Abstract

Foundation of water and electric field are essential and assistance requirements to initiation, growth and propagation of the water treeing. So that, this paper presents a new theoretical model of water treeing mechanism in solid insulation. Also, the aim of this paper is studying the effects of configuration parameters of our suggested model on the electric field strength inside microvoid and the interfacial energy between water and insulation material at high frequency for various dielectric insulation kinds (unique, binary-, and multimixture).
