Abstract
The problem of the interpretation of partial discharge (PD) measurements is approached by means of the shape analysis of PD amplitude distributions. Experimental cumulative PD distributions, detected insulation systems of HV rotating machine stator windings, are plotted on a Weibull graph in order to identify multiple PD sources. Examples of the application of PD distribution shape analysis as a diagnostic tool for AC HV stator insulation systems are presented and discussed. The calibration procedure and the significance of average parameters for degradation inference are reviewed. >
