8) The three-phase transformer has a rating of 500 kVA, voltages of 34.5 kV/480 V, and high side impedance of j100 Ohm. Calculate the high and low side per uint impedance. Primary base Z=(base V)?/base V (34500 V)?/500000 VA= 2380 Ohm primary pu Primary pu Z = 100/2380 = 0,042 pu Since the pu impedance of the transformer for the both side is the same, pu value of the secondary side impedance is equal to primary side pu impedance
