Abstract

Substation grounding device is a hidden project, there is no effective detection means for fault analysis. In this paper, the detection technology of ground penetrating radar is applied to the analysis of abnormal current when the grounding device of EHV substation is connected. Through the positioning analysis of ground penetrating radar, it is determined that the abnormal current is caused by the closed loop formed by the grounding device after being connected and the loop current formed under the action of surrounding electromagnetic environment. Through the detection of ground penetrating radar technology, the problems of abnormal current and spark discharge in the laying and connecting process of dry-type reactor grounding device were successfully solved to ensure the smooth implementation of infrastructure projects.
