Due to Continues Demand for Electric Power many ideas are either to build new transmission lines or improve the existing lines to high capacity. Generally porcelain Insulators are being used since long time and from past few years porcelain are removed and in those places polymer Insulators are replaced because of their excellent pollution performances and other advantages such as easy to Install, can carry to long places easily, the main disadvantage of Composite Silicone Insulators is that the size of Insulator increase with increase in the rating and they are sensitive to electrical stresses. To examine these electrical stresses experiment were conducted earlier because in past there are no computational analysis, but now-a-days computing techniques are available and therefore the analysis of the electric filed is done using numerical method. This paper gives detail electric field distribution along the composite insulator under dry conditions with increase in voltage rating and also investigates the distribution of electric filed when a corona ring is connected to it.This analysis is performed using COULOMB 8.0-Field Design Analysis Software.
