Question: A balanced, positive-sequence wye-connected source has Van = 240 0 V rms and supplies an unbalanced delta-connected load via a transmission line with impedance

A balanced, positive-sequence wye-connected source has Van = 240 ∠ 0° V rms and supplies an unbalanced delta-connected load via a transmission line with impedance 2 + j3 Ω per phase.
(a) Calculate the line currents if ZAB = 40 + j15 Ω, ZBC = 60 Ω, ZCA = 18 - j12Ω.
(b) Find the complex power supplied by the source.
