| Abstract: | This article briefly introduces the pulse reflection method to test the cable fault waveform and distance measurement,including the low resistance, high resistance, wire break, leak and flashover of cable fault. Of fault point at both ends or near ends （ blind area） of the cable, the waveform distortion are theoretically studied and experi- mentally discussed. And then find out the theory basis of waveform distortion and the effective method to measurement fault in the special condition. |
