Abstract
Transformer efficiency is significantly affected by losses occurring within its core and windings, with core losses constituting a major portion of the total losses. This study investigates the reduction of transformer core losses through the optimization of core materials. Various magnetic core materials, such as grain-oriented electrical steel (GOES), amorphous steel, and nanocrystalline alloys, were evaluated for their loss characteristics under different operating conditions. Statistical analysis was employed to quantify the influence of material properties on core loss minimization. The experimental methodology involved building model transformers using different core materials, and measuring their no-load losses, load losses, and efficiency. Results indicate that the use of amorphous and nanocrystalline materials considerably reduces core losses compared to traditional GOES cores. The study concludes that careful selection and optimization of transformer core materials can lead to significant improvements in transformer performance, reliability, and energy efficiency.
