Abstract: An important tool for improving the reliability of high voltage (HV) insulation systems are partial discharge (PD) measurements. Partial Discharge (PD) that damages insulation by gradual erosion is major source of insulation failure. In electrical engineering, partial discharge (PD) is a localized dielectric breakdown of a small portion of a solid or fluid electrical insulation system under high voltage stress, which does not bridge the space between two conductors. So, an important tool for improving the reliability of HV insulation systems are partial discharge (PD) measurements. Accurate simulating of PD is more important for insulation study. In this paper, the mechanism of PD has been simulated by using MATLAB simulink.
