摘要
介绍了 2 2 0kV氧化锌避雷器现场直流 1mA电压 (U1mA)及 0 .75U1mA下的泄漏电流试验的两种接线方法 ;指出微安表接在高压侧的弊端 。
The leakage current test of 220kV oxide zinc lightning arrester field DC under lmA voltage(UlmA) and 0.75 UlmA and absuse of microampere meter conneted to high voltage side are described. The proposals that microampere meter conneted to low voltage side are put forward.
