description: The subject of graduate qualification work Â«Designing of three-phase power oil transformer ONAF-25000/35Â». This project is dedicated to design three-phase power oil transformer ONAF-25000/35, rated power 25000 kVÂ·A, voltage class 35 kV, rated voltage 38/10 kV with natural oil cooling and forced air cooling, on-load tap changer, with windings of dif-ferent materials: copper and aluminum. During the completion of project there was studied design criteria, preliminary computer calculation, studied some methods of loss reduction, calculation of windings, magnetic system, transformer losses and its effi-ciency, thermal, mechanical, economic calculations and a summary table of calcula-tions with comments. As a result, the best option was chosen.
