The development trends in amorphous core transformer

The need for more efficient transformer core materials, due to increased recognition by the loss reduction of electric utilities, has spurred the development of amorphous metal usage in transformer. The loss of amorphous core is one third to one fourth that of silicon steel at equivalent inductions 15KG and below. Thus, the substitution of amorphous metal for conventional silicon steel in a transformer core can reduce core loss by 75%. This paper describes the development trend, the manufacturing processes of amorphous core transformer and the characteristics of amorphous core transformer in comparison with those of silicon core transformer.
