摘要
分析了高电压直流耐压试验可有效发现纸绝缘电缆缺陷,但在发现交联聚乙烯绝缘电力电缆缺陷方面有局限性。介绍了通过分析直流耐压试验、泄漏电流来判断电力电缆主绝缘缺陷的方法。
The HVDC withstand voltage test can discover the defect of paper insulated cable efficiently, but it has limitation ha discovering the defect of cross - linked polyethylene insulated power cable. The method to judge defect of main insulation for power cable through analysis of DC withstand voltage test and leakage current was introduced.
