2.29 Three 10, 100 kVA, 2300/460 V, 60 Hz transformers are connected to form a 30, 2300/460 V trans- former bank. The equivalent impedance of each transformer referred to its low-voltage side is 0.045 +10.16 2. The transformer is connected to a 36 source through 30 feeders, the impedance of each feeder being 0.5 +j1.5 2. The transformer delivers full load at 460 V and 0.85 power factor lagging. (a) Draw a schematic diagram showing the transformer connection. (b) Determine the single-phase equivalent circuit. (c) Determine the sending end voltage of the 30 source. (d) Determine the transformer winding currents.
