@@Meer_Asif_1 Why worry? You need to measure the tangent phi. And in order not to face the problems of transformer oil, you need to switch to narrower medium voltage transformers.
I used to design transformers like this and the winding assemblies should be dried in an autoclave before being assembled into the housings, and when filling with mineral oil this should be done over a couple of days under vacuum to remove any gasses from the oil and make sure the oil penetrates right into the core of the windings leaving no voids. These transformers risk air pockets in the windings causing arcing when energised. Would be so dangerous being around these when they get put into service.
It's Pakistan a poor country. Compare their manufacturing with that of Indias' and it's rudimentary/stone age. Unfortunate state of affairs in Pakistan.
Damn, this is the worst transformer construction I've ever seen, I can't even believe that they just put those bolt in with a wrench and throw all the torque specifications out the window

It looks like a 20 KV to 380 V oil - cooled transformer. The way they build it will make it fail after one year, instead of the twenty years normally expected by a static machine. We phased out oil cooled transformers twenty years ago in favour of ceramic transformers. The old transformers were a safety hazard, as the oil is highly flammable, and the vapours are explosive. Personally, I prefer properly built oil cooled transformers, as they have a better resistance to transients and peak loads. PS it is the first time I've seen a petrol powered forklift...

Beneath other things, the transformer hast to be evacuated before being filled with oil and the oil has to enter the vessel from the bottom, to enable the remaining air to go to the top.
Super fun to watch them build this, that said not sure I'd classify these guys as "electricians" any more than I'd classify guys stamping out metal parts for a car as "mechanics" unless the terminology is just different over there.

*These are postWWII transformers. They suffer from arcing and electric charge leakage and permeativity capacitance functional issues. About time new models are introduced.*
Yea ok sure. Transformers have not changed much over the years. Yes we have some newer types but In most countries the basic steps of making them which they are doing is still used .
Uma obra de arte, sou Eletricista de Manutenção aqui no Brasil, essa parte de motores, transformadores e geradores, e um trabalho gratificante, e requer amor pela profissão, meus parabéns aos colegas.
Damn... Definitely quite a bit different than ABB... LOL the engineers at Siemens and ABB Hitachi, etc would be appalled.. LOL.. I bet they ship these without any impact recorders too!
They are making cheap transformers, to sell to Pakistani government, with huge profit margins. They don't care about quality but quality. These transformers burst regularly and catch fire. And they get new orders.
In all my 50 years as an industrial electrician never came across an electrician doing boring lower pay boring job of building transformers. Went to the old GE plant on Elmwood Avenue in Philadelphia dozens of times to install & wire in machines. Got friendly with some of the workers. One day after a big layoff they had a janitor applying a dozen rolls of talpe on a high voltage transformer. He asked me if it was okay that he had at least four rolls of tape left over. Told him that when big companies give you a parts box they expect every single part to be used so he throw away the left over tape. Would not want that transformer in my plant. Wish you would show manufacturing from a modern country. Only third world counties use a combination wrench to tighten bolts & nuts. Any modern country started using power tools 60:years ago to secure all nuts & bolts. Besides power tools have the precise torque set to prevent things from coming loose.Gotta love no gloves, no hard hats, no safety toe work boots, no paint booth or approved paint respirator. OSHA would have fined them and closed them down.
It's quite a cultural shock for you seeing for the first time how third world countries struggle to manufacture goods with their own resources? For what you perceive as abomination for them is good enough. It's a developing country, one day they will have enough resources to look for the standards from the "modern countries"
I saw too many shortcuts being taken in the construction. Will they work? Yes, but for how long before something shorts out and causes a failure and possible fire? I am not sure what the end use for the transformers are, but I would not want one near my home!

