Title :
The interpretation of partial electrical discharge measurements with insulation damage and ageing
Author_Institution :

Abstract :
The author discusses partial discharge (PD) measurements with insulation damage and ageing, and presents evidence of various stages of solid dielectric deterioration. It is shown that the effect of these processes on measurements is demonstrated. The effects of PD activity within internal voids or cavities caused by delamination can produce acidic by-products, which then affect the surface conductivity. An attempt is made to identify processes that can cause confusion in the interpretation of results and propose an engineering option
