摘　　要：结合某位于山顶的工程,阐述了大型接地网接地电阻的测量方法,并指出了辐射型接地极的作用,且终端接地极对接地电阻值无阻值要求,为类似工程电气设计提供了参考。Combined with the project at a mountaintop, the ground resistance measurement of grounding net and the effect of radial pattern earth electrode were described. It was pointed out that the ground resistance of earth electrode has no requirment of resistance range. It could provide references for similar engineering.
