| 摘 要： | 提出了测量大型地网接地电阻的一种新方法──电位极移动的双电位线法。克服了接地电阻测量中的非正交感应电势的影响，方便、有效地解决了仅用一回架空线路测量大型地网接地电阻的问题。这一新方法在紧水滩电厂地网接地电阻的测量实践中得到了成功的应用。

| Abstract: | This paper presents a new method of ground resistance measurement-two potential leads method with shifting potential electrode. By means of this new method, the nonorthogonally induced voltage risen in the ground resistance measurement can be overcomed practically and the problem of using one circuit overhead line for the ground resistance measurement of large grounding grid is solved. This new method has been applied successfully to the ground resistance measurement of Jinshultan Hydroelectric power Station. |
