I'm not an electricity power engineer, but it looks like each low voltage phase (secondaries) consists of 2 windings in parallel. I guess this is simply because a single winding would be to stiff to wind on by hand. The high voltage primaries looks also to have 2 windings each as well, one with taps, the other without. In operation at the lightest loads, the transformer primary would have just the phase windings without taps connected to the incoming supply. As an automatic 'on load tap changer' detects secondary voltage drop with increasing load , tapped windings are switched in parallel to restore the secondary voltage, i.e. automatic tap changing takes place without interruption to the supply.
As an electrical engineer, I assure you that you cannot connect windings with different numbers of turns in parallel on one core. Such a connection generates equalizing currents that increase power losses in the transformer.
@@zenonbiusz Well, surely we can assume these guys know from experience what works ok and that there primary objective here is good voltage regulation. We're not all theorists and there practical solution is two equal parallel windings, but one supporting the other from one of five end taps. With a tap selected that's a potential 1/5 of full full load current mismatch. So that's just a tolerable 1/25 extra as a winding power loss, but importantly no extra winding loss when the transformer is working flat out on full load.
@@robertlong2531 I looked this video again. It's different from what you wrote. The transformer has a Dy winding arrangement, meaning the high-voltage windings are connected in a delta, and the low-voltage windings in a star. The entire winding of each high-voltage coil is connected in series, and the taps are located halfway up the coil. That's where the tap is selected, which connects to the beginning of the second half of the winding.
@@user-bj4lp3fr1o Split lock washers don't help against losing torque, but they do help against fully undoing the bolted connection, so in my opinion in this case it would be helpful.

Whilst these are rather small transformers, the construction requirements are generally similar throughout all scales. Look how much time and effort goes into just the one; now, consider how much materials / time / effort goes into the very HV "Supergrid" systems, and consider the far, FAR longer lead times for replacement should they be significantly damaged, as we saw in the US Metcalfe attack in 2014 ($15 million in damage over 20 minutes).
our military budget costs us 1.5 million a minute, 93 million a hour or 2.2 billion a day. so while 15 million in 20 minutes sounds like a lot, when compared to real wastes of money...it's not even a drop in a bucket. clearly the time and effort required to build these transforms is no joke, still the cost of that attack isn't much in the grand scheme of things. also seems kinda crazy that they wouldn't have replacements ready....but i suppose that shouldn't be unexpected with how lax regulations are for companies.
@@rocksfire4390 Its the time requirement and limited amount of manufacturers. Lead times are insane right now. Almost 2 years for any transformer order if you can even get a manufacturer that will take an order.

Interesting that they don't do any measurements during the assembly, when any errors would be relatively easy to fix. They only measure when the transformer is already assembled and filled with oil, when any issue is most difficult to fix.

This is likely not General Electric or ABB. I don't see too many production workers in factories I have been to in the United States wearing flip-flops.
At 4:43 I was a little concerned that the torch carbonized the cloth on the adjacent cables. Is it possible that arcing could occur at that point causing failure of the entire transformer?
0:47 It's amazing how thick the wires are. They're actually more like copper bars. There must be a lot of current going through those! 6:23 They really have to hold it together with some heavy-duty hardware, since the magnetic force when it's running must want to sproing the whole thing apart like a slinky toy.
They did not provide any information, but for India this is most likely 11kV to 400V. If that is the case, 131A primary and 3612A secondary. It is a delta wye unit, so the primary winding current would be 76A.
I'm no expert but if that transformer is for step down then shouldn't the high voltage winding, which would be the primary, be fitted nearest to the core? Or is that too high a risk of insulation break down?
La Corriente Alterna sigue siendo un mundo misterioso para mí y los entresijos técnicos los desconozco; llevo unos cuantos meses viendo procesos "industriales" en Pakistán y de unas semanas a acá, no puedo dejar de alegrarme porque cada vez los talleres que veo son mas limpios y las condiciones de los trabajadores parece que mejoran.

Ojalá que no les falte trabajo ni dejen de mejorar.
at 10:25 the spray painted label says that the transformer capacity is only 400KVA and not 2500KVA. Also the coil windings are not scientific. There should be more space near the edges.
no that is another transformer sitting behind this one. the 400kva is in blue . there is nothing in blue on this one. it's also way too big for only 400kva.

Danke. Das ist der Kommentar, nach dem ich gesucht habe. Auch als Nicht-Elektrotechniker scheint mir an einigen Stellen die Qualität nicht wirklich gut...
The complete transformer may handle kilovolts but the potential difference between the individual windings is so low it can be insulated by only a coat of varnish and some very thin cloth.

I have watched 20..30 similar videos, I find it amazing that these people produce complex products with such simple tools. But now, for the first time, I have to say that using a hammer handle is just stupid. A wooden or plastic hammer costs a few cents. But a simple piece of wood would also do, as we will see later.
Can we please send these people some damn work boots? One guy has an orange vest and hard hat, next guy is wearing sandals. How can anyone be competitive with companies that have Zero environmental, health and safety standards?
From what I can see the primary is 3 phase 3 wire delta. The secondary is 3 phase 4 wire Y. In my area the primary voltage would be 34,400 volts and the secondary would be 277/480 Y with a grounded neutral 60 hertz. I dont know what nation you are from but what would the primary and secondary voltages be on this transformer you show in the video?? Hear in the states we have what they call a pad mounted transformer thats 2,500 kva thats dead front that sits on the ground and you dont need a fence or vault to put it in. It sits next to the building its serving.

