摘要
对敷设后的交联聚乙烯电缆进行局部放电检测比较困难。针对这一问题 ,本文介绍了差分法和电磁耦合法。这两种方法具有方便灵活、操作安全、抗干扰性强等优点 ,适合于现场验收试验和在线检测。
It is comparatively difficult to carry out partial discharge detection as an after laying test for XLPE cable lines. Aiming at such problem, this paper introduces two methods of on site PD measurements, i.e. the differential method and the electromagnetic coupling method. These two methods can be used easily, safely with good immunity to electromagnetic interference, therefore, they are suitable for on site testing and on line monitoring.
