摘要
分析和研究接地阻抗的测试原理,总结了接地阻抗常规测试方法的弊端。从测试电位变化最为缓慢的思路出发,结合对大型地网接地阻抗的实测对比,提出了适用于大型接地网接地阻抗测试的短距离方法。
The defects of traditional measurement are summed up based on the analysis and research on measuring the principle of grounding resistance.According to the slowest change of potential and comparing measurement on large-scale grounding grid,short-distance method is applied to grounding resistance testing for large-scale grounding grid.
