- Part 1: Generators at the Historic Folsom Hydro Power House in Folsom, California. Tour with Power House Docent Bill Henning. Learn about the forebay, see the turbines, see the original generators built by Elihu Thomson at GE. This powerhouse preceeded the Niagara Falls installation by Westinghouse. Part 1 of 3 videos on the Folsom Power House.
It's so nice to see that Edison himself is still giving tours of his former power generation plant.
Lovely old guy, probably older that the plant. "Here we have the permanent magnet..." *shaky hand points to a field coil*
Stay tuned this winter for more videos on other early power sites by GE and Westinghouse!
I'm glad this video reminded me of this place.
I live a few miles away, and want to see it in person.
Also exlplains what I see when I drive by, or paddle my kayak up the river there.
The wall at the dam still remains, and is obviously very old, but the forebay is gone, so did not know what the wall was for, until now.
Very cool video, and love the nice man explaining things, even though he made a few mistakes.
This seems kind of old school but more people really need to learn and be able to do the formulas and basic engineering for AC and DC generators/motors. These days with more electric cars, solar power and other things becoming more common we need to absorb basic info so we can take full advantage. Learn about phases and how they work. How to control them. How to pick the right motor and battery. Get past the marketing voodoo. 20% of all people on Earth need to know these things.
And critically the people where it matters need to understand the infrastructure required to make widespread vehicle electrification viable
Very interesting,,,love history,@ bill love you're voice also,,it's soothing and calming!!!!!
The turbines were horizontal, driving the horizontally mounted generators. (You can actually put your head inside a turbine through a cutaway.) The govenor of one generator failed, causing an overspeed that resulted in it exploding due to centrifugal force. The man on duty was in a phone booth there and was not injured. To this day you can see parts of the generator imbedded in the vaulted brickwork overhead, two stories up.
Search Folsom Powerhouse State Historic Park for hours.
How did the governor keep it working at the right speed? This place would be interesting to visit!
I visit this place still. old family go-too as a kid. The curator was off on a few points. The dc field generators were 500 amps not watts. And the 3 phase generators were not 750 watts.
Cool you caught all that and that you know the specs. Thanks.
What a fascinating lecture. What I wanted to know is did the powerplant have to stay in phase with other plants on a grid, or was it a self contained system? The other question would be how did they balance the load to keep the voltage from leading the phase, or did they just burn out generators like our example here?
Zyworski , this plant would have operated by itself, as there was no power grid in those days. Voltage is controlled by varying the DC excitation to each AC generator field. In an AC system, voltage will normally lead current due to reactive load such as transformers and motors.
Back in WWII, Trustees from Folsom Prison Operated Water Cooled Browning M.G.'s Positions. Because They Were Convinced that the Japanese Were Going to Bomb Both Hydroelectric Power plants. Since They were A Strategic Target. It ( Folsom Power Plant ) Had Originally been The Sole Source of Electricity For the State Capital.
Edison tech center showing Tesla's invention, 🙂 something great in 2020
Tesla invented hyperbole
absolutely beautiful setup!, now to get in there and complete the restoritive process, almost sacreligeous to leave dangleing wire, and burned out switches, almost looks like a rank amatuer tried to put the place back together and had no clue or ran out of parts
Were these type of power houses (water powered) common in the US in the early period of electrification..?
In a word yes. Once in place the “fuel” was gravity. Go west and tour grand coulee dam. The older turbines are 80 years old. But much older smaller systems abound
I thought the old fellow had mixed up watts and amps. hope I am as in good a shape at his age. I first thought that on the 750 watt gensets, way different 750 amps. I just wish I had saved the one at dryden washington, that powered wenatchee, it was still perfect when I saw it with all the guages and gensets through ww1. now gone, sob.
Paublus Americanus , I believe he meant to say 750 Kilowatts each. That would make sense if the turbine driving it was rated at 1200 horsepower.
Great video. Thanks for making and sharing it.
I wonder why they put the field windings in the stationary position while running all the power through slip rings and brushes? Modern alternators always put the field windings on the rotor and the stator windings generate the power, which never has to go through a moving connection.
Ethan Lamoureux , he mentioned that the generators were adapted from DC generators. So, it makes sense that the field coils were left as they would be in a DC generator, and the armature redesigned for the AC coils and skip rings. That is also the same configuration that is still used for a wound rotor AC (synchronous) motor.
