Abstract
Recently, electric power equipments insulated by epoxy resins have been accident-filled, so that we have been interested in the degradation character of epoxy resin insulations at normal temperature to estimate their life. Thus the aging tests on epoxy insulations were accomplished, and then resistive leakage current on their insulations kept in a glass state at 90 and 80°C was measured by the method canceling capacitive current which was applied to degradation estimation of ZnO varistors. Results of reduced resistive leakage current were led to evaporation and migration of hydrogen ions in epoxy insulations, which are compared between new ones and used ones and applied to estimation of aging degradation in this paper.
