PROTECTION RELAYS

Power System protection is crucial part of power station and substations safety which use protection relays and circuit breakers to isolate faulty parts or zones within the plant including Generator zone, Motor zone, Feeder zone, Bus zone, Transformer zone and Transmission Lines zone. Hence a comprehensive testing of protection relays is very important in order to keep the power system stable and working properly.

EMC PARTNER offers a complete and extensive test solutions from one hand to conduct all conducted immunity impulse and insulation tests.