I wished I knew about all this stuff better.
I wonder if a team of average electrical engineering undergrads would be able to figure these things out and get them working again, Mad Max style.
Thank you sir,,for the information
Only 500 watts from the giant DC generator? I got a couple of solar panels that can do that during the day time. It would seem that being such a large DC gen it would make more power than that? Hmmm?
What powered the field of the field generator.
maynardr6: From what I could discern, they had to use a separate AC alternator to generate the current for the field coils. If that is so, it is a very inefficient system, using a generator to run another generator (generating the exciter current for the field coils in order to create the alternating/rotating magnetic field).
@Erzahler
The DC generators shown in the later part of this video are what generate the power for the field windings of the main alternators. Field windings in an alternator require DC, which could not easily be created from AC since they didn’t have rectifiers. But it appears that what maynardr6 was asking was what powered the field windings for the DC field winding generators, and the answer is as Rick Delair wrote, they are self-powered by the generator’s own output and started via residual magnetism.
The DC generator is a shunt wound machine. The stator (stationary) coil is connected in series with the armature (rotating ) coil. Normally these machines retain a small amount of residual magnetism from previous operation, which is enough to allow it to build voltage as the generator starts to rotate. In the event there is no residual magnetism, batteries can be used to momentarily energize (flash) the generator coils which restores the magnetism.
All power plants have dc generators that provide exciter power for the main generators.
👍👍👍👍👏👏
"3-phase split rings.."?
Pretty sure he meant to say "slip rings".
rather see them in action.
I always think it is SO AMAZING how so soon after the "Discovery" of electricity we developed machines to handle and generate it in such magnificent fashion. These machines were made to last a literal lifetime and beyond. There seemed no end to the creativity of the machines that were produced so early on in our affair with electricity.
Mr. Nikola Tesla should have been treated like a GOD instead of being MIS-treated by the Greedy Rich Corporate Assholes of the day. It's a Disgrace how he was treated and it angers me that it was ever allowed to occur. Mr. Tesla (whom several times wished many of his inventions would serve humanity for FREE) should have died an unimaginably wealthy man ! Instead of poor and alone. Its an absolute disgrace. The corporations that are still in existence because of his ingenuity should continue to generate massive amounts of money from his early work...to this day! They should be ashamed of themselves...lotsa luck I guess.
Someday I will write the "Adult Version" of American History... Bet its a Best Seller !
+SquillyMon Thomas Edison really screwed over Tesla, but Westinghouse worked with Tesla to produce alternating current. It begs the question why he died poor if he teamed with Westinghouse. There was no excuse for the mistreatment of this genius of a man.
USNVA
WHY? Cause Tesla tore up a contract that Westinghouse owed him a certain amount of money per every Kilowatt his generators produced....it was worth BILLIONS... He tried to share his gifts with the world and capitalist robber barons just took him for all they could and profited from it...and never shared it with him. They watched him die alone and poor. ASSHOLES
SquillyMon I hope you're not getting the impression that I'm disagreeing with you because I'm not.
USNVA
No no... I didnt get that impression. The thought just angered me for how they treated him. Its a DISGRACE...and it continues.
Yes it is a national, ney international disgrace that Tesla was treated the way he was! It was the price he had to pay for disagreeing with the "establishment" of the day. Tesla was way ahead of his time in terms of his inventions, theories and applications. The worst of it was that many of the "establishments"of Tesla's day thrived off his hard work and gave nothing back to him for it! Bloody disgrace! Hope they all rot in Hell!
This gen station seem to be an overkill for a prison complex.
That Old sparky (electric chair) takes lots of juice
Way overkill. And same with a prisons for such a small population at the time.
All for just a few lights
This plant supplied power to Sacramento. As mentioned early in the film there was a smaller plant upstream that fed the prison.
MOTOR MAGNÉTICO CLOVIS. É o cão.
Excellent explained, VERY POORLY filmed
DC good
educational. i wish the old guy didnt stutter so i could absorb more info. lol
annoying narrator
AC bad
Nah
Look what happened to Edison
He’s dead and they don’t use dc current for houses.
@@demetrijohnsonssirenvideos3590 which is strange as most devices rectify ac to dc, could leave out a lot of steps when solar powered from your own roof, some ac device(s) can be directly powered from a dc source ... less work for the convertor.
@@jyvben1520 well I mean for long range transmission of DC current, it’s a lot harder to do than AC.
