The purpose of this study is to verify the theoretical calculations of a three-phase transformer by analyzing its magnetic field behaviors and losses under no-load and full-load working conditions using an advanced simulation program that runs based on finite elements method (FEM). This paper presents detailed explanations on defining the parameters and obtaining the results, and also the calculation method for determining the magnitude of the magnetic field and the core and ohmic losses of the transformer. The reliability of the analysis is confirmed by theoretical calculation results.
