Feeder Protection and Control REF615

REF615 is a dedicated feeder protection IED perfectly aligned for the protection, control, measurement and supervision of utility substations and industrial power systems. Re-engineered from the ground up, the 615 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability of substation automation devices.

REF615 provides main protection for overhead lines, cable feeders and busbar systems of distribution substations. It fits both isolated neutral networks and networks with resistance or impedance earthed neutrals. As of now, the REF615 suite consists of six standard configurations to suit your current and forthcoming feeder protection requirements.

The IEC 61850 implementation in REF615 also includes fast horizontal communication over the station bus. By means of this so called GOOSE communication the REF615 IEDs of the incoming and outgoing feeders of a substation can co-operate to form a stable, reliable and high-speed blocking based busbar protection. REF615 also supports the industry standard Modbus protocol, DNP3 and IEC 60870-5-103.

Due to the standard configurations of REF615 for the protection of feeders, the IED can be rapidly set up and commissioned, once it has been given the application-specific settings.
