Abstract

A comprehensive review for the scattered phenomenon of energy absorption capabilities of ZnO varistors was presented in this paper. The pronounced and complex scattered phenomena were revealed according to experiments under varied test conditions. Those experiment phenomena were well explained by numerical simulations with microscopic circuit and heat transfer models of ZnO varistor based on Voronoi network. Furthermore, the methods to weaken the current localization and improve the energy absorption capability of ZnO varistor were also analyzed
