Abstract

Partial discharge (PD) degrades the quality of insulation systems, and its impact becomes even more severe with ageing. Several studies have revealed PD activity to be environmental and test factors dependent. Among the several test factors, the excitation frequency is of high significance, as it affects the PD behavior in a system. In this paper, the behavior of PD in epoxy-resin is investigated under different excitation frequencies. A 3D model of the insulation sample is created in COMSOL, and used alongside MATLAB software to simulate PD under very low and power frequencies (VLF and PF) respectively. From the phase-resolved PD distributions, it is evident that PD activities increases with increase in excitation frequencies and vice-versa.
