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.
