Transformer digital protection system is one of the protection units used as Restricted earth Fault protection which initially needs to be operate as fast and reliable protection Scheme for major Equipments. Improvement in performance of REF relay during transients and internal Fault occurs in transformer internal winding, and its need to be improve through proposed Scheme has to be implement in the Transformer Protection, thus Transformer Protection system which typically a fast response and is prone to mal operation of the relay in these paper represent through Simulation in MATLAB.

Current Transformer (CT), High Voltage winding (HV), Low Voltage winding (LV), Earth Fault (EF), Restricted Earth Fault (REF).
