I'm 72 and been working with 3 phase stuff since I was 18....never get tired of videos about how all the power gets to the end user....nice sound....excellent video...!
Doug Ankrum they have a lot going on.
What's the software they are using for designing.?
Yes, been here only for the nice music.

After 40+ yrs as an electrician, I am still amazed at the simplicity of the AC transformer, and how absolutely essential it is for electrical distribution and utilization.
The transformer in the video will convert megawatts of energy every day all day for years. No moving parts; just the steady 50/60 cycle hum of building and collapsing magnetic fields.
They’re incredibly efficient, some can be as high as 99.8% efficient. The only moving parts are the on-load tap changes (OLTC) used to compensate voltage changes by adjusting the turns ratio.
God's Mercy
Can someone tell me why they taped it my brain is very smole to process
@@mellowtag4875 Keeps the conductors bound tightly together. In reality, everything is vibrating at 50 or 60hz, it wouldn't take long for the insulation to wear through. Epoxy and Tape hold things tightly in place.
@@6502Assembler THANKKKKKK UUUUUU SIRRRRRRRRRRRERRRRRRRREEEEEEEEEE
This is the first time I have watched an assembly such as this. I have watched the smaller , Pole Transformers being made and even the Pad Mounted units BUT I have never seen something like this.. Fascinating to watch and a very enjoyable and informative video. Many thanks for allowing this to be shown online.. Incredible engineering..

Really outstanding video! Lets you see exactly how complicated and precision those big transformers really are! Great job!
*
I used to work in a factory that made these, including the big ones. They are made by hand. Every wrap of wire, every one of the thousands upon thousands of thin metal plates is placed by hand as shown in this video. It was incredible.

Back in the late 80s I was working as a Craftsman for a very large oil company (I won't name them) in a very large refinery. We needed a backup transformer for the refinery, so the engineering was done and the transformer was ordered. I think this one came from Germany. It took over a year for it to be built and shipped and it arrived on a special rail car. It was enormous and cost millions. It was installed and tested. It browned out the refinery on the first and every test that followed.
The scuttlebutt was that our electrical engineers had missed on their calcs and undersized the transformer (that's why I didn't name the company). There was an effort to blame the single female electrical engineer in the group, but eventually they had to admit that it was a team effort and everybody had signed off on the design. No one got fired, but if we had problems with the main transformer we had a plan where certain units in the refinery had to be shut in or dialed back until we could regain full power.
They are magnificent beasts (even the CTs) and if they're cared for properly, they can last for decades.
Mysterion, they may have had the same problem as I have encountered. I used to work for a large diesel engine dealer - we sold megawatt-sized generating plant to mining and mine site construction companies. One in a while we would get told that the genset would refuse to accept the load. On investigation it would turn out that they had (say) bought a 10 megawatt genset and connected it to a 10 MVA transformer to feed a few HV feeders. Sounds ok, but depending on how it was previously shut down, the starting inrush current into a transformer can be many times the rated continuous current.

Impressionado!!!! Mas que trabalho lindo!!!!

WOW I enjoyed watching this ☺
The On-load tap changes look like a nightmare to wire up, excellent video!

ABSOLUTELY AMAZING
Não canso de ver este vídeo, confinamento de três bobinas, OLTC, e seus dispositivos de proteção, tudo calculado para um dielétrico com a finalidade de suportar e transverter potencia e tensões elevadíssimas.

Outstanding.
Thank you.
Trabalhei por 14 anos em 2 empresas de transformadores , antiga trafo , agora weg e a asltom agora GE. Boas lembranças

