7.1 A'single-phase, 5-kVA, 240:120 V, 60 Hz transformer has leakage imped- ance of 0.18 + j0.230 in the high-voltage wirding and 0.003 + j0.0045 2 in the low voltage winding. The shunt branch accounting for the exciting current has an admittance of (0.648 - j4.48) x 10 mhos when viewed from'the low voltage side. Perform the following: a. Draw the exact equivalent circuit referred to the low-voltage side b. Draw the exact equivalent circuit referred to the high-voltage side 7.1 A'single-phase, 5-kVA, 240:120 V, 60 Hz transformer has leakage imped- ance of 0.18 + j0.230 in the high-voltage wirding and 0.003 + j0.0045 2 in the low voltage winding.
