摘要
提出了利用过渡电阻增量实现阻抗自适应测量的设想，导出了其动作判据，并对该判据进行了初步分析，旨在利用故障点电弧电阻的变化特性来消除过渡电阻对距离保护正确测量的影响。
A tentative idea of using the variation of interim resistance to achieve the metering of adapting oneself to impedance is put forward,the relevant bases of a differentiation are derived,and its preliminary analysis has been carried out as well.It aims at eliminating the influence of interim resistance on metering of impedance protector by changeable property of arc resistance.
