The West, after the request of the Ministry of Energy of Ukraine, promised to supply high-voltage equipment

Today it became known about the appeal of the Ministry of Energy of Ukraine to Western countries regarding the supply of high-voltage equipment. Energy Minister Herman Galushchenko personally called up his EU and US counterparts, European Commissioner for Energy Kadri Simson and officials from the leadership of the US Department of Energy, respectively.

We have already received equipment and materials from our Western partners, for which we are very grateful to them, but in addition to this, we will also need high-voltage equipment to restore the energy system

- the minister said.

According to the Ukrainian ministry, the EU and the US have promised to provide all necessary assistance to support Ukraine's energy sector. At the same time, it is not reported when such deliveries will be made and in what volumes.

It should be noted that any requests for the supply of such equipment without Russia's participation in these negotiations lose all meaning, since, one way or another, it will again be subjected to missile attacks from Russia in the absence of a constructive position from Kyiv and the West itself. What's more, it can take months to install, essentially putting supply efficiency into question.

Recall that the energy system of the Kyiv regime continues to be hit by Russian high-precision weapons since October 10, which was a harsh response to the terrorist attack on the Crimean bridge, arranged by the Ukrainian special services. To date, the degree of destruction of objects
energy infrastructure of the territories controlled by the Kyiv regime is at least 50%. The Ukrainian authorities are hatching plans to switch the entire energy supply system to the European grid. But, again, how much time and money it will take.

And will they also transfer all energy to other standards?

[private person]

And will they also transfer all energy to other standards?

Well, if you believe our officials, there is nothing to translate there, but you need to rebuild for a new one.

[topol717]

What other standards???
what are you talking about? throughout Europe the same 230 volts and 50 hertz.
so the standards are still the same.

[KCA]

Does Russia destroy sockets in houses? Don't you realize the difference between the consumer and the transmission of electricity? Step-up and step-down equipment is being destroyed, and here is an ambush, high-voltage equipment standards:

In Russia, two series of nominal voltages have been developed, which include both ultra-high and ultra-high voltage lines. The first scale is 110-150-330-750 kV, the second is 110-220-500-1150 kV.

U.S.:
The first scale includes voltages of 138-345-765 kV and is used in the Southwest, Center and North of the country, the second - voltages of 115-230-500 kV and is used mainly in the West and Southeast of the United States. The role of intersystem connections and backbone lines is performed by lines 345-765 kV. Work is underway to create equipment for 1600 kV transmission lines.

In general, you can list all countries, ANYWHERE high-voltage equipment does not come close in terms of the voltages used, you will have to change the ENTIRE power system of the outskirts, these are trillions of dollars

[Rzzz]

Voltage is not a problem at all, transformer substations are being installed, and that's all.
It is more difficult to synchronize networks, yes. But it is also a problem to be solved.

[KCA]

Exactly what to put? I wrote the standard voltages of the transformers of the outskirts (the former Ukrainian SSR) and the USA, how to cross a snake with a hedgehog, if at one end of the power line the transformer increases to 138kV, and at the other it reduces from 110kV? Can you tell me what I don't understand? Transformers to our standards were made only in Ukraine, but it no longer does anything, and Russia, but it won’t supply shit to / from, and what’s the way out?

[Rzzz]

What about US standards? Electricity will be supplied from neighboring Europe, and there the standards are exactly the same.

[KCA]

What article are you commenting on?
"Today it became known about the appeal of the Ministry of Energy of Ukraine to Western countries regarding the supply of high-voltage equipment," where is the supply of electricity?

[Rzzz]

The largest manufacturers of power equipment - Siemens, Schneider, ABB, and others - are, as it were, European. Yes, and American manufacturers are also able to produce European standard equipment.

[KCA]

If they have never produced high-voltage equipment, especially oil-cooled transformers, for voltages and USSR standards, do you think that in one day they will change the design documentation and stamp everything? These are years, one 330kV transformer, say, is made only to order, in warehouse storage, if any, then 1-2 (in Russia), and production from 8 months to a year, and more, then the cargo is oversized, it is required special transport and special logistics, most likely delivery by sea, if from Germany, and in the Black Sea mines sometimes float

[Rzzz]

Not so many years, everything is being done faster. Large things, I expect, months, little things, and so there are in warehouses. These are large manufacturers, they do these things not piece by piece, but quite massively.
And modern equipment is quite compact, much smaller than what was in Soviet times. And this means that it is easier to carry it, and takes up less space.

[KCA]

It is impossible to reduce the dimensions of the transformer, you cannot deceive physics, the size of the core, the number of turns of the windings and the cross section of the wires cannot be changed, some reduction can be achieved by installing cooling with forced circulation of the refrigerant and ventilation. It is possible that Russian and Ukrainian factories are very outdated and therefore their production time was about a year, but for them these were serial products, the Germans will have to do from scratch, and even in conditions of shortage and high cost of electricity

[Rzzz]

Quote: KCA

It is impossible to reduce the dimensions of the transformer, you cannot deceive physics

A substation is more than just transformers. It's a bunch of other equipment. Which has just become more compact.
And instead of one huge transformer, you can put several smaller ones in parallel.
As an example, I used to have a rather large open substation not far from my house. Now it is gone, it has turned into a building of a rather small size, and the site where poles, transformers, switches, and other high-voltage crap used to stand is now cleaned up, and a residential building is being built there.

