双层土壤中环形及星形电极接地电阻的解析

The Grounding Resistance of Ring Type and Star Type of Electrodes in Double Layers Soil

基于双层土壤中任意形状接地网的接地电阻公式 ,导出了双层土壤中正方环、圆环及星形射线电极的接地电阻解析公式。验证计算结果表明

Based on the formula of calculation of grounding resistance of grounding grid in two layers soil the calculation formula of grounding resistance of square, ring and star type of electrodes in two layers is derived. The results show it agrees with the results of numerical arithmetic.
