Determine the power delivered to the delta-connected load, Electrical Engineering

Assignment Help:

Q. A balanced delta-connected load with a per-phase impedance of 30+j10  is connected in parallel with a balanced wye-connected load with a per phase impedance of 40-j10 . This load combination is connected to a balanced three-phase supply through three conductors, each of which has a resistance of 0.4. 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.
