Learn Basic Electrical Engineering, Protection Switch gear, relays, Online Calculator, Electrical - Get More Electrical Knowledge with easy English In static relays, the measurement is performed by electronic/magnetic/optical or other components without mechanical motion. A relay (protective) is a device that detects the fault and initiates the operation of the circuit breaker to isolate the defective element from the rest of the system. Here the fixed coil is fed from the circuit to be protected. The relay operates when the ratio V/I i.e., impedance is less than a predetermined value. or it may be the output of a transducer or it may be combination of various signals. Differential relays are very sensitive to the faults occurred within the zone of protection but they are least sensitive to the faults that occur outside the protected zone. Electromagnetic Relay.
