Abstract

This paper presents electric field distribution and voltage (potential) distribution along with the 66 kV polymer insulator at the clean surface condition to study the effect of corona ring. Three parameters: horizontal distance from end fitting of corona ring (R), vertical distance (H) and diameter of ring (r) are taken to optimize the insulator design that may minimize the electrical field. Since corona rings reduce the electric field, therefore, the electrical field profiles with and without the ring are compared to adjust and finally select the optimum design parameters. The electric field estimation is performed using numerical method, i.e. finite element method (FEM).
