Review of Research on Running Condition Monitoring of High Voltage Cables

At present, the reliability of power supply of high-voltage cables is a technical hotspot and difficulty that is closely watched in the world. This paper reviews the running condition monitoring techniques applied to high-voltage cables. First, the principle analysis and characteristic comparison of various PD detection techniques are reviewed; secondly, the overview and principles of five running temperature monitoring techniques are reviewed; in addition, the theory and application of ground current detection techniques are reviewed; finally, the cable condition diagnosis technology is reviewed. To monitor the running condition of high-voltage cables, make reasonable judgments, find defects in time, and then improve the reliability of power supply. This paper provides theoretical and application guidance.
