Three single-phаse trаnsfоrmers аre cоnnected tо make a three-phase Y- ∆ transformer bank. The three-phase transformer bank is 2400 V primary (Y) and 208 V secondary (∆), i.e., 2400/208 V. The transformer impedances are: R1 =0.30 ohm, X1 = 0.65 ohm; R2 = X2 = 0.0 ohm. Note subscript 1 is primary (Y) side, subscript 2 is secondary (∆) side The transformer is fed by a three-phase generator (Y connection) whose output is 200 kW at 2300 /30θ V with unity power factor. Determine: a) The transformer ratio (10 points) b) The line and phase voltages and currents at the transformer primary (2400 volts) terminals. (20 points) c) The line and phase voltages and currents at the transformer secondary (208 volts) terminals. (20 points) Note: terminals are the input and output connections Make sure that you include the angles for all quantities, even if it’s 0 degrees. Write your answers for b & c in a table like the one below Side IL IP VL VP Primary Secondary