Do you really think that for a 750 kV route (existing in Ukraine) it is possible to use a 765 kV cable (used in the USA) to connect interconnections?
Everything will have to be shifted and this is not a year, I think it will really be 5-6 years. And this is subject to sufficient investment

[Sergio_7]

Well, why not do it like in the states, the mains voltage is 110 V!))

[Arkady007]

Everything can be done, but who will redo the wiring in homes and enterprises according to other standards and technologies?

[Bumblebee_3]

Arkady007 (Arkady)
Yes, wiring in houses is always done with a large margin. Nothing needs to be changed.

[Bumblebee_3]

Sergio_7 (Sergey)
Well, why don't you like the voltage of 110 volts? The wires need a little thicker, so what? I also think, like Aaron, they will do their best.

[Illanatol]

Will household appliances designed for 220 V work?
By the way, the Yankees also have a different AC frequency: 60 Hz, not 50, like ours.

[Andy_nsk]

Well, why not do it like in the states, the mains voltage is 110V

I think this makes no sense, since step-down transformers for 220V are either in the yards or right in the houses, there are a lot of them and you can’t stock up on them with calibers. High-voltage transformers at substations are being destroyed. Here there are few of them and the non-brothers are tormented to change them, until they bring and install them - weeks or even months will pass. The energy system will be destroyed much faster, hopes that we will not have enough missiles and UAVs seem to be futile, they have learned to produce them in large batches, the military-industrial complex works without rest!

[solar]

it's a delusion. In the States, household voltage is 220 volts (110 + 110)

[Rzzz]

And what about the states. They are on the other side of the planet.
Europe has 230 volts.

[solar]

In Europe, the standards are practically the same. In the United States, in many cases, there are also no differences at the level of high-voltage networks. Differences in household wiring and frequency.

[Brturin]

Quote from solar

there are also no differences at the level of high-voltage networks

the question remains where the network frequency is set ... by generators of power plants, then there is still a difference ... for their frequency, their transformers for optimal operation

[tralflot1832]

Let them take American transformers for American El networks. They are reliable as a dollar.

[dmi.pris1]

In the eighties, he worked at one tricky production in Smolensk. There, at one PTS, there was an Amerz power transformer to our standards. It’s clear what they will do, only this will take time

[tralflot1832]

I'm kidding about the frequency of the current! In America, it is somewhat different.

What's there to poke fun at? The electric motor rotates a little faster. On an incandescent light bulb, this does not affect it in any way.

[seamen2]

Do the electronics also *spin a little faster*?

[Bumblebee_3]

seamen2 (vasily)
EMNIP electronics works on direct current! And that's what power supplies are for. No difference 220x50 or 110x60. There is both. In Japan, too, 110x60. Also tell me that they have electronics to hell.

[seamen2]

of course have. I’ll just tell you this is for every Ukrainian washing machine and so on, such a block is needed. rupee-five where to get? will the Japanese send?

[Bumblebee_3]

Quote from seamen2

I did not understand you. in fact, it was not about the fact that you need to change power supplies or something else. Leave that to those who want to bring equipment from the US.

[Rzzz]

In electronics, there are always power supplies at the input. Mostly impulsive.
At the beginning of the circuit of any impulse device, there is always a rectifier, further conversions are made "from direct current".
Therefore, there fuck, how many hertz at the input. The only caveat is to correctly design the input noise suppression circuit.

[Brturin]

Quote: Bumblebee_3

The electric motor rotates a little faster.

Why would .. then you need to change the generators at the stations (nuclear power plants, hydroelectric power plants, thermal power plants), and these are such costs, so that the generators remained 50 Hz. and include 60 Hz transformers in this network ... (transformer frequencies do not change) ... let them try ... before they preferred the order specifically for hertz

[Bumblebee_3]

Quote: BrTurin

Why would

Should I give you a lecture on electrical engineering? The frequency (speed) of rotation of the electric motor DEPENDS on the frequency of the supply voltage! The transformer doesn't care! What received at the input - the same will be transmitted at the output. Just don't talk about pulse transformers and their varieties now

[Brturin]

Quote: Bumblebee_3

The transformer doesn't care! What received at the input - the same will be transmitted at the output.

I repeat again -

then you need to change the generators at the stations (NPP, HPP, TPP)

if you agree that the transformers do not change the frequency, then why should it change in the Ukrainian network (for the same motors) if the generation is the same ... and what is the "lecture on electrical engineering" about how they will work in high-voltage 50 Hz. networks, 60 Hz. transformers

[solar]

The whole problem is contrived. Factories in the States produce transformers for sale worldwide, not just for the domestic market. There are a large number of standard solutions.

