摘要

750 kV substation of Riyue Mountain,Qinghai is a substation that annual average thunderstorm days are the maximum at the same voltage level and altitude in the world.We detailedly described testing methods and steps of 6 characteristic parameters for grounding device of 750 kV substation by using 8000S comprehensive test system,and scientifically judged overall performance of the grounding device.Moreover,we especially emphasized key and difficult points in testing process,providing reference for the majority of grounding test workers.
