Abstract

The mean ion mobilities in SF6 gas、SF6/air and SF6/R12 gas mix-tures are obtained from the current-voltage measurements under discharge condi-tions. The results indicate that the effectiveness of additives in improving insulation strength of SF6 gas is not ascribed to the change in ion mobilities.
