This paper presents a solution of a well-known problem in electrical energy distribution: the detection of partial discharges in a distribution system also used for communication (such as power control signals). We show the inconveniences of the classical approach (energy thresholding) and we present the results of a new approach, based on the projection of the signals in a multidimensional phase space, followed by a Hough transform-based analysis. Index Terms — electrical fault, partial discharge, Hough transform, phase diagram, phase space trajectory.
