Different transformer models are examined for the calculation of the no-load losses using finite element analysis. Twodimensional and three-dimensional finite element analyses models are used for the simulation of the transformer. Results of the finite element method are also compared with the experimental results. The results show that 3-dimensional model provides high accuracy as compared to the 2-dimensional models. However, the 2-dimensional half model is the less timeconsuming method as compared to the 3 and 2-dimensional full models. Simulation time duration taken by the different models of the transformer is also compared. The difference between the 3-dimensional finite element method and experimental results are less than 3%. These numerical methods can help transformer designers to minimize the development of the prototype transformers.
