= Figure Q2 shows the exact equivalent circuit of a 50 Hz, 30 kVA, 2200 V/250 V single- phase transformer. Given that Rp = 0.9, Xp = 2, Rc 10 ΜΩ, Χm 13 ΜΩ, Rs 0.0094 , X = 0.038 2 and iron losses at the rated voltage is 10 kW. A load with 0.8 lagging is connected to the secondary circuit of the transformer. - (b) - (a) Draw the approximate equivalent circuit referred to primary and calculate the equivalent winding resistance and reactance referred to primary. Based on the circuit parameters calculated in part (a), determine the full load efficiency.
