC 61850 implementation in REF615 also includes fast horizontal relay-to-relay communication over the station bus. By means of this so called GOOSE communication the REF615 relays of the incoming and outgoing feeders of a substation can co-operate to form a stable, reliable and high-speed blocking based busbar protection.
Due to the ready-made adaptation of REF615 for the protection of feeders, the relay can be rapidly set up and commissioned, once it has been given the application-specific relay settings. If the relay needs to be adapted to the special requirements of the intended application, the flexibility of the relay allows the relay's standard signal configuration to be adjusted.
