Q4A 208-V three-phase power system is shown in Fig(4). It consists of an ideal 208-V, Y-connected three-phase generator connected through a three-phase transmission line to a Y-connected load. The transmission line has an impedance of 0.06+j0.12 per phase, and the load has an impedance of 12+j9 per phase.
