master Trip relay 86 is the main tripping relay in the relay
protection scheme.It is actually tripping the breaker
poles.It acts because of the stimuli from any of the
protection relays.It's tripping coils are related with the
actuators from different relays.For example Directional
overcurrent relays and earth fault relays
