This paper presents an experimental test bench for generating disturbances in a transformer to validate power transformer differential protection methods. Introduction The differential protection scheme can be used to protect both the primary and secondary windings of a three-phase transformer against earth faults and phase-to-phase faults. The three-phase fault detection and protection system was designed to distinguish the type of fault that occurs in the power system, improved by the combination of Arduino and the current sensor. A relay that operates or picks up when its current xceeds a predetermined value (setting value) is called Over-current Relay.
The fact that the instantaneous power varies with time explains why some single phase mo-tor driven appliances such as refrigerators, which are fed from single phase supply experience vibration, and
