cable fault test waveform reconstruction fault position location time-domain pulse reflection
In order to improve the accuracy of cable fault position location at a low cost and make the testing results intuitive, a cable fault detector based on waveform reconstruction is designed. In this detector, the cable fault position is located based on the time-domain pulse reflection(TDR)principle. A pulse waveform is injected in the tested cable, and a high-speed comparator with changeable reference voltages is used to binarize the test pulse waveform to a binary sequence on a certain voltage. Through scanning the reference voltage in a full voltage range, multi-sequences are acquired to reconstruct the pulse waveform transmission in the cable, and then the pulse attenuation feature, electrical open circuit fault, electrical short circuit fault, and the fault position of the cable are diagnosed. Experimental results show that the designed cable fault detector can determine the fault type and its position of the cable being tested, and the testing results are intuitive.
