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 120 Vrms 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.

Suppose you have a three-phase generator that provides 120 Vac per phase and works at a frequency of 60 Hz, this generator can be connected in both delta and star. Also consider the following 6 load impedances, which will be connected at the same time to the generator as follows: ZA, ZB and Zc are connected in star, while Zp, Zg and Zp are connected in delta. j20 j3n Za j20 ZA j30 j3n -j20 j 30 -j20 Zo -j20 ZE j30 -j2n j 3n. ZF Assume the generator is star-connected with neutral, calculate total system power, total power factor, and current in neutral.
