摘要
在采用三极法测量大型接地网接地电阻的试验中,电流极和电流极线路的布置方式是整个试验的基础,对测试结果起着决定性作用。对云南某变电站接地电阻进行现场测量试验,结果表明:电流极线路的长度对测试结果有影响,当架空线作为电流极线路时,避雷线有分流作用。
The length of current electrode in the three-electrode grounding resistance depends on the substation grounding, soil textures and the accuracy of measure. When the aerial line is used as the current electrode, the shunt of overhead ground wire will impact the result of measure
