Influence of Electric Field Distribution on 33kv Non-Ceramic Insulator with Different Shed Configurations using 3D Finite Element Method

Abstract

In last decade, influence of electric field (E-field) distribution is plays a major concern in estimating the service life of Non-cermaic insulators. One of the foremost troubles met by the utilities is the breakdown of insulator owing toward high electrical stress on end fittings. The present work is intended to focus on the impact of different shed configurations on 33kV Non-Ceramic insulators by 3-Dimensional (3D) Finite Element Method (FEM). Totally seven different shed configurations of 3D simulation studies is performed on 33kV non-ceramic insulators. Optimum result is obtained by alternate shed configured insulator and the first shed near to the metal end fittings. It is whispered that obtained results will be helpful to the utility and design engineers.
