输电线路经高阻短路时助增电流对测距精度的影响不易克服，但当弧光电阻阶段性变化时，从线路一侧测量到的距离和电阻具有线性变化的关系。通过对测量值的线性拟合，能估计出过渡电阻为零时的测量距离。该方法可直接用于微机保护和故障测距装置。

It is difficult to eliminate the effect of fault current fromremote end due to fault path resistance on the accuracy of fault location,but when fault path resistance changes by stages,the distance and the resistance measured at one end have a liner relationship.Through simulating measured values,the measured distance of zero fault resistance can be estimated.The technique can be used in microprocessor protection and fault location devices directly.
