Abstract :
ANEW silicon steel having a magnetic saturation value approximately one third greater than conventional silicon steel has been announced by the Westinghouse Electric and Manufacturing Company. The new material, which has been named Hipersil (high-permeability silicon steel) reaches this higher saturation at the same magnetizing force as conventional silicon steel; its other characteristics are such that the core losses in transformers in which it is being used are no greater at the increased flux densities than they are in transformers using conventional steels
