A 3-phase 480-volt circuit has a positive-sequence y-connected source and supplies a delta-connected load. The impedance of the lines between the source and load is negligible. The angle of vab is 0/ and the phase impedance of the load is 20 - j8 ohms. A) draw the circuit. Label the value of the phase voltages at the source. Label nodes a, b, and c. Label the line currents ia , ib , and ic. Label the l-l voltages at the load: vab , vbc, and vca. Label the phase currents at the load: iab , ibc, and ica. B) determine the phasor values of the l-l voltages at the load. Draw the closed voltage phasor diagram for the system, showing all l-l and l-n voltages. C) determine the phasor value of the line currents. D) determine the phasor value of the phase currents in the source and the load. E) calculate the complex power s that is consumed by the load and draw the power triangle. F) what is the power factor of the load?.
