摘　　要：根据电缆故障点电弧呈纯电阻性特性提出了一种在线故障测距方程,并进行了数字仿真和实验。结果表明该方法可改变现有的电缆离线测距方式且具有较高的精度。The present methods of power cable fault distance locating are all based on traveling wave method and are off-line detection. This paper gives an on-line fault distance locating method which is based on purely resistance characteristic of fault point. The mathematical simulation and test are made. The results show that this method has higher accuracy and is practical for on-line distance locating.
