摘要

电力电缆是配电系统中具有将电能从电源输送到负载的功能的设备。电力电缆剩余寿命的估算对保证配电系统的可靠性具有重要意义。局部放电测量作为高压设备诊断的最佳方法，可为电力电缆剩余寿命的估计提供参考。本文讨论了采用不同电压等级对海底电力电缆XLPE绝缘进行局部放电测试的结果，并利用该结果估算了电力电缆在载荷因素下的剩余寿命。试验结果表明，电压水平与局部放电充电值之间存在显著的关系。

Methods for Remaining Life Prediction of Power Cable based on Partial Discharge with Regard to Loading Factor Calculation and Voltage Variation

Power cable is equipment in an electrical distribution system that has functions to deliver electrical energy from the source to the load. Estimates of power cable remaining life are important to be done for ensure the reliability of the electricity distribution system. Partial discharge measurement as a best method of high voltage equipment diagnosis can be a reference in estimating the remaining life of power cables. This paper discusses the results of partial discharge testing on XLPE insulation of subsea power cables using several voltage levels and use that result to estimates the remaining life of the power cable with regard to loading factor. based on the test, there is a significant relationship between voltage level and the charge value of partial discharge.
