ABSTRACT
This paper presents the results of electric field and potential distributions simulation along surface of silicone rubber polymer insulators. Finite element method (FEM) is adopted for this paper. Identification of the electrical field and the potential distributions at the dielectric insulation has always been important; The water droplets increase the electric field strength at the insulator surface because of their high permittivity and conductivity, at first the results of water droplets existing on the surface of silicone rubber materials has been investigated and electric field distribution along the surface are shown. Then Different Thickness and conductivity of pollution layer on polymer insulator has been considered and electrical field distribution has been analyzed.
