A 100 kVA, 1000 V/10,000 V, 50 Hz, Single - phase transformer has an iron loss of 1200 W. Find the maximum efficiency at 0.8 power factor lagging if the copper loss is 500 W with 6 A in high voltage winding. Also calculate the corresponding regulation if the equivalent leakage reffered to HV is 10 ohms.
