Why 3 Phase Power? Why not 6 or 12?

Power Transmission Engineer Lionel Barthold Explains how 3 phase, 6 phase, and 12 phase power works, advantages, disavantages, and hopes for the future. Rotating phases, form an anisotropic tube. He worked on experimental 6 and 12 phase power lines at his company Power Technologies, Inc. before it was sold to Siemens after a long successful career. The experimental polyphase lines were located in Malta, New York, not far from company headquarters in Schenectady.

An Edison Channel explaining a Tesla idea.

Tesla used 2 phase, not three, most three phase devices first came out of Europe. Tesla did not invent AC either, Ferranti, Siemens, etc made the first monophase AC devices while Tesla was still learning math 101 in school. Hope this clarifies the myths you were told.

[Jonathan Weber]

What Tesla did was popularize and implement AC power generation and AC distribution, An idea that Edison was strongly against.

So the irony is that an Edison video, who was strongly against AC, is about a method of AC power distribution, who his rival, Tesla, popularized.

So yeah, Tesla may not have invented AC, but "An Edison Channel explaining a Tesla idea." Seems an apt enough description.

[EdisonTechCenter]

The primary dynamic of the 1880s was not a personality war between TE and NT, as what pop science shows you today. It was war of patents, large and small corporations. There is so much more to it than what modern media has fed you. Please use books on the era as opposed to BS websites and television focused on personal dramas, which oversimplify history and the AC DC story.

This why we need old folks around .

This dude is cool

Tesla developed 2 phase power systems. Before Tesla Siemens was working with single phase.

@quang dinh: thanks, you are right!

wiki :: Two-phase_electric_power early 20th century, imbalanced, less efficient --> not be used in generation / transmission nowadays

@ETC: do you mean Tesla invented this one ?

[DeutcherKonnig]

I wish the guy would have shown a motor under varying load in a side by side comparison feeding it 3 phase and 6 phase. Would smooth and continuous output difference be huge evident or subtle?

[J Suparman]

@ETC: as far as I know, there is never there 2 phase electricity. For such thing, generally everybody call it "1 phase". Sorry if I said the opposite opinion.

it was a slow day on youtube yet my IQ has gone up, cheers for this vid

He's old, leave him alone.

"And no one was surprised." Once you work out the math no one will be because you'd all be tired. haha.

This is beautiful
