The Namgang hydroelectric power plant which is 7㎿×2 a cross axile bulb type generates 42 GWh per year. While checking the Namgang hydroelectric power plant outside substation main transformer as thermal image camera, there was heating phenomenon in side of generator bus bar flange. In this paper, electromagnetic analysis based on Maxwell equation investigates the cause of Namgang hydroelectric power plant outside substation main transformer bus bar flange heating phenomenon as eddy current and Maxwell program simulation come up with and ideal material flange that compared to three types material different relative permeability and conductivity.
