Abstract :
A new type of 110 kV and 220 kV whole-solid-insulation polymeric ZnO surge arresters are developed. The power loss characteristics of ZnO varistors are discussed, which are simulated by an artificial neural network (ANN) model. The thermal performances of the new developed polymeric arresters are analyzed by the finite element method (FEM). The thermal dispersion capability and thermal stability of the developed whole-solid-insulation polymeric ZnO surge arresters are presented.
