一、问题的提出在研究接地电阻测量方法的一些文献中,通常所讨论的都是一个独立接地网的电阻的测量问题。对于某些更复杂的接地情况,例如两个相距较远的大接地网并联构成的复杂接地系统的电阻测量问题,则很少研究。因此,在测量工作中碰到这类接地系统时,通常仍采用测量一个独立接地网的电阻的方法。 I. PROBLEM PROBLEMS In some of the literature on grounding resistance measurement methods, what is commonly discussed is the measurement of the resistance of an individual ground network. For some more complex grounding conditions, such as two large grounding grids in parallel to form a complex grounding system resistance measurement problems, but little research. Therefore, in the measurement work encountered such a grounding system, the method is usually still used to measure the resistance of a separate ground network.
