What is the overvoltage start-up method for relay protection
To protect the relay from inductive fly back energy, a diode is placed across the load. Over voltage protection is used to protect the synchronous Generator/transformer/alternator form high voltage. Over voltage relay is an electrical protection device which is used for prevention of exceeding system voltage and operated after crossing pre set value of voltage and time then a tripping signal is provided to the circuit breaker tripping coil.
