| 摘 要： | 运行中的氧化锌避雷器要定期进行电气性能测试。介绍了直流1mA动作电压U1mA和0．75U1mA电压下的泄漏电流参数测试的拆高压引线与不拆高压引线两种测试方法、接线，以及实测结果的比较。分析和实测都表明，不拆高压引线测试方法可行，效果良好。

| Abstract: | Zinc oxide arrester in operation stage needs electrical test periodically. The paper introduces two methods of measuring operating voltage U1mA and leakage current at voltage of 0.75 U1mA with or without HV lead of arrester dismantled, corresponding connections and the comparison of measured results. Both analysis and practical measurement show that the method without HV lead dismantled is flexible and well effective. |
