In this example, I've implemented differential protection in a 230/13.8 kV substation using •Transmission line •Bus bars •HV circuit breakers •CTs •87 ANSI number relay for transformer differential protection. As soon as a fault enters the zone of the differential relay, both side (HV & LV) breakers open up after receiving a tripping command from the relay.
