Analysis of insulation degradation in Insulators using Partial Discharge analysis

In Power system, the reliable power supply plays a vital role in Generation, Transmission and Distribution. It is necessary to facilitate uninterrupted Power supply by continuous monitoring of Power apparatus. In this regard, the monitoring and prevention of insulation failure becomes essential for uninterrupted functioning of power equipments. In this paper the deterioration of Insulation in Insulators is determined from the analysis of Partial Discharge signals. The Partial Discharge signals are produced by the localized ionization within electrical field. Hence the numerical analysis of Electric field can provide information about the Partial Discharges which is determined by using the Finite Element method.
