How to test Trip Circuit Supervision Relay 95 Connection JRV 911

Hello friends in this Video I am explaining trip circuit supervision relay of JRV 911 of JVS make .

What is Trip Circuit Supervision Relay?

The trip circuit supervision relay always monitors the healthiness of the trip circuit including a connected trip coil of the CB. Tripping or isolation of CB is the most important part of power system protection. Always 02 nos. trip circuits are used in the CB for system redundancy.

Due to the failure of the trip coil or any discrepancy in the trip circuit, the CB will not operate even after receiving the trip signal from the protection relay. A separate relay is installed in the tripping circuit to monitor or supervise the healthiness of the trip circuit. If the supervision relay is operated or triggered, it should attend immediately by Protection Engineer.
