| Abstract: | A tentative idea of usingthe variation of interim resistance to achieve the metering ofadapting oneself toimpedance is put forward,the relevant bases of a differentiation are derived,and itspreliminary analysis has been carried out as well.It aims at eliminating the influence ofinterim resistance on metering of impedance protector by changeable property of arcresistance. |
