Description
Summary:In this paper, the research progress of soil discharge phenomenon is comprehensively analyzed from three aspects: soil discharge imaging technology, soil impact breakdown mechanism and calculation method of grounding device impact characteristics. It is urgent to collect the important image data of soil discharge in order to study the regional structure model of soil discharge, and then accurately calculate the electrical parameters of soil discharge characteristics, and apply it to the calculation of transient model. Compared with the numerical calculation methods of grounding device, the electromagnetic field method is recommended for the calculation of impact characteristics.
