The T35, a member of the UR family of protection relays, is a 3-phase transformer relay, intended for primary protection of power transformers, with up to six windings/restraints. The T35 Transformer Management Relay is a perfect protection for multi-winding power transformers, where the windings are connected to more than one breaker such as in a breaker-and-a-half schemes, or to more than two breakers. Percent and instantaneous differential protections combined with phase time overcurrent elements and sixteen fully configurable universal comparators (FlexElements ), make a perfect protection package for primary and backup transformer protections. The relay is capable of protecting transformers with up to six windings/restraints.
