英文摘要：

The accurate measurement of grounding grid performance parameters is the main basis to judge the safety of grounding grid. Therefore, it is very important to improve the accuracy of grounding measurement instrument for the safety of the grounding grid. Firstly, the paper proposes the design parameters of calibration system for the grounding measurement instrument. Then the paper designs grounding impedance test system, shunt vector test system and step potential / contact potential value calibration test system. Finally, the paper makes actual measurement and verification of the ZC-8, the grounding characteris-fics of large grounding grid and the shunt vector measuring device. The results verify the validity of the system for the grounding measurement instrument, which can test the performance of the grounding measuring instruments on the market and determine the performance parameters of the instruments to make sure the accuracy and validity of the grounding grids performance measurement.
