Algorithm to Calculate the Partial Discharge Response in a Transformer Winding

The Detection of the location of partial discharge in the windings of power transformers has always been considered a challenging task because of the convoluted structure of the winding. There are several methods proposed for the localization of partial discharge in the transformer winding. In this paper, we have concluded a detailed study on a generalized algorithm to compute the response of a partial discharge in a winding of a transformer. The algorithm for two separate winding sections that are along and across the winding is computed. A correlation method is used to compare the responses of the test signal and an arbitrary signal. A response is calculated as a current response at the winding neutral terminal.
