The actual measurement wave is different from academic wave of power cable fault, it need professional test personnels to locate the exact fault position. In order to solve this problem, the HHT( Hilbert-Huang Transform) is adopted to analyze the measurement wave of power cable fault, and the wave been similar to academic wave is obtained. It can achieve accurate measurement result in practice, and provide an effective method for location of power cable fault.%电力电缆故障的实际测试波形与理论波形相差较大,需要经验比较丰富的专业测试人员才能够比较准确地确定出故障位置.针对这一问题,对电力电缆实际故障测试波形采用HHT变换,从而获得与理论波形更为相似的波形.经实际测试,能够获得更为准确的测试结果,为电力电缆故障定位提供了一种更为有效的方法.
