Abstract
In order to measure the surface magnetic induction intensity caused by the exciting current of substation grounding grids and testing the fault of grounding grids, the EMI characteristics are obtained by measuring and analyzing the work frequency and transient EMI in substation. Based on electromagnetic induction method, the surface magnetic induction intensity is measured by advanced electronic technology in complicated EMI environment in substation. Experiments and application show that the measuring method is feasible and practical; it can be used in engineering practice of diagnosis the fault of the grounding grids.
