Dc Failure Relay Working. (ter.13,14 & 15) relay 2 0/p : the field failure relay, when used in series with the field circuit, ensures that no power is supplied to the armature unless field circuit is complete. this failure may be caused by the failure of the primary relays, by the failure of current transformers (cts) or potential transformers (pts) providing input to the primary relays, by the failure of the station battery or by the failure of the circuit breaker. • the function of protective relaying is to cause the prompt removal from service of an element of a power system when it. 8&9) relay 1 0/p : An ungrounded dc system is used to control the supply of protection systems, control panels, communication, and other networking devices. in the event of a field failure, the relay contacts open, allowing the main contactor to drop out and isolate the motor.
