Repeat Problem 11.39 with the load impedance Z_Y = 15 ∠ −60° Ω. By drawing the voltage phasor diagrams for the two cases, illustrate the effect of the load impedance angle on the voltage drop for a given line impedance.

Data from Problem 11.39

A three-phase, three-wire system, with a line voltage V_BC = 339.40° V, has a balanced Y-connected load of Z_Y = 15 ∠ 60° Ω. The lines between the system and the load have impedances 2.24 ∠ 26.57° Ω. Find the line-voltage magnitude at the load.
