A 50 Hz, three-phase star-star transformer is rated at 1300 MVA, 24.5 kV/345 kV. It has a per unit equivalent reactance of 0.115 pu. If the high-voltage side of the transformer is delivering 810 MVA at 370 kV, 0.9 power factor lagging, calculate:
V_base LV side = 24.5 kV. Z_base LV side = 0.462 ohms
V_base HV side = 345 kV. Z_base HV = 91.56 ohms.
