Abstract

Provided is a method of accurately detecting the location of a partial discharge in a power device. For this purpose, the present invention measures sequential positions of arrival of partial discharge signals and the differences in the time of arrival between the partial discharge signals with respect to a plurality of partial discharge sensors installed on the outside surface of a power device, divides the power device into a plurality of spatial sections, determines a spatial section where the location of a partial discharge is present using the sequential positions of arrival of the partial discharge signals, calculates the representative location value of the determined spatial section, and determines compensation values for the differences in the time of arrival to be applied with respect to the respective spatial sections.
