Location of partial discharges fault in transformer winding

Frequency response analysis can be used to examine distortion fault in transformer windings,but can't perform partial discharge Location. Based on frequency response analysis, the simulative circuit of transformer's winding was analyzed in this paper.According to the pure capacitive characteristic in current frequency range in transformer winding,a new method was given to realize locate the partial discharges fault in transformer winding.The method is proved to be effective by simulative experimentation.
