摘要：
This paper describes the development of a theoretical model to predict flashover voltage of nonceramic insulators. The model is based on reignition and arc constants that have been derived from electric field simulations and experimental data of flashover voltage and surface resistance measurements. New and field-aged silicone rubber and ethylene propylene diene monomer rubber samples were evaluated. A good correlation of the calculations from the model with experimental data has been demonstrated.
