A 125 KVA transformer has 250 turns on the primary and 50 turns on the secondary. The primary and secondary resistances are 0.4 Ω and 0.15 Ω respectively and the corresponding reactances are 1.5 Ω and 0.07 Ω respectively. The supply voltage is 2600 V. Calculate the secondary terminal voltage for a full load having p.f of 0.8 leading. Solve it by using an equivalent circuit referred to as the primary side.
