Transient mechanical force in transformer induced critical mechanical stress on windings and transformers in radial and axial directions. In this paper, impact of force’s within transient inrush current duration on MV three phase transformer with propose novelty winding configuration (S-P-S) to considered. In order to forces analysis, a 3-D model of three phase transformer developed by use Ansoft Maxwell V15.0. Magnetic vector potential, Magnetic flux density and electro-mechanical force’s of SPS-type and conventional-type of configuration windings and transformer calculated from a 3D finite element model. Based on the comparison and result analysis, proposed an optimal configuration for transformer winding in order to trade-off and minimization of electromechanical force’s in the transient inrush current state.
