The mathematical background of this equivalent scheme is described. The determination of the different scheme elements is made through a finite-elements calculation of both main and leakage inductances, for the case of a four-winding transformer. A procedure is defined, which allows to estimate the values of these elements from some measurements on the transformer at no-load and short-circuit operations. A specific strategy of short-circuit tests is described, allowing to determine all parameters in a rather simple way.}, type={Artykuły / Articles}, title={On parameters determination of multi-port equivalent scheme for multi-winding traction transformers}, URL={http://www.journals.pan.pl/Content/85032/PDF/02_paper.pdf}, doi={10.1515/aee-2015-0003}, keywords={multi-winding transformer, equivalent scheme, multi-port circuit, traction transformers}, }
