Find the real and reactive powers per phase, Electrical Engineering

Assignment Help:

Q. A 345-kV, 60-Hz, three-phase transmission line delivers 600 MVA at 0.866 power factor lagging to a three-phase load connected to its receiving- end terminals. Assuming that the voltage at the receiving end is 345 kV and the load is wye- connected, find the following:

(a) Complex load impedance per phase ¯ ZL/ph.

(b) Line and phase currents.

(d) Total three-phase real and reactive powers.
