SOLVED: Three single-phase, 50 kVA, 2300/230 V, 50 Hz transformers are connected to form a 3-phase, 2300/230V transformer bank. The equivalent impedance of each transformer referred to low voltage is 0.03 j0.02 2. The 3-phase transformer supplies a 3-phase load, 120 kVA, 230 V, 0.9 p.f (lag). Determine (a) the transformer winding currents. (b) the voltage regulation. (comment on the obtained results)

SOLVED: Problem 1 (25 points)Three single-phase 50 kVA, 2300/230 V, 60 Hz transformers are connected to form a three-phase 4000/230 V transformer bank. The equivalent impedance of each transformer referred to low voltage is 0.012 j0.016 Ω. The three-phase transformer supplies a three-phase 120 kVA, 230 V, 0.85 PF lagging.a) Draw a schematic diagram showing the transformer connection.b) Choose proper base values and convert to find the per unit equivalent of the system.c) Determine the transform
