A 199 KVA transformer has 489 turns on the primary and 149 turns on the secondary. The primary and secondary resistances are 0 30 and 0.01 0, respectively and the corresponding leakage reactances are 1.1 0 and 0.035 0, respectively. The rated supply voltage is 2407 V. Calculate the increase in the secondary voltage when the transformer is operated on full-load at a p.f. of 0.8 leading. Round your answer off to 2 decimai places
