摘　　要：为解决复杂地网的接地电阻值测量不准确的问题,提出了间接测量的方法。首先测得距离复杂地网不太远的简单地网的接地电阻值,然后将复杂地网与该简单地网相连,在连接引线的两端注入电流,进而得到回路总电阻,通过测量简单地网的抬升电位,修正回路电阻进而得到复杂地网接地电阻。通过使用地网分析软件CDEGS进行建模分析,论证了该方法的可行性。This paper proposed an indirect measurement method to solve inaccurate measurement of the resistance value of complex ground grids problem.It measured the resistance value of a simple ground grid not far from the complex ground grid.In addition,it connected the complex ground network to the simple ground grid and injected current at both ends of the connecting lead to obtain the total loop resistance.By measuring the electric potential rise,it revised the circuit resistance and obtained the resistance of the complex ground gird.This research proved the feasibility of this method by using the ground network analysis software CDEGS for modeling and analysis.
