Measurement of partial discharge in solid dielectrics with a microprocessor-based system

The authors discuss briefly the basic aspects of partial discharge (PD) measuring techniques with special emphasis on the problem of detecting the amplitude of discharge pulses having transient decaying sinewave shapes. After a short account of the recent multichannel pulse-height analysis techniques of collected data and of the use of a computerized system for calculating multiple discharge parameters, a new digital system for PD measurement and computer data processing is presented. >
