A protective relay is an electrical device used to detect and isolate faults in a power system. It is a critical component of a power system protection scheme, and its main function is to trip or open the circuit breaker to isolate the faulty section of the power system when a fault occurs. Under normal operating conditions. Differential Protection: This is a unit-type protection scheme that works on the principle of comparing the currents entering and leaving a protected zone. A fault that results from excessive current causing a short circuit. Protective relay is an electrical device designed to initiate isolation of a part of an electrical installation, or to operate an alarm signal, in the event of an abnormal condition or a fault.
