Draw a 3-phase wye-connected generator with transmission lines connected to a 3-phase delta-connected load. Assume the lines connecting them have an inductance of j5 per phase. The generated voltages are 120Vrms with phase 'a' having a phase angle of 0°. The loads are 10 Ohm resistors per phase. When drawing, make sure to label all 3 phases with voltage phasors, line inductances, and load resistances.

A three-phase substation bus supplies a wye and a delta connected constant impedance loads. The loads are connected in parallel. A three-phase feeder with an impedance per phase of Z = 0.6+j1.8 Q connects the loads to a source as shown in the one- line diagram of Figure below. The loads draw the following three-phase power: P1 = 35 kW S2 = 30 kVA pfi = 0.90 (leading) pf2 = 0.85 (lagging) wye connected delta connected The line-to-line load voltage is 480 V. Detemine: (a) the impedance of each load per phase, (b) the total line current flowing through the feeder, (c) the line-to-line voltage at the substation bus, and (d) the total three-phase real and reactive power supplied by the bus.

Two delta connected loads are connected in parallel and powered by a balanced Y-connectedsource. The smaller of two loads draws 10 kVA at a lagging power factor of 0.75 and the largerdraws 25 kVA at a leading power factor of 0.8. The line voltage is 400 V. Calculate a) The powerfactor at which the source is operating. b) The total power drawn by the two loads. c) The phasecurrent of each load.

A single phase, unity power factor load takes 90 Amps at 10 kV. Using a base voltage of 65 kV and base kilovolt amperes of 4475 kVA. Find the base current, base impedance, base power, per unit current and per unit voltage of the load.
