Three lo, 100 kVA, 2300/460 V, 60 Hz transformers are connected to form a 36, 2300/460 V trans- former bank. The equivalent impedance of each transformer referred to its low-voltage side is 0.045 + j0.16 N. The transformer is connected to a 30 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 3p source. (d) Determine the transformer winding currents. Three lo, 100 kVA, 2300/460 V, 60 Hz transformers are connected to form a 36, 2300/460 V trans- former bank.
