Abstract	It is well known that accurate measurement of grounding resistance and inductance under impulse voltage is of great importance for safe operation of electrical and electronic equipment. It is the behavior of grounding objects under impulse voltage instead under DC voltage that determine the safe operation of equipment. However, the existing method and equipment cannot meet the requirement. A new method to realize accurate measurement of grounding impedance and a device, which can produce adjustable wave form of impulse voltage with enough power, can automatically measure and calculate the grounding resistance and inductance, is presented in the paper. The measurement principles, hardware structure and numerical method are described, then the results of experimental results and field measurement results are presented. From these results, we can see that the principle proposed in the paper is correct, the device can meet the requirement of practical measurement, can be used in practical measurement of grounding parameters, which is useful for safe operation of equipment and for economical construction of grounding net.
