Transformer Protection Relay

The transformer protection relays are designed to be the main protection and control IED for two and three winding power transformers, including auto-transformers and special railway transformers. The protection relays provide a variety of versatile protection functions along with the main transformer differential protection(87T), such as restricted earth-fault protection(87N), 3ph, Io and I2 overcurrent protection(50/51, 50/51N, 46), overload protection(49), breaker failure protection(50BF). Voltage and frequency related protection functions as 27, 59, 24, 47, 81O, 81U can also be integrated if required. Because of the implemented control, measuring and monitoring function, the IED can also be used as a bay control unit.
