A balanced delta-connected load with a per-phase impedance of 30 + j10 Ω is connected in parallel with a balanced wye-connected load with a per phase impedance of 40-j10 Ω. This load combination is connected to a balanced three-phase supply through three conductors, each of which has a resistance of 0.4 Ω. The line-to-line voltage at the terminals of the load combination is measured to be 2000 V. Determine the power in kW:
(a) Delivered to the delta-connected load.
(b) Delivered to the wye-connected load.
(c) Lost in the line conductors.
