Overcurrent Relays These are protective relays used in medium and high-voltage systems. They detect abnormal current flow and send a trip signal to breakers. Best for short-circuit protection where no intentional. A protective relay is a compact and self-contained switchgear that trips a circuit breaker when a fault is detected for conditions such as overcurrent, overvoltage, over- and under-frequency, and reverse power flow.
