Abstract
This paper analyzes the behavior of winding to ground fault in the single-phase transformer using experimental setup in laboratory level. The winding to ground fault in each voltage winding of the single-phase transformer is first obtained in order to analyze the behavior of the differential current of the transformer. For different winding voltages of the transformer, the calculated differential current of the transformer will be employed to analyze the behavior of winding fault to ground in the single-phase transformer using discrete wavelet transform (DWT) method. The coefficient comparison between high frequency component and low frequency component will be done in order to confirm the effectiveness of the applied technique in this study.
