| Abstract: | In this paper, a novel method is proposed to measure the grounding resistance with short leads, and the measurement system based on this method is developed. The measurement system takes the actual structure of the soil into account, and shortens the length of the leads. The non-power frequency method is introduced into the measurement system, small current is needed in the measurement process. Thus the measurement system is portable, and the measurement process is quite safe. The measurement system has been verified by test. |
