Long-term practice has shown that partial discharges are the main cause of insulation breakdown in power cables. Since impurities, micro-pores, protrusions of the semiconductive layer and delamination defects, which are liable to occur inside the insulating layer during the manufacturing and jointing operations of the cable, cause partial discharges to occur. The continuous explosive discharge and the high-pressure gas generated by the discharge can crack the insulator to develop electrical dendrites. Partial discharges initially cross only a portion of the insulating layer, but can continually damage the insulating material, ultimately leading to dielectric breakdown. Therefore, the partial discharge amount of the power cable is closely related to the insulation condition of the power cable, and the change of the partial discharge amount indicates that the cable insulation has the defect that the safe operation of the cable is possibly endangered, so that a cable oscillatory wave partial discharge positioning detection system is required to be used for quickly detecting whether the cable has the discharge phenomenon.
