REU 610 Voltage Relay

The voltage protection relay is primary designed for the overvoltage protection of power system components, such as busbars, feeders, power transformers and capacitor batteries. The relay is also used for general power system earth-fault supervision. Further, the relay can be used for undervoltage protection of motors and overvoltage protection of capacitor batteries, for initialization of automatic busbar changeover, and for disconnecting small power units from the network in cases of network disturbance.

The voltage protection relay REU 610 supports a wide range of standard communication protocols, among them the IEC 61850, IEC 60870-5-103, Modbus, Profibus and DNP.
