On-line Fault Distance-locating Method for Power Cable Based on Arc Characteristics

Zhang Qunfeng et al  
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.
