Please show the solution and answers in each. Thank you. A 120 MVA, 19.5 kV generator has Xₛ = 1.5 pu and is connected to a transmission line by a transformer rated 150 MVA , 230 wye/18 delta kV Watts, and X = 0.1 pu. If the base to be used in the calculation is 100 MVA, 230 kV for the transmission line. a. Find the per-unit values to be used for the transformer and generator reactances. b. If the transformer delivers 80% of its rated capacity to the line at 220 kV, express the current in per unit. c. Find also the current in the genrator in amperes.
