A protection relay is an intelligent device used to monitor electrical parameters such as current, voltage, frequency, and phase angle. When it detects abnormal conditions—such as overcurrent, short circuit, or voltage instability—it sends a trip signal to the circuit breaker, isolating the faulted section from the rest of the system.
