Insulation Fault Detection and Optimization System of High Voltage XLPE Cable Sheath

In order to monitor the insulation fault of high voltage XLPE cable sheath and optimize it scientifically, a novel XLPE cable sheath insulation fault detection and optimization system based on difference frequency method is designed in this paper. The system mainly monitors and analyzes the insulation aging caused by water branches in XLPE power cables, and obtains the final detection results through simulation experiments. The results demonstrate that the system can accurately and continuously monitor the insulation fault of high voltage XLPE cable sheath, and scientifically optimize it, so as to make XLPE power cable provide the basis and premise for the safety and stability of power system.
