Finite Element Method (FEM) based Design and Simulation of Practical Transformer with Nano-Crystalline Core Using ANSYS

Abstract

Transformer is the main apparatus of the power system for both transmission and distribution of electrical energy. It is the important component of electrical engineering because of its high efficiency and helps in step up and step down the voltage, impedance matching and circuit isolation. Team of designers, engineers and building owners struggled for high-performance in order to maximize the transformer efficiencies. Design and selection of material to construct a transformer core is a significant process. The purpose of this study is to model and simulate a practical 12.5MVA, 66/11kV, three phase power transformer with Nano-crystalline materials like FINEMET and VITROPERM using ANSYS. The study also put some light on the usage of these materials for core as they shows reduced losses in transformer.
