摘要
分析了用补偿法测量两层土壤中接地网接地电阻产生的误差 ,研究了测量误差与土壤反射系数及土壤厚度之间的关系 ,得出了在测量两层不均匀土壤中接地网的接地电阻时准确地插入电压极可提高补偿法测量不均匀土壤接地电阻准确度的结论。
The error produced by measuring the resistance of ground grids buried in two layer soil by compensating method was analyzed. The effect of the thickness of the soil’s first layer and the coefficient of reflection of the soil was studied. The correct locations of the potential pole at different conditions were pointed out. It makes better and wider use of the compensating method to measure the resistance of grounding grids buried in two layer soil.
