In a balance three-phase system, the source has an abc-phase sequence and is connected in delta. The line connecting the source to the loads has an impedance of 1 + j2 22 per phase. There are two loads connected in parallel. Load 1 is connected in wye, and the phase impedance is 4 + j2 2. Load 2 is connected in delta, and the phase impedance is 12 + j9 2. The current lab in the delta load is 16245° A. Find the phase voltages of the source and the line currents. Write your values in polar form.

In a balance three-phase system, the source has an abc-phase sequence and is
connected in delta. The line connecting the source to the loads has an impedance of
1 + j2 № per phase. There are two loads connected in parallel. Load 1 is connected in
wye, and the phase impedance is 4 + j2 2. Load 2 is connected in delta, and the phase
impedance is 12 + j9 №. The current lb in the delta load is 16/45°A. Find the phase
voltages of the source and the line currents. Write your values in polar form.
