Abstract :
The need for improved standardization procedures for use on different types of partial discharge (PD) measuring systems is discussed. This requirement is examined using recording and processing data of complex PD signals obtained from in-service electrical apparatus. It is concluded that more fundamental knowledge of the PD mechanisms must be gained before any significant changes in existing calibration procedures can be made
