With the rapid development of power systems and the progress of old city reconstruction projects, power cables are increasingly widely applied to power networks. The basic structure of the power cable comprises a wire core, an insulating layer, a shielding layer and a protective layer. The core, i.e. the conductor, is the part of the power cable that transmits electric energy and is the main structure of the cable. The insulation layer electrically isolates the wire core from the outside. The shielding layer comprises a conductor shielding layer and an insulation shielding layer and is used for preventing radiation interference. The protective layer is used to prevent the penetration of external impurities and moisture and the damage of external force. When partial discharge occurs in the cable, current pulse, electromagnetic radiation, ultrasonic wave, light radiation and the like are generally generated. At present, most power supply units generally take regular inspection for fault monitoring of a cable system, an offline monitoring method is adopted, the monitoring mode is carried out under the condition that equipment is unknown, time and labor are wasted, power failure loss of a user is caused, good equipment can be mistakenly repaired even, and on the other hand, the fault of the cable system between two maintenance periods cannot be timely repaired, so that the maintenance efficiency is low.
