A balanced three-phase wye-connected generator has an internal impedance of 0.2 + j0.5 Ωper phase and the phase to neutral voltage is 220 V. The generator feeds a balanced three-phase wye-connected load having a load impedance of 10 + j8 Ωin each phase. The impedance of the line connecting the generator to the load is 0.2 + j0.8 Ωin each line. The a-phase internal voltage of the generator is specified as the reference phasor.1. Construct a phase equivalent circuit of the system.2. Calculate the line currents ILA, ILB, and ILC.3. Calculate the phase voltages at the load, VAN, VBN, and VCN.4. Calculate the line voltages VAC, VBC, and VCAat the load terminals.5. Calculate the phase voltages at the generator terminals, Van, Vbn, and Vcn.6. Calculate the line voltages at the generator terminals, Vab, Vbc, and Vca.
