浅谈屏蔽电力电缆的超低频测试方法

Discussion on the Shield Power Cable’s Ultra Low Frequency Test Method

针对传统的直流测试方法在寻找交联聚乙烯绝缘电缆隐患方面存在的不足,介绍了超低频测试方法的应用基础和优势,即可以主动查找到电缆网络中的一些潜在故障,并对其应用进行了分析。

In the light of the shortages of the traditional DC test method in identifying the potential dangers in power cable with cross-linked polyethylene insulation,introduces the application base and superiority of the ultra low frequency test method,that is to be able to find some latent faults in the cable system actively,and analyzes its application.
