4. The resistances and leakage reactances of a 30-kVA, 60-Hz, 2400-V:240-V distribution transformer is: R₁ = 0.68 2, R2 = 0.0068 2, X₁1 = 7.8 2, X12 = 0.0780 2 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 kVA to a load on the low-voltage side with 230 V across the load. (i) Find the high-side terminal voltage for a load power factor of 0.85 lagging. (ii) Find the high-side terminal voltage for a load power factor of 0.85 leading.
