A 4 kVA, 200/400 V, 50 Hz, single-phase transformer gave the following test results:

OC test (LV side) 200 V, 0.7 A, 60 w

SC test (HV side) 9 V, 6 A, 21.6 w

Calculate

(i) magnetising current and the component corresponding to iron loss at normal voltage and frequency

(ii) efficiency on full load at unity pf

(iii) secondary terminal voltage on full load at power factors of unity, 0.8 lagging and 0.8 leading
