Abstract
This paper presents the results of a test program on the effects of tests used in condition assessment of XLPE cables nearing the end of their life. The test program was carried out on submarine cables removed from service. The work consisted of two parts: Part 1 (cable evaluation tests to determine the condition of the cable) which included partial discharge, 60 Hz tan δ, AC breakdown tests, dissection and water tree analysis, and failure analysis of the failure site, and Part 2 (Effects of testing) which included lab tests to determine the effects of switching surges, VLF tan δ, and the LIpA test. Partial discharge tests were carried out on samples before and after switching surge tests, VLF tan δ tests, and the LIpA Test (Part 2). In addition some of the samples that were subjected to the different tests were aged at 14.4 kV in salt water for 284.5 days. The test results are discussed in term of the effects of the different test techniques used in condition assessment of XLPE cables suffering from advanced water tree related degradation.
本文介绍了一个测试程序的结果,该测试程序用于XLPE电缆接近使用寿命的状态评估。测试项目是在停用的海底电缆上进行的。这项工作包括两部分:第一部分(电缆评估测试,以确定电缆的状况),包括局部放电、60 Hz tan δ、交流击穿测试、解剖和水树分析,以及故障现场的故障分析;第二部分(测试的影响),包括实验室测试,以确定开关浪涌、VLF tan δ和LIpA测试的影响。在开关浪涌试验、VLF tan δ试验和LIpA试验(第二部分)前后分别进行了局部放电试验,并在14.4 kV盐水中进行了284.5 d的老化试验。讨论了不同测试技术对交联聚乙烯电缆受水树相关退化影响的影响。
