Q5: A 30 kVA transformer has the iron loss and full load copper loss of 350 and 650 W, respectively. Determine the (i) Full load efficiency, (1I) 0.8 load efficiency, (iii) Output kVA corresponding to maximum efficiency, and (iv)Maximum efficiency. Consider that the power factor of the load is 0.6 lagging.
