Hello to everyone who's reading. :)
I hope I posted this in the right place; while this is not exactly a homework problem, I am trying to improve my understanding of the background information before proceeding with course-style problems.
This post is because I'm trying to fully understand the fundamentals of the topic of three-phase electric power setups, but I feel like I don't fully get it, despite searching online for several days.
The Attempt at a Solution
Basically, here is what I believe I do understand.:
- The three lines can be connected in a Wye / Y configuration or in a Delta / Δ configuration, like shown in the WyeDelta.png image.: (There can optionally be a fourth line that's neutral in a Wye / Y configuration.)
- Somehow, there are three power sources, and those power sources are are plus or minus 120 degrees out of phase from each of the other two power sources. (Here, I use the word "somehow" to emphasize my third confusion (shown below - not the #3 directly below, but the one in the next section).)
- A change in magnetic field induces current (by producing an electromotive force across the conductor in question).
- Magnetic fields are produced by moving charges, which includes electric current.
- Are the three coils that surround the magnet (for example, as in the image Three-phaseElectricPower.jpeg) or are surrounded by the two magnets inductors (as I've seen in another source)?
- If the coils that surround the magnet or are surrounded by the two magnets are in fact inductors, then are their impedances just ignored because of it not mattering due to voltage sources delivering the "promised" voltage anyways? In other words, do the impedances in the 3-phase_flow.gif image only represent the impedance that is not present at the site of the electromagnetic induction / magnetic induction?
- How does the generator start? Do the three power sources start the rotation of the magnet or does the rotation of the magnet start the power providing of the power sources? Or, what else?
