Textbook Question

Chapter 12.7, Problem 6PP

For the Y-Y circuit in Practice Prob. 12.2, calculate the complex power at the source and at the load.

A Y-connected balanced three-phase generator with an impedance of 0.4 + j0.3 Ω per phase is connected to a Y-connected balanced load with an impedance of 24 + j19 Ω per phase. The line joining the generator and the load has an impedance of 0.6 + j0.7 Ω per phase. Assuming a positive sequence for the source voltages and that Chapter 12.7, Problem 6PP, For the Y-Y circuit in Practice Prob. 12.2, calculate the complex power at the source and at the find: (a) the line voltages, (b) the line currents.
