Özet: Transformers are among the most important components of the electricity transmission and distribution network. The high efficiency of transformers means that power systems work efficiently. Technological advances in power systems impose responsibility on transformer designers to produce both more economical and more efficient transformers. It is a complex three-dimensional structure consisting of a large number of modules such as transformer, core, windings, isolation, and many other equipments. There are different types of magnetic materials used in the core of the transformer. However, amorphous magnetic materials and transformers designed with these materials have started to be the center of attention. In this study, the Finite Element model of the core-type transformer was analyzed by using FEM-based ANSYS-Maxwell software of the transformer whose core was designed with different magnetic materials to find the losses of the transformer with the same dimensions and operating conditions. Analyzes were made to compare different electromagnetic properties such as magnetic flux density, current density, core losses, eddy current losses, and magnetic vector potential for different core materials.
