Relay Testing is the process of inspecting, calibrating, and verifying protection relays to ensure they correctly detect faults and initiate circuit breaker operation within the specified time. Why is Relay Testing important? Relay testing ensures reliable fault detection, prevents unnecessary trips, protects electrical equipment, minimizes downtime, and improves overall power system safety and reliability. What types of relays do you test? We test numerical relays, electromechanical relays, static relays, overcurrent relays, earth fault relays, differential relays, distance relays, voltage relays, frequency relays, and transformer protection relays. What is the difference between primary and secondary injection testing? Secondary injection testing verifies relay operation by injecting simulated current and voltage directly into the relay, while primary injection testing applies high current through the complete protection circuit to verify CTs, relays, wiring, and circuit breaker operation together.
