Research on Key Technology of Fault Diagnosis of Power Cables

摘要

With the expansion of city scale and the acceleration of the process of urban construction, the power cables plays more and more important role in the city network. At the same time, the increase of the number of cables and the continuous extension of the cable running time result in more and more frequent cable failures. This paper analyzes the common causes of the cable fault, and gives the key technology of the cable fault diagnosis to provide some references for the relative researchers.
