The SPAG 331 C numerical generator protection relay applies for the protection of small and medium sized power generators and their prime movers. The generator protection unit is used in small hydro-power plants, thermal power stations and other stationary power plants. Further, the relay is approved for use in marine and off-shore applications. The generator protection relays SPAG 331 C is often used for the protection of generators connected to the network by means of a generator transformer.
