Applications - Feeder Protection

From generation via transmission and distribution down to the load. Feeder protection relays protect the entire power chain throughout different voltage levels.

Modern communication systems are the basis for economical and efficient application of your operating components. We are offering nearly every communication network various protocols like Modbus® RTU, Modbus® TCP, Profibus® DP, IEC 60870-5-103 and IEC 61850.
