Q. 9: The resistance and leakage reactances of a 10 kVA, 50 Hz, 2300/230 V distribution transformer are: 12 = 0.0396N X2 = 0.158 N n= 3.96 N X1 15.8 N Subscript 1 refers to HV and 2 to LV winding.The transformer delivers rated kVA at 0.8 pf lagging to a load on the LV side. Find (a) The HV- side voltage necessary to maintain 230 V across load teminals. (b) The percentage voltage regulation. [Ans: (a) 2410 V (b) 4.78 %] Q. 9: The resistance and leakage reactances of a 10 kVA, 50 Hz, 2300/230 V distribution transformer are: 12 = 0.0396N X2 = 0.158 N n= 3.96 N X1 15.8 N Subscript 1 refers to HV and 2 to LV winding.The transformer delivers rated kVA at 0.8 pf lagging to a load on the LV side.
