摘　　要：为了更有效地对接地网进行测量,引入了一种新方法。方法原理运用冲击电流注入电网作为测量电流,采用电位降法进行实际测量,能准确地测量冲击接地电阻和冲击电位分布,可有效地实现对大型接地网的测量。通过对电厂的现场实测,并对所得数据分析,证明该方法具有实际工程意义。In this paper to measure effectively rounding grid, introduced a new method. The principle is putting the impulse current into the earth and using it as the measurement current, measuring accurately the impulse grounding resistance and the impulse potential distribution and measuring effectively the large grounding grids. Through measuring power plant and researching analysis of data,proves that this method can be put into the project.
