Abstract
This paper investigates the simulation results of the electric field distributions along silicone rubber insulator surfaces with different designs and under different pollution conditions. The first model consists of four uniform sheds and the second model consists of five alternative sheds. In order to study the effects of different types of pollution layers like (sand, water-saturated sand, and nitrogen dioxide) on the electric field over the creepage distance with thickness 0.1 cm. the maximum electric fields in water-saturated sand 130 kV/m in the first model and 129 kV/m in the second model, in case of air with dry sand 110 kV/m in the first mode and 90 kV/m in the second model, in pure air 95 kV/m in the first model and 73 kV/m in the second model. According to the explosion ammonium nitrate, the maximum electric field in both models 220KV/m when the air is polluted with nitrogen dioxide and the maximum electric field in case the pollution layer in the insulator is 360 kV/m in the first model and 185 kV/m in the second model. (COMSOL multiphasic 5.5) software programs have been used for calculating and comparing different types of pollution based on the finite element method (FEM).
