Protection Relay Tripping Circuit
The protection relay tripping circuit refers to the critical electrical control loop that executes trip/close commands from protective relays to circuit breakers, ensuring rapid fault isolation in power
What is a Master Trip (ANSI Code 86) Relay?
Master trip relay is a contact multiplication or an Auxiliary relay, which operates on the command from Multiple protection relays and gives a Single Command to the Breaker Trip Coil.
