TLDR
In this paper, the authors collected this knowledge and presented it as a coherent study, including the behaviour detection and measurement of discharges, the choice of detection method and procedure, the location of discharging and discharge detection in practice.Abstract:
Electrical discharges that do not completely bridge the electrodes are called partial discharges Although small, these discharges have been known for more than fifty years to cause progressive deterioration Since 1945 the use of new high voltage dielectrics has required the use of sophisticated detection techniques Discharge detection has grown into an indispensible tool for the evaluation of modern insulation The subject has received little attention in books on high voltage techniques although a good deal is scattered in various papers and reports The object of this book is to collect this knowledge and present it as a coherent study Topics covered include the behaviour detection and measurement of discharges, the choice of detection method and procedure, the location of discharges and discharge detection in practiceread more

The theory and measurement of partial discharge transients
TL;DR: In this paper, a theoretical approach to partial discharge transients is presented based on the relationship between the charge induced on the measurement electrode by those created in the interelectrode volume during partial discharge activity.
