745 Transformer Protection System

Product Description

745Transformer Protection System

The 745 Transformer Protection System is a full featuredtransformer protection relay, suitable for application on small, medium, andlarge power transformers. The 745 can be applied on two-winding andthree-winding transformers. Uses multiple current and voltage inputs to provideprimary protection and back-up protection of transformers, includingdifferential, ground differential phase, neutral, and ground overcurrent,over-fluxing, and on-load tap changer.