يارب نشوف مثل هذه الصناعات في بلدنا بدل الحروبات والأجئ يارب حسن أوطاننا ..... .....
great job ! ! !
Woooooow, it was totally amazing!
Ну вот, теперь я хочу там работать :(
Absolutely brilliant
Amazing video! I knew there was a lot of technology and materials involved, but this video really brings home to complexity of these multi-million dollar cost devices! Should we experience another Carrington Event, those engineers will be in very high demand worldwide!
ㅃ
Carrington Event - People I knew involved in lightning arresters often rage at the omission of "their important role in protection against voltage spikes are not recognized" .. They seem to say that if the owners of these huge transformers would pay due respect to their profession, technology and contribution, to install adequate and proper protection, there is no reason to despair here .. They say that somewhere out there along the transmission lines will certainly face calamity, but for big ticket items like these transformers, proper voltage surge protection, followed by fast decoupling,s should have been carefully provided and not a reasonable concern.
I don't know .. I only know that we have come to learn many voltage related failures .. and my friends would say, that is exactly it .. You see only the wrecked cars disasters on the highway, but thousands, or millions, cars driving by, you see nothing .. If only people could see how many disasters we have successfully saved .. Your thoughts ?
@@kingstonchi From what I can gather most major installations use Metal Oxide Varistor protection, which has the advantage of capping transients very quickly, especially lightning strike associated transients. The problem here is that such MOVs have a distinct "lifetime", and an external (Carrington-like) event may overwhelm such protection systems, both in terms of impulse characteristics, and induced currents. Transients arising from lightning termination to conductors tend to be pretty short-duration, whereas the Carrington Event was a much longer-duration "onslaught", and designing affordable protection systems to mitigate this would be difficult at least.
@@phils4634 Thanks for the response. Agree that blowing the arresters to bits will probably just get started .. not that itself matterd so much .. but that does not remove the malady from the system, and to the transformer, is really the issue. At medium voltage level, there are "quarter cycle fuses" to isolate quickly, but not at transmission voltages .. There had been talks about attaching, basically explosives to bus bars at isolation length and ignite them electronically to disengage quickly .. Never heard again ..
@@kingstonchi This is why I mentioned "affordable" protection. Lightning terminations to energised lines tend to produce transients lasting maybe a few hundred milliseconds (line oscillation effects), but the bulk of the damaging voltages will subside within a few millisec. The Carrington Event produced the equivalent of "network-wide" lightning strikes, lasting for hours, and there's no realistic way of protecting against that apart from line isolation. The amount of induced current was amazingly high, and bearing in mind that long lines act as inductors, any sudden break (eg opening a SF6 breaker) is going to produce such a voltage spike that the breaker will certainly see flashover, resulting in significant damage. Using "no-volt" disconnectors will be ineffective since again the voltage is enough to arc many metres, with resulting "interesting effects" on surviving protection systems. There have been some proposals for protections systems but once the cost of such systems (for maybe a "once in 100 lifetimes" events) is determined, interest rapidly fades! :-)
Masterpiece! 👍
Wonderful! Thanks for share.
⚡️👍🏻
Круто, но было бы лучше, если закадровый голос объяснял бы что делают на каждом конкретном этапе
В таких видео, лишние слова излишни.
Да вроде бы как на протяжении всего видео есть подписи на интуитивно понятном славянском (чешском, вроде) языке
Василий Шумейко згідний що чеський , але їх слова не завжди поймеш.
Fascinating
Хороший обзор, сам раньше работал на трансформаторном участке завода, занимался ремонтом и производством трансформаторов, правда раза в 4 поменьше чем этот.
У нас тоже есть такой участок, только сейчас там обмотки не мотают, меняют на готовые, которые приходят с завода

@@usver_true это где это так замену производят?
На каком заводе вы работали?
Good Job 💪👊👍
Oh just found out it's a Croatian factory making HVAC transformers for electrical power lines I used assembled transformers but mine were minnows to these all things possible just timing and skilled staff.
YOU ARE WRONG, THIS is ETD TRANSFORMÁTORY, a.s., in Czech Republic.
zagrebtrans (seen by the end of video) is croatian heavy transport company, this is czech company, all graphics are in czech language, but croats do make such transformers too: kpt.hr/en/
Excelente video solo falto una breve explicación estaría perfecto.

Thank you very much! But was the guy who designed the tape winder at 2:00 told it would have to last a few centuries, or did he just have those gigantic gears hanging around?
ONCE AGAIN a well done video with not a whisper of what is going on.

