A 3-phase, 50 Hz transformer has an iron cross section of 200 cm2. If the flux density be limited to 1.5 wb/m2. The voltage ratio is 4400/220 V, the high voltage side being connected in star and low voltage in delta. Stacking factor is 0.8. The sum of number of turns per phase on high and low voltage winding is
