Abstract

Accurate simulation and loss estimation in power transformers are crucial for both the design phase and useful life of the transformer. In this study, core losses and magnetic flux densities of a power transformer for different frequency values are calculated. For this, ANSYS @ MAXWELL software based on the Finite Elements Method (SEY) and the 3D simulation model of the transformer were examined. The results obtained from simulations performed at 50 Hz and 60 Hz frequencies were compared with theoretical and experimental results. It has been observed that increasing the frequency causes increased heat and loss in the core of the transformer.

Keywords
