A 50 MVA, 230 kV (WYE) / 23 kV (DELTA) three-phase transformer has the following parameters R1 =0.30 ohm, X1 = 0.65 ohm; R2 = X2 = 0.0 ohm Assume the core has infinitive impedance. Note, subscript 1 refers to the primary 230 kV side. At the 230 kV side a three-phase Y load is connected. The voltage at the load is 220 kV at 30 degrees, and the load absorbs, current flow at the load, is 5 kA amps at 0 degrees. What is the magnitude of the voltage at the 23 kV, terminals? Enter your answers in kV, thus 23,206 V @/15 degrees enter as 23.21 Note that the word kV is not entered, just the numbers, enter two decimal places.
