Relay Protection Function of Electronic Systems
A protective relay is an intelligent device that senses abnormal electrical conditions, such as overcurrent, under-voltage, or frequency deviations. It initiates the operation of circuit breakers to isolate the affected section. This prevents damage to equipment, reduces downtime, and safeguards. Every electrical power system, whether a small industrial plant or a large utility grid – faces the constant threat of faults: short circuits, overloads, voltage sags, and equipment failures.
