| Abstract: | Based on the example of overproof on-load loss in 180MVA/220kV power transformer, the eddy loss in windings is analyzed with the leakage flux finite element software. The influence of transformer radial leakage flux to the eddy loss in windings is discussed. A method to arrange axial magnetic potential of large transformer is presented. |
