In a balanced three-phase wye-wye system, the source is an abc -sequence set of voltages and V an = 120 30° V rms. The power absorbed by the load is 3435 W and the load impedance is 10 + j 2 . Find the two possible line impedances if the power generated by the source is 3774 W. Which line impedance is more likely to occur in an actual power transmission system
