A single-phase 120 kVA, 2400/240 V, 60-Hz distribution transformer is used as a step-down trans- former. The load, which is connected to the 240-V secondary winding, absorbs 110 kVA at 0.85 power factor lagging and is at 230 V. Winding resistances are R-2 52 and R -0.05 52; leakage reactances are X = 2.5 2 and X-0.02 2. Calculate the following (using actual values): a) equivalent series impedance, referred to the primary b) primary voltage c) the real and reactive power supplied to the primary winding Using transformer ratings as base values, rework Problem in per-unit.