I am Electrical Engineer and Working in UAE form last 5 years. i am 100 percent sure about that these electricians are not build a transformer even they don't have any idea about a transformer principles, background theories, transformer working and mathematical calculation . because they are not engineers or diploma holder . they are only ordinary labour these are working in a simple workshop at where these transformer are rewinding. but very nice video and i appreciate your work . and keep it up your channel and wish you best of luck for uploading Videos. i am sorry.
Such small transformers at 635 kva to warrant having exposed phase conductors unless they are being connected to overhead cables. If they are to form part of a network it would be better running the cables underground and having a transformer with a Ring Switch/Mains Unit accompanied by an LV fuse board for safety, equipment protection, and for switching/earthing operations. I have no idea why they sprayed zinc galvanising paint over the sight glass on the conservator header tank. The transformer would benefit from a silica gel breather to detect moisture ingress. I also didn't see a tap changer on these transformers either. Some real old equipment right there, would have loved to see the condition of the previous copper winding cores and terminal bushings that came out before the new ones were put in, especially if they had acidic fried oil inside them in previous times. I also wonder what they did with the old oil that was no doubt full of Polychlorinated Biphenyls. These guys did do a good job overall, but they didn't build this transformer, they just replaced the innards of it. They do however lose some points for brazing the contacts.
It's not bravery it's poor workers who are considered as any other merchandise from their company... But I understand your point. It's good work from those guys.
Yeh, watching videos from India, the Middle East, or many Asian countries you don't see a lot of the safety equipment your used to. Though I wonder how the accident rates compare.

Basic error, the output of the conductor of the low-voltage part to the insulating part is not secured even by a washer on both sides. Likewise, the construction nuts have no washers. With the constant vibrations that the transformer generates, I estimate the service life to be a year.
It's not talent. It's skill. U can lean this things in a vocational school or trade school. Talent is God given. Don't tell me wen they were babies they already made this.
The first rocket engines were designed and assembled by Craftsmen too. Hands-on experience is difficult to beat small scale, which is why ramping up the machines that build the machines are proportionately complexity multiplied by complexity. Eg the feel of how tight a bolt is set, is felt by the hand with the nut locking spanner. Tortion spanners aren't necessarily better, except for inexperienced Operators.
I guess they are being careful. That enamel coated wire only has 1KV insulation so the spacers are important. It is interesting. I have never seen laminations like that.
@@micah66048 to his defence he did paint it and there are paints on the market that combine antirust, base coat and finishing coat in one. On the other side you are probably right and this oils can absorb watter and become conductive
@@dadaselectro4794 that was also a very thin coat of paint and with absolute zero proper pretreatment before coating. its better than leaving it uncoated for sure but wont last ten years
Such Transformers had lots of PCB in it. Don't believe this has changed, in best case this will be collected one Day... but even in Europe its hard getting rid of it.
Pcb equipment has not been produced for 35 years and can be properly disposed of by burning at very high temperature to incinerate the dioxin’s completely.
This work is substandard, inconsistent, without many foundational elements of personal protection, and open to many improvements in the process even while maintaining this manual handmade process.
This video is for entertainment purposes. No-one here has the influence to make an actual impact in Pakistan. It’s totally pointless preaching to the choir and in English when these guys speak in Urdu. 😂
specifically here they would not help. The iron core of the transformer alone is well over a ton, if someone's foot ends up between the transformer and the floor, he's loosing to crushing injury, safety shoes or not.
Me too, man. Sometimes I ride by the metal fab down the road and wonder if I should just quit and become a machinist and never have to touch javascript again.

I loved the part where they painted the rusty parts brown. Very professional.
That was red oxide metal primer. They painted entire thing black later on.
@Darrell Dobson Obviously, entire transformer is so cheaply made you expect them to splurge on Rustoleum paint, which is one of the best brands of paints in the world!

“But we have a transformer at home”
Transformer at home:
Lmao this is so accurate. They produced an inefficient bomb and a death trap.
and then they fill it with 15w-40
I never use word Mom and Siemens, not in the same sentence and not in polite company.
Also: why using a mask when spraying paint? My grandpa never wore a mask, why should I?

Beneath other things, the transformer hast to be evacuated before being filled with oil and the oil has to enter the vessel from the bottom, to enable the remaining air to go to the top.
Finally, an impact wrench

Super fun to watch them build this, that said not sure I'd classify these guys as "electricians" any more than I'd classify guys stamping out metal parts for a car as "mechanics" unless the terminology is just different over there.

