The resistances and leakage reactances in ohms of a 25-kVA, 60-Hz, 2400:240-V distribution transformer are
R1 = 0.650 Ω
R2 = 0.00650 Ω
Xl1 = 8.40
Xl2 = 0.0840 Ω

where subscript 1 denotes the 2400-V winding and subscript 2 denotes the 240-V winding.

Each quantity is referred to its own side of the transformer.

(a) Draw the equivalent circuit referred to (i) the high- and (ii) the low-voltage sides. Label the impedances numerically.

(b) Consider the transformer to deliver its rated kilovoltamperes at 0.80 power factor lagging to a load on the low-voltage side with 240 V across the load. Find the highside terminal voltage.
