Three single phase 50 kVA, 2300/230 V, 60 Hz transformers, are connected to form a 3-phase, 4000/230 V transformer bank. The equivalent impedance of each transformer referred to the low voltage side, Zeq, is 0.012+j0.016 2. The transformer bank supplies power to a 3-phase, 120 kVA, 230 V, 0.85 PF (lag) load, as shown below. a) Find the transformer turns ratio (1 point) b) Find the secondary current I, (2 points) c) Find the magnitude of primary current I, (1 point) d) Draw and label the per phase equivalent circuit at the high voltage side (2 points) e) Find the primary line-line voltage Vp (2 points) f) Determine the voltage regulation.
