要約(日本語): In this research, the electromagnetic code FEKO is selected to realize the model creation and lightning surge analysis, which is a simulation tool using MoM and well fit for surge characteristic analysis. It also has a built-in Fourier-Transform for time-domain analysis and optmizer for model parameters optimization [1]. A transformer model for lightning surge analysis using is represented. An equivalent massive core model is created from the information of the 27ZH100 CRGO (Cold Rolled Grain Oriented) steel core with 200 laminations and 48×10-6 Ωcm resistivity. The winding is assumed as perfect conductive thin wires. And it takes into account of the skin effect of the winding. Step response analysis of a simulated lightning source is carried out.
