Abstract

Based on the simulation calculation of grounding grid corrosion, a non-excavation method of grounding grid corrosion detection scheme is designed. Firstly, a given excitation current signal is injected into the diagonal of the measurement area of the ground network. Then, the magnetic field intensity of the current conductor directly above the ground is detected, the current intensity is solved by the Bio-Savart law, and R=U/I is calculated with the voltage signal measured between the accessible nodes. Finally, the degree of resistance corrosion between each group of nodes is obtained.
