3. The resistance and leakage reactance for the high voltage winding of a 25 KVA, 2000: 200V, 60 Hz, single phase transformer are R1 = 0.6 ohm and614141c8d47ff.jpg = 1.8 ohm, respectively . On the other hand, the resistance and leakage reactance for the low voltage winding are R2 = 0.006 ohm and614141f9d0577.jpg = 0.018 ohm, respectively. Neglect the exciting current of the transformer. Select a base of 25 KVA and 2000 V for the high voltage winding.

(a) Compute the per unit values for the resistances and leakage reactance for the two windings. (10%)
