Solution for problem P12.3-2 Chapter 12.3
A balanced three-phase Y-connected supply delivers power through a three-wire plus
Introduction to Electric Circuits | 9th Edition
A balanced three-phase Y-connected supply delivers power through a three-wire plus neutral-wire circuit in a large office building to a three-phase Y-connected load. The circuit operates at 60 Hz. The phase voltages of the Y-connected source are Va 120ff0 V rms, Vb 120 ff120 V rms, and Vc 120ff120 V rms. Each transmission wire, including the neutral wire, has a 2-V resistance, and the balanced Y load has a 10-V resistance in series with 100 mH. Find the line voltage and the phase current at the load.
