A balanced three-phase source with a 13,800 V rms (line-to-line) is delivering power to a balanced delta-connected load with phase impedance Z1 = 10 + j 10 Ohms in parallel with a balanced wye-connected load with phase impedance Z2 = 8 + j 13 Ohms. Draw the electric circuit. Calculate the active (real) and reactive (imaginary) powers delivered by the source. What is the power factor of the combined load? Draw the power triangle.
