摘要（英）：

The invention discloses a grounding device impacted grounding resistance measuring method and a system. In comparison to the prior art, the measuring method utilizes the master frequencies of current sampling signals and voltage sampling signals to calculate the grounding resistance impacted by a to-be-detected grounding device. The model for such a method can be easily built and conveniently calculated for high accuracy. Further, the invention also discloses a measuring system for the grounding device impacted grounding resistance by providing a plurality of voltage output gears such as 500V, 750V, etc. and outputting multi-waveform inrush current such as 30/80us, 10/350us, etc. Small in size, convenient to move, and high in safety, the method and the system can be applied to test grounding device impacted grounding resistance in the wild field.
