Abstract

Abstract This article displayed the method of partial discharge (PD) measurement in high-voltage insulator and calibrating the effective element (capacitor) to enhance the PD signal. The cavity shapes were plate–plate, cylindrical and spherical inside the solid insulator. The proposed system enables from detecting the reverse and main discharge, respectively, through the rise and tail time of the pulses. PD that took place was bounded with internal cavities. Proteus simulator and Matlab simulation models were used to measure and display the PD signal. The results showed PD-calibrated waveforms and the voltage values across the cavity (V c). Finally, this work concluded that the spherical cavity shape gave a higher value of the calibrated capacitor and lower voltage across the cavity (V c) for both models.
