摘要
从电力电缆故障现状出发,对当前常见的电缆故障定位方法原理以及优缺点进行了剖析,主要包括阻抗法、行波法、声测法、声磁同步法等,最后对电缆故障定位方法的发展趋势进行了展望。
Based on the present situation of power cable fault, the principle, advantages and disadvantages of common cable fault location methods are analyzed, including impedance method, traveling wave method, acoustic measurement method, acoustic magnetic synchronization method and so on. Finally, the development trend of cable fault location method is prospected.
