In a balanced three-phase system, the source has an abc-phase sequence and is connected in delta. There are two parallel wye-connected loads. The phase impedance of load 1 and load 2 is 4 + j4 and 10 + j4N, respectively. The line impedance connecting the source to the loads is 0.3 + 30.2 12. If the current in the a phase of load 1 is Ian, = 10/20° Arms, find the delta currents in the source.
