Distribution transformers with OVAL windings introduces as optimal Optimums transformers in the lowest power. Because consumption of Iron and copper decrease in these transformers, it decreases Loss of power transformers than cylindertransformers. Pay attention to the level of deformation transformers in OVAL, its electromagnetic forces will be reduced. All Articles have given different methods of calculation for electromagnetic forces of cylinder transformers. But, now, electromagnetic forces of OVAL transformers have never decreased. Therefore, this article has considered Transformer Forces Analysis 200kVA. Moreover, it compares this kind of transformer with cylinder transformers 200kVA. These forces are analyzed in two states: normal and Three-phase short circuit. So we can use FINIT ELEMENT METHOD (FEM) in 3D environment. In this method,electromagnetic vector potential,flux density and electromagnetic forces will be calculated.  In this method, software MAXWELL V.13 has been used.
