A 1 kVA single-phase step-down transformer is connected to a 220 V,

50 Hz A.C. source and delivers power to a load. The winding resistance and reactance at secondary side are 0.02 Ω and 0.1 Ω respectively. The maximum value of core flux is 0.248 mWb and the secondary winding contains 1000 turns. Evaluate


a. the voltage induced on the secondary side; (2 marks)
b. the turn ratio of primary side to secondary side; (2 marks)
c. the rated current on both sides; and (2 marks)
d. the winding resistance and reactance at primary side if the equivalent resistance and reactance referred to the primary side are 0.58 Ω and 4.7 Ω respectively. (4 marks)
