Abstract

The aim of this paper is to compare different partial discharge (PD) charge estimation methods for PD cable measurements. The paper covers the mathematical foundation behind the different presented methods, and explores the limits of each method regarding the associated maximum charge estimation errors in PD cable measurements. The results are focused on long cables where large PD pulse distortions are present and therefore, the measured pulses differ significantly from the calibrator ones. Each proposed method is analyzed, and finally, limitations of each method are discussed.
