Outstanding presentation. I'm a former electronics technician and engineer, electricity fascinates me to this day. How wonderful that Switzerland had the sense to preserve this piece of technological history and keeps it not only in working order but available for the public to view and enjoy and learn from.
The machine runs 3x for roughly 10 minutes, 3 or 4 times per year for the public to see. It's a museum piece, efficiency is not the goal here (if it was, it would have been dismantled a long time ago)
It may be small compared with the turbo-alternators that I operated and maintained in my former career, but it is a beautiful machine. It looks in great condition, and well maintained.
Amazing! and it LOOKS LIKE NEW! My old high school in Argentina, the Escuela Tecnica Otto Krause, maintains and runs a comparable steam generator every year. It is a bigger compound machine, made in Germany in 1913. It was used to provide electricity to government buildings in Buenos Aires, and remained operational as an educational and historical piece all this years. It produced short of 80 kW during the test run I attended to, dumped onto rows of banks of incandescent bulbs. The limiting factor is, I believe, the state of the rusty old boiler, which was not entirely safe at the working pressure (~12 kg/cm2).
Thank you to everyone involved in bringing these videos together. It's the first time in my experience the whole power generation sequence has been not only explained but shown as well.
It's been so long since I studied electromechanical systems, but it is changing magnetic lines of force cutting across the wires of a coil that produces electromotive force. This would require orienting your stator coil/coils 90 degrees into the plane of the drawing from what you've shown, with allowance of course for the shaft to pass.
Beautiful! I have spent over 40 years working on hydroelectric generators dating back as far as 1896 that are still in operation today. Many of the dams and turbines date back further, before the advent of AC.
You lucky buggar, that is so interesting. The local hydro plant here( Tully N.Q. Australia) had 4 X 17 or 18 Mega watts alternators before the upgrade, then after the upgrade the new Alternators have 24 Megawatts in the same size somehow with only one inch nozzles @ 2000 Psi, that's a scary pressure when you look at the size of the pipelines. Anyway I liked it before the upgrade because they had the Flyball governors out in the open just spinning around but now it's all electronic. You know how it is, progress isn't always a good thing but they did it for accuracy's sake & automation. Such an impressive place built into the side of a mountain.
Machines of the late 18 and early 1900s were so much more stylish than they are today. I used to work at 312 N. Spring St. in Los Angeles, CA on the 15th floor where one of two elevator rooms was stationed. Once in a while, the maintenance guy would do some work on the 1930s era equipment. I would poke my head into the room and look at all of the machinery, and it looked so good by today's standards. The same is true for this generator equipment. Very nice.
It looks cool and I love it , but there truly is no comparison between what we can do today compared to a century ago when it comes to machining or designing.
In the Netherlands a steam powered pumping station, which has been decommissioned a long time ago, is still being used as a backup for the new pumps. When there is high demand, it is fired up. So, a museum but still having an economical value. It’s the Wouda gemaal in Lemmer Friesland. You can visit it and once in a while it is powered up for maintenance and training. Being fed by coal at first but now oil burning.
a loot of mountains, a lot of streams, very small population, i would say its more logical than anything else, any country with identical condition does that, because its basically free electricity.
@@fanplant no. they probably indicate the operation of various things like the exciter. A synchroscope is a needle type instrument where basically put, 2 motors are connected together via a differential gear (like in a car). One motor is connected to the power plants generator, the other to the grid. Usually there are also light bulbs connected to indicate the phase angle error. When the generator is in sync with the grid, the needle of the synchroscope should be at the 12 o'clock position, and not move. There is also the option of the needle being stationary at the 6 o'clock position, which would indicate that the generator and grid are 180° out of phase. If the generator is tied to the grid with a phase error, the generator will be forcefully moved to be in sync. This will draw significant current as it tries to phase advance or retard in a single rotation to match the grid. If this happens the grid ties trip (basically big circuit breakers) and the generator is taken offline again. In case of the lights mentioned previously, they will be off when in phase and frequency, and brightly illuminated if 180° out of phase, and slowly oscillate from bright to dark by the frequency error, same goes for the synchroscope needle. Basically put, the grid ties engage all 3 phases simultaneously, else the generator will run out of sync and try to shake its self apart if the ties do not trip (overcurrent). If you want to see what that looks like, look for the video "Gen 1 Desync" by "GITsL9l". Its a short where you can see what happens when a generator falls out of sync due to the turbines (presumably) slowing down too much.
@@fanplant true, its unusual to see someone that knows what it is and how it works. My point with the switches below the lights and that one being lit all the time, still stands.
You know that was a great video with excellent details for those of us that know what we're looking at by that I mean showing us the ID plate and 215 Kva is way more power than I thought it was capable of. That is nearly capable of running a small town. Also very cruide voltage regulation and as you know it's done with an AVR (Automatic Voltage Regulator) these days. Such an impressive machine, I would really like to see it in person one day.
I am a electrical engineering graduate but I unable to understand fully ie 100% after watching 3 times, I can only understand around 70%, but I think u have done a perfect job on this video, my whole career profession is on factory operations management, I have more thing to learn on electric engineering.
