question

A 10-kVA, 2400-240-V, single-phase transformer has the followingresistances and leakagereactances. Find the primaryvoltage required to produce 240 V at the secondary terminalsat full load, when the load power factor is (a) 0.8 power factor lagging (b) 0.8 power factor, leading. r_1 = 3.00\Omegar_2 = 0.0300\Omega x_1= 15.00\Omegax_2 = 0.150\Omega.