중국이라면 알루미늄+거짓용량으로 소비자를 속일것입니다.
@@gomdolri 그것은 모두 기술 제어 부서에 달려 있으며 고품질이 있고 가짜도 있습니다
@@AnotherPointOfView944 aluminum does actually find use in large distribution transformers (it's good for foil windings and especially for resin cast unit), but copper definitely is a better conductor. Oil soaked paper (or cardboard as you put it) is the norm for transformer insulation, and isn't a "low quality Chinese" thing
hätte ich an der Abschlussprüfung als Elektrowickler so gearbeitet ich wäre durchgefallen. die arbeiten wirklich wie im Urwald. Sauberkeit ist hier ein Fremdwort, Lötstellen sauber Verputzen ist kein Thema für diese Leute. angebrannte Isolationen an den Spulen und vieles mehr.
Danke. Das ist der Kommentar, nach dem ich gesucht habe. Auch als Nicht-Elektrotechniker scheint mir an einigen Stellen die Qualität nicht wirklich gut...
Não importa qual é o seu trabalho, faça-o como se dele dependesse o mundo. 🇧🇷👍🏼🌿
Num certo sentido é vdd msmo...
Если ещё пропитать специальным лаком и в печь поставить , то ещё в два раза гарантия качества...😊
What is the purpose of those wrapping materials? Are they used to insulate this much heavy conducting material? Just curious to know.🙏🏽
Yes.
The complete transformer may handle kilovolts but the potential difference between the individual windings is so low it can be insulated by only a coat of varnish and some very thin cloth.
@@andrewallen9993 2500 KVA = 2.5 million VA.
@@AnotherPointOfView944 Amps heat wires, volts eat insulation. Thick copper, thin film of varnish and cotton cloth :)

Bravissimi tutti i miei complimenti 👍
No way I’d energise that on the grid
байден норм ?????
It's a 12 volt to 5 volt transformer, correct?
OK, my last offer, 14 volts
Oh but you do & much worse, without realising it. Lets just say I know I work in industry. Ahem..
This will blast into pieces immediately
É muito triste ver vcs fazerem um trabalho tão maravilhoso, mas sem nenhuma proteção de ipi.

Самый главный вопрос....... Где они столько меди взяли! )))
SARCAM firmasından almışlardır.
it's made in Pakistan 🇵🇰
Кастрюли переплавили .
Stole it from the street lamps in my neighborhood 😡
@@muzikizfunno they didn't. 😡
Beautiful job ! Lots of hard work !
No se puede creer que existan personas que trabajen en condiciones sumamente precarias sin elementos de seguridad ni protección . La avaricia del ser humano y la explotación de sus semejantes
I like how they make things.great job guys.
был очень удивлен производством однозначно лайк
Это вам не лапти для негров плести !
6:38 all that and the wrench they use doesn't fit?
Кругом медь! Нифига себе
Great video, thanks for sharing your expertise.
Thanks for watching!
Uau, que procedimento bacana da construção de um transformador.
Semangat...sukses selalu salam dari indonesia
Thanks for the tutorial, it's much faster than any other method I came across.
6:38 Впервые в жизни увидел ключ на 25. For the first time in my life I saw a key for 25.
У меня есть ключ 52 на 54
I am not working in this business but I can assure that this is not the regular way how these transformers are manufactured.
Pretty nice,thank you soooo much
I feel so happy when I see Muslims people can do that. Big salutations from Tunisia 🇹🇳.
Brother this is made in remote area somewhere in Pakistan, i am working in trafo industry with a professional environment and more quality assurance. But these guys are working locally with limited resources should be appreciated 👍
@@aadisiahposh
That's great, so you're working in the same field as me. In the current date, the Pakistan is considered as one of the most important country in the electrical engineering in world wide.
I love so much the Pakistanien people and I do hope to visit you soon. Spelling God.
@@YahiaSaoudi can u provide any link to support your claim regarding " Pakistan is considered as one of the most important country in the electrical engineering in world wide"
@@sagaronline265
The level of transportation voltage there is exceeding 1250kV however in USA is about 1150kV.
@@YahiaSaoudi ok,one reason for that is us operates on 120 v supply voltage.. so they might not need 1250 kv.
even than how this point makes pakistan most importnt in world in electrical engg.
Super videos ! 👍
Ok..so who's doing the quality control...geez
There's QA?
Es maravilloso la fabricacion de Transformadores gracias por compartir
The complete and total disregard for worker safety is astounding.
It’s a third world country.
I have watched 20..30 similar videos, I find it amazing that these people produce complex products with such simple tools. But now, for the first time, I have to say that using a hammer handle is just stupid. A wooden or plastic hammer costs a few cents. But a simple piece of wood would also do, as we will see later.
А по факту импортозамещение!)
Can we please send these people some damn work boots? One guy has an orange vest and hard hat, next guy is wearing sandals.
How can anyone be competitive with companies that have Zero environmental, health and safety standards?
the power switch at 9.45 looks a real bodge job
У меня есть некоторая хотелочка щобь Билгейтс и Илонмаск посмотрели етот видеосик ...
Успехов Вам, мужики !!! ...
Torque wrenches? Torque wrenches? We don't need no steenking torque wrenches!
Transformer production facilities are the perfect place for flip flops. I always say
No, No. Those are safety flip-flops!
From what I can see the primary is 3 phase 3 wire delta. The secondary is 3 phase 4 wire Y. In my area the primary voltage would be 34,400 volts and the secondary would be 277/480 Y with a grounded neutral 60 hertz. I dont know what nation you are from but what would the primary and secondary voltages be on this transformer you show in the video?? Hear in the states we
have what they call a pad mounted transformer thats 2,500 kva thats dead front that sits on the ground and you dont need a fence or vault to put it in. It sits next to the building its serving.
