This study presents a detailed analysis of both near and far stray magnetic fields of dry-type distribution transformers. The results of 3-D eddy-currents simulations performed on real-life transformer geometries along with the modeling details are presented. The extensive and rigorous verification of the simulation results was performed by comparison against measurements with the aim of objectively quantifying the achieved simulations accuracy. The obtained results show a high accuracy level of our simulations, allowing for design to be based on simulations with shorter development time and costs compared to the previously predominant prototypes-based design.
