In order to discuss the arc resistance of synthetic resin, it is quite important to know the relation between arc resistance time and applied voltage. In this study, an attempt was made to derive the arc resistance time-applied voltage curve under the consideration that the arc deterioration of insulating materials is completed when the sum of deterioration caused by each discharge becomes above a limiting value. Several assumptions were used in the present step, but it is considered that those assumptions must be improved and be proven by the experimental and theoretical studies in future.
Furthermore, the progress of deterioration was defined here and the tendency of its variation with the elapsed time was clarified.
