This paper theoretically analyzes the transmission characteristics of induction lightning waves from the overhead distribution lines to the transformer low voltage side. According to the Agrawal transmission line model, the induced voltage of power-line transformer system was analyzed, and the simulation results on the effect of transformer interconnected to the line was obtained. Using transmission line equivalent circuit model and the Thevenin equivalent theorem, supplying lightning induced voltage to distribution transformer, simulating calculation was done.
