22 A single-phase, 2400/240-V, 120-KVA two-winding transformer is connected as an auto-transformer with additive polarity. Determine the kVA rating of the auto- transformer and also the power transformed and the power conducted. Draw the circuit diagram and show the current distribution. If the efficiency of the two-winding transformer is 98 percent on full-load at unity power factor, find the efficiency of the auto-transformer on full-load at unity power factor (15) Total = 40 Marks
