The SPAG 330 C numerical generator protection relay applies for the protection of small and medium sized power generators and their prime movers. The generator protection relay is used in small hydropower 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 relay SPAG 330 C is often used for the protection of directly connected generators with solidly earthed neutrals.
