Abstract

Cold rolled grain oriented (CRGO) electrical steel is a critical raw material for manufacturing of transformers, which is fully imported as it is not manufactured in India. Currently India consumes about 2.5 lakh metric tonne per annum of CRGO electrical steel and with the growth in demand of transformation capacity the consumption is estimated to be 11.5 lakh metric tonne and 13.5 lakh metric tonne respectively during the 12th and 13th five-year plan period. Magnetic cores for the wide range of modern electrical and electronic devices require magnetic materials with many combinations of properties and characteristics. The evaluation of magnetic core materials is very crucial before using for transformers, motors and Inductors.
