Abstract: This Research paper contemplates the leakage flux and stray loss component, especially in the tank walls of the power transformer. For large power transformers, the location and concentration of stray parts had been developed by numerical calculations. A realistic and logical approach has been taken for the reduction of the stray loss in tank walls in Ansys Maxwell 3-D FEM. In this paper different ideologies of the minimization of stay loss of transformer especially in the tank walls have been taken into consideration This reduction technique includes different magnetic materials by considering the economic factors for the optimization of the load loss.
Keywords: Stray loss, tank walls, Shielding, Aluminium.
