Abstract

In this paper, we developed 3 dimensional Surface Charge Method which could calculate electric fields inside GIS with a small void in solid insulator or with a metal impurity. We find a metal impurity makes much more non-uniform electric field distribution inside GIS than a small void. We also find electric field is much more increased when a metal impurity is close to solid insulator surface at high voltage conductor.
