In this paper, the electric field in different types of ZnO surge arresters has been investigated by means of finite element modeling using COMSOL Multiphysics. Both conventional and novel built-in-bushing type arresters were studied.

Electric field modeling helps designers consider important factors affecting the maximum field intensity in the arrester, avoiding damages to the arrester insulating system that brings it to a premature failure.
