5. A double-wound, 1-phase transformer is required to step down from 1900 V to 240 V, 50-Hz. It is to have 1.5 V per turn. Calculate the required number of turns on the primary and secondary windings respectively. The peak value of flux density is required to be not more than 1.2 Wb/m2. Calculate the required cross-sectional area of the steel core. If the output is 10 kVA, calculate the secondary current. [1,267; 160; 56.4 cm2; 41.75 A]
