The Usage of Morphological filters in Process of Partial Discharge Activity Measurement

Abstract

Partial discharge activity signal de-noising by morphological filters is presented. Morphological filters have the advantage of preserving original useful signal waveform and they can efficiently remove noise pulses from signal corrupted by noise and acquired during partial discharge measurement on electric power devices. We analyze the efficiency of morphological filtering for different noise type occurring in environment where partial discharge activity is measured.