Это обыкновенный капитальный ремонт трансформатора. Причём провод на высоковольтную катушку использовался вторичный. И не показан процесс испытания транса. Как говорят в России просто колхоз.
Русские самые умные, только кроме русских никто об этом не знает, в этом и есть загадка их души.
В россии ещё хуже делают. Эти хоть любят свою работу, а в рашке на от**бись всё.
"Impressive" uniform insulation on the internal tappings. This is 100% according to IEC60076-3 and would be capable of a full lighting impulse test according to relevant tables. ABB and Siemens have no chance

*These are postWWII transformers. They suffer from arcing and electric charge leakage and permeativity capacitance functional issues. About time new models are introduced.*
Yea ok sure. Transformers have not changed much over the years. Yes we have some newer types but In most countries the basic steps of making them which they are doing is still used .
These transformers burst regularly and catch fire.
Шарашкина конторка. При этом, качество сборки роус ройс. Отличная работа. Уважуха. 👍👍👍

Incredible how lot of manual work goes into this. I've winded small SMPS transformers before and I can't imagine doing big ones like this.

2022 ending, finally embracing last century tech... good job guys!
Damn... Definitely quite a bit different than ABB... LOL the engineers at Siemens and ABB Hitachi, etc would be appalled.. LOL.. I bet they ship these without any impact recorders too!
They are making cheap transformers, to sell to Pakistani government, with huge profit margins.
They don't care about quality but quality. These transformers burst regularly and catch fire.
And they get new orders.
In all my 50 years as an industrial electrician never came across an electrician doing boring lower pay boring job of building transformers. Went to the old GE plant on Elmwood Avenue in Philadelphia dozens of times to install & wire in machines. Got friendly with some of the workers. One day after a big layoff they had a janitor applying a dozen rolls of talpe on a high voltage transformer. He asked me if it was okay that he had at least four rolls of tape left over. Told him that when big companies give you a parts box they expect every single part to be used so he throw away the left over tape. Would not want that transformer in my plant. Wish you would show manufacturing from a modern country. Only third world counties use a combination wrench to tighten bolts & nuts. Any modern country started using power tools 60:years ago to secure all nuts & bolts. Besides power tools have the precise torque set to prevent things from coming loose.Gotta love no gloves, no hard hats, no safety toe work boots, no paint booth or approved paint respirator. OSHA would have fined them and closed them down.
It's quite a cultural shock for you seeing for the first time how third world countries struggle to manufacture goods with their own resources? For what you perceive as abomination for them is good enough. It's a developing country, one day they will have enough resources to look for the standards from the "modern countries"
I saw too many shortcuts being taken in the construction.
Will they work? Yes, but for how long before something shorts out and causes a failure and possible fire?
I am not sure what the end use for the transformers are, but I would not want one near my home!
it's oil submersed, construction is the same as original, its repair old one.
Said like a true privileged righteous white american.
@@jirkas229 and the old one failed and burned out because.... ? Care to take a guess?😂
It's designed to burn out so they can repair it, how else is the business going to ensure repeat business! 😀

