Question:

Obtain the total average power for the unbalanced, Y-connected load in Problem 11.13, and compare with the readings of wattmeters in lines B and C.

Data from problem 11.13

The Y-connected load impedances Z_A = 10 ∠ 0° Ω, Z_B = 15∠30° Ω, and Z_C = 10 ∠ −30° Ω, in Fig. 11-32, are supplied by a three-phase, three-wire, ABC system in which V_BC = 208 ∠ 0° V. Obtain the voltages across the impedances and the displacement neutral voltage V_On. $A B 208/120 V 208/0 _V I 15/30 _Q 10/0 Q 10{-30 _Q$
