4. A three-phase three-wire system has a balance Y-connected load with a 75 2 resistance, 125 mH inductance, and 55 UF capacitance in series from each line to the neutral point. Assuming positive phase sequence with V, =125 V at 60 Hz, find the line current, the total power taken by the load, and the power factor of the load.

4. A three-phase three-wire system has a balance Y-connected load with a 75 2 resistance, 125 mH inductance, and 55 UF capacitance in series from each line to the neutral point. Assuming positive phase sequence with V, = 125 V at 60 Hz, find the line current, the total power taken by the load, and the power factor of the load. 5. A lossless neutral conductor is installed between nodes n and N in the three- phase system shown in Fig. 12.31. Assume a balanced system with (+) phase sequence, but connect unbalanced loads: Zy = 8+ j6 N,Z„y = 12– j16 N, and ZCN = 5 2. If V =12020° V and R, = 0.5 S, find ILN an rms
