In the present article, in addition of presenting finite element models, the coupled field-circuit approach is proposed for the modeling of high frequency electromagnetic transients in a multi-winding traction transformer. The proposed method uses two-dimensional finite element models coupled with an external circuit to model the electromagnetic transient behavior of the multi-winding traction transformer. Afterwards, the results of the presented method have been compared with the results obtained from a complete three-dimensional finite element model as well as the detail model's results and the results are validated. Finally, the validated high-frequency model has been used to study the impulse response of the transformer. As shown, the proposed approach is a simple and fast method, and also has good accuracy in modeling of the impulse voltage distribution in the multi-winding traction transformer's windings. }, URL = {http://journals.sut.ac.ir/jnsee/article-1-243-en.html}, eprint = {http://journals.sut.ac.ir/jnsee/article-1-243-en.pdf}, journal = {Nonlinear Systems in Electrical Engineering}, doi = {}, year = {2020} }