[Brturin]

in principle, yes ... and the Japanese are also made by the same Europeans, only piece goods (on order, they are not in warehouses) and not cheap (especially in modern times), and overall ... the issue is payment and time (and For winter, this is not the last factor)) ...

[solar]

Depends on what. The voltages in the networks are standardized, and standard products are produced for them in serial order. Either very high power transformers or non-standard ones are unique. Here they are, on order.

[Andy_nsk]

The frequency (speed) of rotation of the electric motor DEPENDS on the frequency of the supply voltage! The transformer doesn't care! What received at the input - the same will be transmitted at the output.

That's right, just don't forget that a 50 Hz transformer has 60% more turns than a 20 Hz transformer.

[dmi.pris1]

There, not only the frequency, but also the voltages are different than in Europe. Yes, and we do too. In the States, in general, the approach to organizing networks is different

[Bumblebee_3]

High-voltage equipment is always a "piece" product. Serially few people produce. These are not bolts with nuts that are "stamped" by the millions. And it doesn't take long to make. They have work

[solar]

not always. there are standard ones that are mass-produced

[Bumblebee_3]

Quote from solar

The key here is "not always". Model ones do release, I agree with you

[Rzzz]

In Russia, half of the high-voltage equipment is Siemens and ABB. What prevents the same equipment from being delivered to Ukraine? Moreover, the Russian market for these manufacturers has now "fallen off"?

[Mountain shooter]

Quote: Bumblebee_3

The production cycle is three months. If there is no production queue. And there is a blank of iron for the cores ...

[Illanatol]

The production of transformers is not necessarily as high a priority as the production of weapons.
Many have heard about the weapons lobby, but about the transformer ...
And it may turn out that all these transformers and the like are produced in China. There will be laughter.

In a household network, you can do 110. But the speech is high-voltage.
I never thought that the power transmission lines in our country and in Europe are different.
I knew about the width of the "piece of iron" from school. And I didn’t know about this, about different power lines. (
Here is another big plus for reading news and comments on VO. You learn something you didn't even know.

[solar]

I never thought that the power transmission lines in our country and in Europe are different.

they are not different. Yes, there are different networks there, but a lot of them are the same as they were in the Union.

[Arkady007]

Everything can be done.
But everything needs money and time and people who will do it.
Who will retrain Ukrainian electricians for other technologies and how long will it take?
And what to do with TVs, refrigerators, etc., which are tuned for a different voltage and frequency?

[solar]

the electronics are powered by direct current.
Yes, and calibers do not fly into the refrigerator. These are high voltage equipment.

[Andy_nsk]

Who will retrain Ukrainian electricians for other technologies and how long will it take?

Not much

And what to do with TVs, refrigerators, etc., which are tuned for a different voltage and frequency?

Are you able to read? It is supposed to replace high-voltage equipment, no one is going to change our favorite 220V 50Hz.

[Arkady007]

Here is an excerpt from a clever article.
Due to the fact that the voltage is 2 times higher, the consumed load can be increased by 4 times with the same length of the network. Since a three-phase system allows 2 times the distribution network length compared to a single-phase system, it turns out that in Europe it is possible to lay distribution networks 8 times longer than in America, while meeting the requirements for overload and voltage drop.
Now imagine how many alterations and additions must be made along all the power lines.

[Andy_nsk]

How does this article relate to the need to replace high voltage transformers? These voltage transformers are hundreds of kilovolts, not 110 or 220 V.

[Tagan]

The Ukrainian authorities are hatching plans to switch the entire energy supply system to the European grid.
I wonder what plans the authorities of European countries are hatching in this case, especially when a monster in the form of Ukraine hangs (switches) around their necks? Where do they switch to?

[Bingo]

promised to supply high-voltage equipment

Do I understand correctly that an aluminum crap stuck between the lower hemispheres of the khokhlomozb, at the time of the arrival of the bouquets, will provide electricity to the whole of Europe?

[seamen2]

*Note that any requests for the supply of such equipment without Russia's participation in these negotiations lose all meaning*.
Yes, our negotiators are * of the wrong system *. almost Kozyrev system. not Gromykovskaya. so there is no need for negotiation. it will be even better.

You were probably present during the conversation and a specialist in high-voltage equipment, based on these facts, issue a decision? High-voltage equipment - transformers, switches, control systems for them - do not lie on the shelves and you first need documentation / specification, then design, then to the factory, where there is a queue for manufacturing, manufacturing itself, acceptance, delivery, installation, connection, acceptance. A sane person, knowing that in the end it would come under fire again, could hardly say such a thing. You probably come from Ukraine, they love the motto so much - the West will help us

[solar]

High-voltage equipment - transformers, switches, control systems for them - do not lie on the shelves

Depends on what. For example, equipment for mass networks of 110 kV is mass-produced in a fairly large number.

Of course you can ask, but what will you pay!? There are the same Jews and they will not give anything for free !!! that is, a proven scheme - a loan from the EU with interest, goods under it.
