Abstract:

Equipment cable maintenance has the need for speed, accuracy, reducing the waste of equipment resources and human resources, so, the failure modes of cables and the current commonly used cable fault detection methods summarize, the cable fault detection methods are mainly divided into traditional fault detection methods and fault detection method based on reflection method, where traditional fault detection methods include bridge method, audio induction method and traveling wave method, and basic methods of fault detection based on reflection include time domain reflection(TDR) method and frequency domain reflection(FDR) method. The principles and the problems of these methods are described, and summarizing the current cable fault detection based on the TDR and FDR combined with other signal processing methods, which facilitate the choice of the method of equipment cable maintenance. Finally, according to the development status of cable fault detection methods, the current problems of cable fault detection technology are summarized, which provides a new direction for future research.
