GE / ALSTOM 745 transformer protection system

The ALSTOM 745 transformer protection System is a full featured transformer protection relay, suitable for application on small, medium, and large power transformers. The 745 can be applied on two-winding and three-winding transformers. Uses multiple current and voltage inputs to provide primary protection and back-up protection of transformers, including differential, ground differential phase, neutral, and ground overcurrent, over-fluxing, and on-load tap changer.