Rebobinamento de trafos. Ótimo trabalho. Eu adoro transformadores. Isso me fez fazer curso de engenharia elétrica, porém, eu nunca trabalhei com isso!
Eu também amo essa parte de equipamentos. Sou engenheiro eletricista também e já trabalhei com trafos e é muito satisfatório ver um trabalho bem feito assim
Isso apareceu na minha timeline agora não consigo mais parar de ver esses videos, é muito interessante e dahora ver como é feito os transformadores e eu que sou um cara que ama eletronica e essas coisas de engenharia então so me faz ficar mais fascinado por essa area.
I am Electrical Engineer and Working in UAE form last 5 years. i am 100 percent sure about that these electricians are not build a transformer even they don't have any idea about a transformer principles, background theories, transformer working and mathematical calculation . because they are not engineers or diploma holder . they are only ordinary labour these are working in a simple workshop at where these transformer are rewinding. but very nice video and i appreciate your work . and keep it up your channel and wish you best of luck for uploading Videos. i am sorry.
It is very respectable to do the work you like and persist for such a long time.
Such small transformers at 635 kva to warrant having exposed phase conductors unless they are being connected to overhead cables. If they are to form part of a network it would be better running the cables underground and having a transformer with a Ring Switch/Mains Unit accompanied by an LV fuse board for safety, equipment protection, and for switching/earthing operations. I have no idea why they sprayed zinc galvanising paint over the sight glass on the conservator header tank. The transformer would benefit from a silica gel breather to detect moisture ingress. I also didn't see a tap changer on these transformers either. Some real old equipment right there, would have loved to see the condition of the previous copper winding cores and terminal bushings that came out before the new ones were put in, especially if they had acidic fried oil inside them in previous times. I also wonder what they did with the old oil that was no doubt full of Polychlorinated Biphenyls. These guys did do a good job overall, but they didn't build this transformer, they just replaced the innards of it. They do however lose some points for brazing the contacts.
cool, so I know the processing of electric transformers, thank you my brother, always success
You are welcome.
I’m amazed and the talent to pull this off and the bravery to not wear steel toe safety boots.
please change the word "amazed" to "appalled" because you care about safety and well being of a fellow human!
It's not bravery it's poor workers who are considered as any other merchandise from their company...
But I understand your point. It's good work from those guys.
Very Repetitive Job! after building 10 it's the same old same from design book for that country.
No hearing protection for the guy with the pneumatic impact wrench.
No respiratory protection for the spray painter.
A CEO's wet dream.
Yeh, watching videos from India, the Middle East, or many Asian countries you don't see a lot of the safety equipment your used to. Though I wonder how the accident rates compare.
very nice safety measures very good!👌
Glad you like them!
The flip flops or the lack of masks when doing any work that requires a mask?

Princeble same HV-MV-LV. You can see every part of transformer without OLTC and Condense Bushing. Thank you for producing this video.
You are welcome!
Basic error, the output of the conductor of the low-voltage part to the insulating part is not secured even by a washer on both sides. Likewise, the construction nuts have no washers. With the constant vibrations that the transformer generates, I estimate the service life to be a year.
ok genius
@@jisooturtlerabbitkim3734 ok genius, it's about the transformer lasting 10 years, not 1 year.
Sad. Washers are so useful, but I see them so rarely used. Everyone just puts on a nut and walks off, but a washer just takes a second!
@@LightTim And I think writing about anti-slip toothed pads is useless.
If that
It's not talent. It's skill. U can lean this things in a vocational school or trade school. Talent is God given. Don't tell me wen they were babies they already made this.
The first rocket engines were designed and assembled by Craftsmen too. Hands-on experience is difficult to beat small scale, which is why ramping up the machines that build the machines are proportionately complexity multiplied by complexity. Eg the feel of how tight a bolt is set, is felt by the hand with the nut locking spanner. Tortion spanners aren't necessarily better, except for inexperienced Operators.

I guess they are being careful. That enamel coated wire only has 1KV insulation so the spacers are important. It is interesting. I have never seen laminations like that.

Being pedantic, transformer aren't rated in watts
Such Transformers had lots of PCB in it. Don't believe this has changed, in best case this will be collected one Day... but even in Europe its hard getting rid of it.
Pcb equipment has not been produced for 35 years and can be properly disposed of by burning at very high temperature to incinerate the dioxin’s completely.
This work is substandard, inconsistent, without many foundational elements of personal protection, and open to many improvements in the process even while maintaining this manual handmade process.
And your point is?
That may be true in developed countries, but not in developing.

It would be miracle to see any worker in safety shoes. They all are having the healthy foots
specifically here they would not help. The iron core of the transformer alone is well over a ton, if someone's foot ends up between the transformer and the floor, he's loosing to crushing injury, safety shoes or not.
