A single-phase 240/120 V transformer has the following parameters:
R1 = 1-ohm; R2= 0.5 -ohm; X1 =6 -ohm; X2 = 2 -ohm; R0 = 500 -ohm; X0 = 1.5k -ohm.
A load of 10 -ohm at 0.8 power factor lagging is connected across the low-voltage terminals of the transformer. The voltage measured across the load side is 110V. Compute the following:
(a) Load voltage referred to the primary side
(b) Currents of the primary and secondary windings
(c) Source voltage
(d) Voltage regulation
(e) Load power
(f) Efficiency of the transformer
