Fast Hybrid Approach for Calculation of Losses in Outer Packages of Transformer Core due to Perpendicular Stray Flux

Stray flux in transformer is causing local losses and overheating in outer packages of a transformer core. Proper modelling of those losses is important during power transformer design process. Using 3D FEM for this problem is impractical, so another approach should be used. Therefore, in the paper the hybrid approach using various 2D models is proposed.
