Rg = resistance of grid conductors 意思是 Rg = 网格导体电阻 ρ = Soil resistivity encountered by grid conductors buried at depth h in ohm 意思是 ρ = 网格所在的深度为h的土壤电阻(以欧姆为单位) A = Area covered by grid of dimension in square meters 意思是 A = 网格覆盖范围的面积(平方米) LT = Total length of grid conductors in meters 意思是 LT = 网格的总长度(米) h = Depth of grid burial in meters 意思是 h = 网格掩埋的深度(米) 也就是说,这个公式是求地网的阻值的,当然,知道其中的任意4项,也可求出第5项来。
