Impacts of amorphous metal-based transformers on energy efficiency and environment

Abstract: Magnetic properties of a recently developed Fe-based amorphous alloy with a high saturation induction of 1.65T are reviewed. The increased saturation induction is fully utilized in transformers with reduced magnetic losses, physical sizes and audible noises, minimizing some of the drawbacks of amorphous metal-based transformers based on a currently available amorphous alloy. Impacts of this on the worldwide energy savings and reduction of greenhouse gas emissions are discussed. A recent effort in achieving a saturation induction beyond 1.65T in nanocrystalline alloys is mentioned. [Copyright &y& Elsevier]
