Selection methods of partial discharge in insulation of power transformers Modelling of discharging processes in capacitive ignition systems with onepolar impulse

Abstract

In the paper analysis of selection methods of partial discharge measurement data is done. Analysis of pulse shape of partial discharge is made. Selection method with application of wavelet analysis is proposed. Required properties for a mother wavelet is formulated. Diagnostic of power equipment; power transformers; partial discharge; wavelet transform.
