MVR-T216 https://www.deif.com/products/protection-relays/mvr-t216/ en Sat, 15 Aug 2026 23:06:04 GMT Active 835b666a-e2e7-4654-b6af-1fcb4b1daaee The MVR-T216 transformer protection offers easy-to-use differential protection together with overcurrent protection for both high and low voltage side of the transformer.

]]> The MVR-T216 transformer protection relay provides overcurrent protection for both low voltage and high voltage side of the transformer. In addition to that it offers earth fault protection, negative sequence overcurrent protection as well as two independent instances of restricted earth fault protection for utmost protection of the transformer.
