摘要：By studying the depth and length of groove defect, this paper explores its effect on the propagation of SH0 wave in the flat steel of substation grounding network. The results show that the sensitivity of SH0 wave to defect detection in the propagation process depends on the depth of defect, that is, the corrosion cross-sectional area. Reflection waves are difficult to detect when the defect cross-sectional area is less than 18.75%. The smaller the defect depth, the weaker the echo signal.
