摘要：

The electromagnetic forces acting upon the transformer windings are calculated by numerical analysis in this paper. The electromagnetic forces consisting of radial and axial directions induce the injurious mechanical stress to windings as well as transformer itself. 3-Dimensional power transformer model by finite element analysis is considered to calculate the electromagnetic forces. The magnetic vector potential, magnetic flux density and electromagnetic forces of the power transformer are calculated numerically, and the results are compared with the analytical results.