Super Video.

The development of civilization is non-linear... A big jump may be replaced by very long stagnation.
We either learn to live on other worlds or we stagnate. We are young adults as a collective species so and there is no longer enough to go around on this one world. It's time to give this world a rest and settle other worlds.
According to your post _2170_ will be the best year ;-)

@@Tephodon it can also taper-off, reach plateau and then stay there, or even go backwards. what humans can do has its limits.
can you say where is this exactly? subtitles please
Something of note, is the size of the product built limited to the width of the train track?
Awesome video - please could you do another video a bit slower and with subtitles outlining what is happening - please!
Slow it down yourself, click settings/speed. As for subtitles outlining what is happening, what is happening is they are building a transformer. Were you born this stupid, or has a life of watching RUclips made you this way?
@@hamentaschen Wow, which bully took your lunch?
Мне музыка очень понравилась)
Bautifully made, a work of art.
The weight of these must be enormous.
Motivational video nice sound therapy
*_That was rather 'shocking' to see a transformer bigger than some houses..._*
Рождение трансика⚡. Класс автору за видео👍!
Вот так трансформатор, целый вагон занял! Ещё бы немножко побольше был - вообще бы не поместился. Масштабы впечатляют.
Так его специально в таких габаритах делают, чтобы в вагон поместился. Наши трансформаторы (сопоставимого напряжения) в вагон не влезают, их перевозят тралами с перекрытием дорог
Flower power ! Thanks 4 vid
es increíble ver como se fabrican estos enormes transformadores

Just imagine how many 6L6 output tubes it would take to drive this transformer to full output. Far out.
En Colombia necesitamos teransformadores alta potensia y ahorrador enerjia subestación que sea aceite de petrolio más limpió
This things also blow up occationally. They are oil cooled. There is an oil purification system to remove moisture that tends to be absorbed by the oil in pockets. If the transformer is powered off and cools, that's when the danger can happen. (Personal experience) On pre-start up the oil is heated for a few days to drive out the moisture. However, sometimes pockets of moisture do not get removed and when power is applied...ka-boom! That's why there are thick reinforced concrete barriers around the transformer.

Thank you for this video, I want to ask, may I use it in my presentations? I am working in the Test and Measurement industry and this will help a lot for the guys to see the inside and also why they test what. But I would like your permission first before I use it. Many thanks and hope you find it in order

Amazing to watch. What is the rating of this transformer?
Very fine video...
Where is this??
Please
Tell me.
Интересно, что компания ETD TRANSFORMATORY относится к Шкоде, а на электровозах ЧС4 (ŠKODA 52E) стояли словацкие трансформаторы фирмы BEZ
Impressive! Does anyone know if & how new designs might be tolerant to CME events?
Daniel Wahl - Seriously ?
@@haraldpettersen3649 Yes it is a real concern. AND I am interested. Why do you question?

Great audio and video to make your point. Thanks for not having a hip hop soundtrack.
Is that brown stuff cardboard? its interesting that so much of it goes into these things
wow so big. I wish there were more explanations included.
Made in Czech Republic, in Plzen (western part of Bohemia)
WTF .. this is huge and perfect!
So these are giant linear transfromers, with a very low efficiency, are there also Giant versions of high frequency transformer, e.g. Push-Pull transformers at 45kHz?? is it even possible?
Cool thank you, is this from Poland I’m not quite sure but I think it is.
The Czech Republic.
felicidades excelente trabajo y donde estan su pagina web o contacto por si requiero presupuesto?.

What's different between a normal Transformer and Power Transformer?
интересное решение выводить изоляторы сбоку,а не как обычно- сверху, это при монтаже транс сливать больше половины нужно чтоб их поставить
Да не придётся, там получается как по закону сообщающихся сосудов. Сами вот эти вот адаптеры, где ТТ установлены, примерное на одном уровне с основным баком находятся, поэтому слить масло, будет достаточно примерно что-бы на 1 метр от верхнего края отходило и всё.
