P 12.7-5 A three-phase Y-connected source simultaneously
supplies power to two separate balanced three-phase loads.
The first total load is A connected and requires 39 kVA at 0.7
lagging. The second total load is Y connected and requires 15
kW at 0.21 leading. Each line has an impedance
0.038 +/0.072 f/phase. Calculate the line-to-line source volt-
age magnitude required so that the loads are supplied with
208-V rms line-to-line.
