This is 25 kva transformer I m transformer company owner and self worker in india

It looks like 50 or 75 kva although

they are tallented but not professionals. it is more like a diy low cost power transformer

the advantage of working near the gound is, nothing can fall down and gets probably destroyed (porcelain isolators for instance) 😅

good chance of it.

Well this is a huge problem ... and alot of countries take advantage of these less wealthy countries to do their dirty work ... one example is lithium mines ... the ore is mined by people making pennies a day often children ... sent to China for processing ... then bought as the final product .. thay way thi gs like carbon tax . Green house emissions , pollution don't matter

@@dunk5647 that is a very old transformer so it looks like it would only be used by the locals.

yes, there is a very good chance that is high PCB oil and they keep getting it on their hands. i work with transformers in the states. these guys need proper gloves but we all know they don't have them and even if they were given gloves they would not use them as they are used to doing things their own way.

they have limited resources, that's why they fix and forge some things. I saw another video from India, don't remember what they were fixing but in the end they putted the same old oil. I think it was a truck suspension.

Your knowledge very good

25kVA ;) just a little transformer… really bad work…

Well said. They did boil the oil, but that's not enough. The oil should be tested, you have to determine it's breakdown voltage. Oil samples should be taken regularly from transformers and tested.

Yes, 63 kVA, the primary current is 2,7 A. at 13,8 kv that is making sense for the wiring used. Otherwise, 635kVA the current would be 27 Amps.

😂

Yeah I liked the tie a knot in the hoist chain part.

Да это одно из самых не вредных масел, его пить можно оно чистейшее, особенно хорошее когда горячее прям как чай. Сто раз так делал.

if the oil is still full of pcbs they will have alot of health issues

Looks like it came back for warranty work! 1:30 "Warranty Valid Upto 02:2024"

Круговорот

судя по тем помоям ,да ещё и такой температуры!!! которые они туда залили- если при старте не ёбнет-то дня 2-3! "может" и проживёт,но это не точно.

Это высокая сторона тр-ра. Там ампераж минимальный.

Интересно сколько КПД? Это трансформатор - хулиган !

They are doing it in Lahore Pakistan. PEL written on transformer is engineering company Pak Electron Limited Lahore Pakistan

Αυτός δέν γνωρίζει τίποτε από αυτά τά υλικά!!! Μέ γυμνά χέρια... αυτά είναι όλα επικίνδυνα υγρά....

Here in Germany some People glue their Hands on the Street because the are afraid of Climate Change 😅 in India they cook old Insulation Oil on open fire 😂

1:20 Where he puts the nuts after unscrewing them, that's a spark gap. And that's about the absolut most kind of "protection" there will ever be Also cooking the coils in oil will absolutely destroy the insulation of the enameled copper wire

There is no need for testing as some equipment to ensure the functioning of the transformer is pre-made, that is, from another of the same power.

Because of bad design and not so good material used....the efficiency should be quite low, also imposible 635 KVA, the transformer pretty small, should be only around 30 KVA

@@agustonogandasaputra7862 It says 25kVA on the winding assemblies at 2:43. They also don't do proper vacuum impregnation or core bake outs, so air void corona discharge and residual moisture can also kill them early.

Yes, and probably they will live -70 years because PCB is toxic when in contact with humans

Definitely does judging by how old the transformer is and the color of the oil maybe.

Это чтобы синкопа в пиццикато в басах не запаздывала😄👍

​@@egor988atr На последнем ладу.

Проволоки небыло нужного диаметра, растянули немного, чтобы войти в параметры

220 V

The EPA would shit their pants if they saw you boiling oil in a barrel. We do this sort of work and the machine used to do that same thing looks like a minivan-sized oil refinery on a skid 😂

@samiamm5764 lol I get that part about the EPA...I meant repair and reuse part

they are

Probably 25kVA lol

С какого перепугу оно становится радиоактивное? Как вы такие бол _ваны естественный отбор обманываете?😂

This video is from pakistan not from india

Yes. This could cause accidents, such as power outages and transformer malfunction

Статья в Вики "Трансформаторное масло" подробно объясняет это

Влагу убрать из масла и из трансформатора

@@HARDChannel чётко и ясно! Сам не допёр просто. Думал что если налить горячее масло и сразу заболтить крышку герметично, то после остывания масла образуется вакуум и это минимизирует окисление и насыщение масла влагой.

@@MakLauD_2La масло - диэлектрик. Транс на несколько киловольт. Свойства масла напрямую зависят от влаги в нем. Но эти как обычно, нет чтоб новое залить, льют отработку кипяченную

@@HARDChannel при таком же раскладе можно было готовую обмотку поставить, а не наматывать новую. Можно было вообще не ремонтировать это всё, а новый или с ремонта поставить потребителю. Вообще, с технической точки зрения, не вижу ничего криминального прокипятить это масло, тем самым выпарив из него влагу. Оно как было диэлектриком, таким и осталось. Ну да, в этом всём виднеется лютый колхоз просто. Но люди работают.

2:41 The transformer has 25 KVA. It even says so. The guys certainly can't read.

легко, только кран нужен. это цыгане. всё у них просто, главный инструмент в ремонте это тряпка.

go and do it yourself then

go to pakistan and show them how its done

You can’t even write properly so I doubt you have done anything “I work transformer” licence work before.
