摘要
分析了理想接地球体状况下,垂直地面方向两层分层和水平方向两层分层的土壤结构对现行规程推荐的0 618法和30°夹角法测量地网接地电阻误差的影响,并对测量引线间互感对测试结果的影响进行了计算分析。
This paper analyzes the error of grounding resistance measurement (using linear approach and 30°angular approach recommend by corresponding standard) of ideal grounding globe in vertically and horizontally layered soil structure. The influence of the mutual inductance between current probe lead and voltage probe lead is also analyzed.