That's beautiful and really well kept, another interesting topic would be syncronization to the grid or other generators but looks like it would impossible to show it with this one being disconnected
I'm building a 1:25 scale model of a Three Phase generator coupled with a 25mm pelton turbine, I was struggling A LOT trying to understand how to wind up the three phase coils. Your video is really helpful because it confirms my zig-zag hypothesis. I think I should put 4/5 wires for each phase and be able to turn on some 2v LEDs. A smaller cc motor will provide for the inductor coils, again, coupled with a pelton turbine
Old good alternator with DC exciter generator but to be honest there even were alternators getting excitation from exciter generator which also have even smaller sub-exciter DC generator. (Sorry if I named them wrong because English isn't my native language) I love All those old machinery and as an engineer I really admire by predecessors work. Isn't it a wonder having a weaker theoretical knowledge and less computational power ( logarithmic rule instead of modern computers) they made all things that power our world.
5:00 You are confusing phase voltage to line voltage. If that generator has 220V between its phases, then it has a phase voltage of 127 Volts and first it needs to be connected to a transformer.
Thank you! I'm still fascinated by ropeways, so there are good chances for another one to come up in the future! I usually have more contact with those in the winter (due to skiing), but I have several such projects in the backlog which are not that easy to get acces too. Let's see what the future brings 🙂
Sure the kid have been loving turning that power. Maybe he doesn't know but he has been "manipulated" in a good way to become an engineer. Great explanation and nice dad job in a same time
i might be wrong here, but the howling might be caused by eddie currents in the field coils, and they even out, im surprised the machine hasn't been kept as a backup generator
I was thinking producing steam with a parabolic solar-thermal generator during the day, saving it in a boiler, and using it at after sunset all through the night.
It's a nice vid, but I'd have been interested to understand how the speed and line frequency is stabilised. Not sure if it's just a straight mechanical regulator, or perhaps other special measures.
Perhaps part 1 (about the steam engine driving the thing) will answer your question. It illustrates a mechanical speed regulator that automatically adjusts the power level.
My area is powered by various sources of electric power, but since we're swimming in natural gas (Intermountain West), lots of it is coming from not coal gas, but natural gas. It's a good peak handling source.
very good, expert explanation.... the exhaust steam of the engine is just expelled in the air...Was the machine original not condensing the exhaust steam ?
@@barryphillips7098he wasn’t disputing that but steam power lived on into the 1900s. Some pumping stations were still steam Powered into the 70s before electricity took over
5:02 Isnt there a mistake? I just dont get how you can have in Switzerland 220V between phases and 230 between phase and neutral? With phase shift 120degrees, L-L voltage should be 1.73 of L-N voltage.
Switzerland has 230 V between L and N. But this generator has 220 V between L and L, which is unrelated and incompatible indeed. There is a transformer that was used when the Swiss voltage was changed.
Thanks! Appearently 60hz is more efficient for longer distance transmission, but I doubt that is the historical reason why international grids run at a given frequency.
@@caoimhin7122 While this would certainly be an interesting video, It wouldn't fit the "Mighty Machines" format unfortunately. In this playlist, I present actual machines from my own footage, not focusing on historical anecdotes.
11:31 in a more modern setting you would jump start electromagnet with a battery? But how do you connect the rotor to that battery ron ??? 😅 Preferably wirelessly somehow hihi 11:31
Just remember, since 1904 the ferromagnetic materials carrying the magnetic flux, improved a lot. Also, the formulas for designing electric transformers, motors and generators, were perfected. So, when you use an electric generator from 1904, the problem is not the steam engine, is the generator itself. In university I followed the specialization for designing electric motors, transformers and generators, so I know what I am writing.
Oh, wow! What a beautiful piece of old machinery! I suspect that it never looked this gorgeous when it was new. The restorers used different bright colors and polished it up, making it look new and shiny, only better. Added bonus... totally impervious to an EMP attack because it has no electronics to get fried. The keepers of the grid should go back to old school steam engines and steam driven generators, just like this one. There should be absolutely zero energy shortage, since North America has lots of coal to fire the steam engines with.
I can assure you that it looked just as as nice when was new, we even have the old photos to prove that. Sulzer were proud of there engineering and they wanted to show that.
I still have a pair of doubts. Does the mini-DC generator has a capacitor to smooth furthermore his current? And also I'd be glad to know or hear the story about how that variable resistor was manipulated in order to attend the demand of power during the day, we are so in between technology that I can't imagine that a man had to do that!.
Those large dynamos have many poles and all the coils are in some way interconnected, so the current should be reasonably smooth, also it feeds large coils which should behave as chokes and thus also smoothing out the DC.
Every metal surface is polished, everything else is perfectly painted and beautifully maintained! Very impressive display, and an excellent clear video on how it all works!
Not sure if you covered it in the first video, but steam engine are pretty bad backups, needing quite some time to start up. Did they keep a boiler under steam the whole time so the steam engine can be started immediately
They used steam in other processes on site, so they always had steam. As long as you have steam you can start such a steam engine in about 10-15 minutes from cold. But it is not great for the engine to be heated up so quickly.
Outstanding presentation. I'm a former electronics technician and engineer, electricity fascinates me to this day.

That generator is beautiful. Magnificent engineering and it's 120 years old.
They should use the resistor load to pre-heat the boiler water.
