Example 33.5. A 3-phase transformer, ratio 33/6.6-kV, A/Y, 2-MVA has a primary resistance of 8 per phase and a secondary resistance of 0.08 ohm per phase. The percentage impedance is 7%. Calculate the secondary voltage with rated primary voltage and hence the regulation for full-load 0.75 p.f. lagging conditions. (Elect. Machine-I, Nagpur, Univ. 1993)
