A balanced three-phase delta-connected source supplies power to a load consisting of a balanced delta in parallel
Question:
A balanced three-phase delta-connected source supplies power to a load consisting of a balanced delta in parallel with a balanced wye. The phase impedance of the delta is 24 + j12 Ω, and the phase impedance of the wye is 12 + j8 Ω. The abc-phase-sequence source voltages are Vab = 440 < 60o V rms, Vbc = 440 < – 60o V rms, and Vca = 440 < – 180o V rms, and the line impedance per phase is 1 + j0.08 Ω. Find the line currents and the power absorbed by the wye-connected load.
