A transformer is rated at 2300/230 V, 15 kVA and 50 Hz. Assume that the transformer is operating at 80% p.f., leading and at rated output the secondary terminal voltage is 230 V. The following parameters for the transformer are given:

N1 = 1500 turns

N2 = 150 turns

r1 = 2.7 ohms

r2 = 0.024 ohms

x1 = 9.1 ohms

x2 = 0.088 ohms

In = 0.15 A

Core loss = 92 W

Calculate voltage regulation and efficiency of the transformer.

Please be as detailed as possible. I solved this problem but the examiner didn't give me marks for it. No matter how much I try I can't figure out my mistake. Now I am thinking if I have understood this topic in the wrong way. So please help me to solve the problem and final results of V.R. and efficiency will be very much appreciated since I can compare my answers with the correct one. Thank you.
