Abstract

This paper presents high permeability ferromagnetic-cored distribution transformer with capacity of 1MVA, including amorphous HB1, SA1 core and silicon steel core. This paper also outlines experimental results effects of the magnetic properties of magnetostriction on ferromagnetic cores in order to compare with the simulated model for each magnetic core by FEA results, is analyzed. An approach is proposed for obtaining a definite, quantified relationship between the defined magnetostrictive characteristics of the core with different ferromagnetic materials to achieve a lower magnetic core loss, noise level and SCC characteristics are analyzed.
