Abstract	The solid-layer method (SLM) and the icing-water- conductivity method (IWCM) are widely used in the insulator icing tests, but little research has been dedicated to the equivalence of these two methods. Based on the research on dc flashover performance of ice-covered insulators in the artificial climate chamber, this paper studied the equivalent relation between SLM and IWCM according to the equivalent principle of the flashover stress of ice-covered insulators. The results show that the influence of these two methods on flashover stress of iced insulator is equivalent, and this equivalence is determined by the configuration of insulator as well as the icing degree, but the icing flashover stress of the same type of insulators which are on the same pollution level simulated by the two different methods is consistent.
