Condition Assessment of Medium-Voltage XLPE-Insulated Cables Degraded by Water Treeing

在澳大利亚，退化的地下XLPE电缆正在造成电力供应中断和高社区成本。目前还没有可靠的无创技术来预测电缆的状况，以优化电缆的更换和翻新。在这个项目中，将对22千伏电缆进行大规模试验，以确定一种新的电缆翻新技术的有效性。利用老化实验的独特数据和基本现象的计算机模型，将开发评估电缆状况的新技术。这个项目的成功结论将为行业合作伙伴和其他配电公司节省数千万美元。

In Australia degraded underground XLPE cables are causing disruption of electricity supplies and high community costs. There is no reliable non-invasive technique for prediction of cable condition to optimise cable replacement and refurbishment. In this project a large-scale experiment will be undertaken on 22 kV cables to ascertain the effectiveness of a new cable refurbishment technology. New techniques for assessment of cable condition will be developed using unique data from the ageing experiment and computer models of fundamental phenomena. Successful conclusions from this project will save the industry partner and other electricity distribution companies tens of millions of dollars.
