Relay protection DC resistance test

Home / Relay protection DC resistance test

The insulation resistance test is completed in line with IEC 60255-27, i. The testing and verification of relay protection devices can be divided into four groups: Type tests are needed to prove that a protection relay meets the claimed specification and follows all relevant standards. Mechanical relays rely on an electromagnetic coil and movable contacts, whereas solid-state relays use semiconductor devices. 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.
