In a balanced three-phase system, the source is wye-connected and the source voltage of phase A is Van = ∠ 120 20 V. The load consists of two balanced wyes in parallel with phase impedances of 8 + j6 Ω and 12 + j8 Ω. If the line impedance is zero, find t
In a balanced three-phase system, the source is wye-connected and the source voltage of phase A is Van = ∠ 120 20 V. The load consists of two balanced wyes in parallel with phase impedances of 8 + j6 Ω and 12 + j8 Ω. If the line impedance is zero, find the line currents and the phase currents in each load. (Hint: use per phase analysis, then do angle shift for each phase.)
