All three legs are generally used for distribution.
That's unusual. All three phases are generally on each pole in populated areas. Some rural areas do have only one phase distributed down each road. It is uncommon to have all three phases run into a home, though.
Which HIS
Ahhh no answer to that, so just an A-H attack. How clever....
OHHH so now we are going from never, to "low likelyhood"?
I used to live in one of those locations. It had a for shit utility neutral.
Ahh.... yet an other A-H attack...... Your ability to have polite discourse is short of amazing, well well short of it.

That must have cost several pretty pennies.
I believe you are mistaken. Under the REA in the 1930s and '40s the nominal voltage was 135. Voltage drops over the long rural lines made variations significant - a short lane farm got 135 while a long lane farm might get only 100 with any load running. IIRC much of this was also 25 hz. (All early "niagara project" power was 25Hz - changed over in the early fifties - I can still remember having new electric clocks, and motors on washing machine and refrigerator being changed over when I was a wee lad on the farm in Ontario.
"long life" lightbulbs sold for urban use even a few decades ago were "farm bulbs" rated for 135 volts.DuroTest was a major manufacturer of
135 volt bulbs IIRC.Still common in Mexico (DuroTest in Mexico is now DuroMex)
Yeah, I should have been clear on how I said what I did. We live in a remote area, with the smallest parcel being 5 acres. There are larger lots, some of them as large as 60 acres. As a result, and the fact that it hadn't developed much until the past ten years, only one leg ran on the ridge. Growth necessitated the upgrade, but even then they had intended to run only two of the legs. The three phase terminates at our residence, and we are the only ones that are using all three legs.
I agree, having three phase run to a residence is not common, although I've had it at the last three locations. First one was open delta. Second one and this one are full blown three phase delta. Second one didn't cost us a dime----all we had to do was guarantee a given amount of use over a given amount of time. Wasn't so lucky here. It cost just over $22,000 to have it run to us. Worth every damned penny as far as I'm concerned. I have a
50 kw induction furnace that I want to run, to say nothing of my numerous three phase machine tools.Harold

Heh! I just commented on that in a different response. It cost just over $22,000. They had quoted me over $30,000 originally, before they realized they had to update the line. The time interval between the original inquiry and the one where I committed was several years. Glad I waited! We were still living in Utah, so it made no difference. We've had the three phase service for about nine years now. Very convenient. I've had such service since 1967.

Depends a lot on where you live. On the street where i grew up it could be had, but rotary converters were often cheaper. Most places i lived in the LA area it could be had from the local pole. Where i live now it is over 10,000 to get 3 phase.
I seem to remember reading that the early Niagara generators are indeed 25 Hz. Also that instead of trying to replace the generators they installed frequency/phase converters when they connected it to the grid. It seems that the AC generators were not economically rebuildable or replaceable. Now where was that article?
*Every* house I've ever lived in had 3-phase "on the pole". None had 3-phase service, though. My father wanted 3-phase service when they built their house in '59, but the power company wanted a minimum of $100/mo just to bring it down from the pole to the weather head. Wasn't worth it for him to work at home.
Not true in rural areas. The normal lines around here are single phase. There is a 3 phase line less than a mile away BUT it is a separate feed that heads up to the school. I was very lucky because a gent toward the end of the feed past my shop wanted 3 phase, He paid for almost 7 miles of run. I don't even want to think of the price that cost!!! That meant I didn't have to pay for it though.
MANY street transformers are single phase only in residential areas. The main feed would in all likelihood be 3 phase, with phases separated to feed different streets/loops. Getting 3 phase power to a building in areas like this is VERY expensive.
For SOME value of populated that may be true, but almost every where I have lived, has only singe phase on the poles, in residential areas. Nearest 3 ph to me is at least a half mile.

Are you sure? Perhaps it is just that way where you live.
Southern California distributes 208 ungrounded delta configuration in the industrial park I was in at my last job.
Sure they did. Where did you get your 120 volts from?
Our building used one of the phases to feed a step down transformer that supplied 240 center tapped secondaries to us for standard services. Any power supply we made that was more than 1kW meant that we could not use our standard feeds to test it, so we had to get one leg of a three phase feed fed into our lab, which we found to be not respective to ground.
So our "120" came from whatever manner the power company used to supply the entire area. Step down transformers with the center tap of the secondary grounded at the pole, and at the service entrance and panel. No big mystery.
Set your goddamned PC clock right, you absolute retard.
Id be happy to do just that. Or he can meet me in Orange County.

So hire me and find out for yourself.
