摘要：Partial discharge is an important phenomenon to be considered while studying insulation failure. AnalysingPD characteristics and the detection of PD activity will help in improving the performance of insulator. In high voltage powersystem it is necessary to monitor the PD activity inside an insulator continuously. As the applied voltage increases the PDactivity increases as theelectric stress across the void becomes more than the electric stress across an equivalent distance ofdielectric [1]. The deterioration depends on the applied voltage and the number of discharge [2]. In this work an electriccircuit model of an epoxy resin with void of cylindrical shape is considered for realization of partial discharge activity insidethe insulator with the application of high voltage using MATLAB Simulink environment. The results obtained with variationin the parameters of the void such as radius, height and volume of the cylindrical void as an impurity is analysed.
