Abstract
Cilj završnog rada je izrada trofaznog transformatora sa povećanim rasipnim tokovima. Modeliranjem trofaznog transformatora sa rasipnim tokovima postignuti su i određeni gubici transformatora odnosno povećan je rasipni magnetski tok. Prije samog modeliranja napravljena su određena mjerenja i proračuni transformatora te je snimljena petlja histereze. Nakon toga je transformator rastavljen i ponovno sastavljen ali sa zračnim rasporom između stupa jezgre i primarnog namota. To je ostvareno pomoću plastičnih uložaka koji su printani 3D printerom. Izvršena su nova mjerenja te je snimljena petlja histereze kao i struja magnetiziranja. U programskom paketu FEMM (Finite Element Method Magnetics) napravljene su određene simulacije koje ukazuju kako se rasipni magnetski tok mijenja s promjenom konstrukcije željezne jezgre.

The aim of the dissertation is the development of a three-phase transformer with increased leakage flux. Modeling the three-phase transformer with leakage fluxes resulted in certain losses in transformer and increased magnetic leakage flux. Before the modeling, the measurements and calculations of the transformer were made and the hysteresis loop was recorded. After that, the transformer was disassembled and re- assembled, but this time with an air gap between the core and the primary winding. This is achieved by using plastic cartridges that were made by a 3D printer. After this, new measurements were taken, the hysteresis loop was recorded and current magnetization was measured. Simulations that show how magnetic leakage flux changes when the structure of the iron core is altered were made in the program package FEMM (Finite Element Method Magnetics).
