Gaoya dianqi, 1996 避雷器瓷套表面出现的泄漏电流,将使得从底部入地线中检测得到的阻性电流增加;如果避雷器由多节组成,表面泄漏电流会流入避雷器,造成它的电位分布发生变化,使一部分阀片承受的电压增加,会导致避雷器的老化加快。

Dianci bileiqi, 1992 对于金属氧化物避雷器运行情况的监视主要靠测量泄漏电流.常用的方法有测量全电流、直流测量阻性电流及泄漏电流的谐波分析.本文提出对泄漏电流进行谐波分析的新方法,采用外偿法把系统电压的谐波产生的三次谐波电流消除,以得到仅由避雷器产生的三次电流谐波.然后再确定阻性电流的三次谐波与总的阻性电流的关系.采用电场测量法间接求得容性三次谐波电流.电位及电流信号输入微处理机处理和显示各种参数,与直流测量法相比,其误差在20～25%之间.
