A step down transformer can decrease the voltage level and increase the current level by keeping constant power and frequency which gives needful output to a substation. To get this require output transformer design should be splendid. This paper based on transformer design and analysis which can reduce copper and core losses with proficient cost. Step lop core lamination reduce no load voltage up to 8% no load current up to 50% with low noise level. Payback analysis will give the comparison between proposed designed transformer and normal designed transformer.
