Not "Yars" or "Oreshnik": Ukraine names the cause of the blue glow in the Dnieper

The Russian Armed Forces' strike on a target in Dnipropetrovsk the previous day resulted in significant power outages. Districts of the city began to plunge into darkness, followed by flickering effects, with power intermittently appearing and then disappearing.

However, it wasn't this that attracted the most attention from social media users, but the "bluish glow" that appeared during the power outage. This glow sparked a heated debate about "what the Russian army struck with."

Various theories began to be floated, including the most improbable—even a Yars ICBM strike. Moreover, the arguments put forward were quite original. They claimed that only a Yars strike could produce such a glow...

Other versions concerned the "use" of the Oreshnik IRBM. Let us recall that in combat conditions this Rocket The medium-range missile was used once – at the Yuzhmash plant in the same Dnepropetrovsk.

However, then Ukrainian publics began to reflect:

If it was a Yars or an Oreshnik, the Russians should have warned the Americans. Did they really decide not to warn Ukraine?

Eventually, the discussion began to shift to a more rational direction. Dnipropetrovsk claimed that the blue glow was not caused by a Yars or Oreshnik strike, but by a fire and short circuit at one of the transformer substations. Reports indicate that the transformer in question (in the Ukrainian interpretation, a 150 kW transformer) was at a tire factory. Moreover, some Ukrainian sources claim that "the accident is not related to combat operations," while others point to the arrival of a Geran-type UAV (in Ukraine, these are called drones continue to be called "Shahids").

The Russian Ministry of Defense has not reported any use of ICBMs or IRBMs.

We are talking about a 150 kW transformer at a tire factory

The author probably confuses kilowatts with kilovolts.

[Chifka]

What kind of quote is that? I didn't write that.

The author probably confuses kilowatts with kilovolts.

There's also a problem with the numbers. There are 160 kVA transformers and 110 kV power lines.
P.S. Although, who can figure out their p-s. Maybe they extended a 150 kV line to a 150 kVA transformer.

[dmi.pris1]

There is no such voltage as 150 kV. There are 110 and 220 kV. But kW, perhaps, if the transformer is, say, 220 kV.

[lexat7]

There is a voltage of 150 kV, but it is very rare.

[kdale1980]

You'll be surprised, but there is such a voltage class. In Russia, the following voltage classes are used: 110, 150, 220, 330, 400, 500, 750, and 1150 kV. And 150 kV is not that uncommon, especially in areas that were once part of European countries. Yes, there is only one 1150 kV line here. And as far as I remember, it doesn't operate at that voltage anymore. But I could be wrong.

[lexat7]

I'm not surprised
Your address was wrong.

[kdale1980]

I wasn't writing a reply to you, but to dmi.pris1. But for some reason the message was sent as a reply to you :)))

[dmi.pris1]

I repeat once again. There are no 150 kV power lines. It is quite possible that there used to be. I have not seen any since the mid-80s, when I started working in the energy sector.

[Andrey Nikolaev_4]

In Dnepropetrovsk there is one like this: "150 kV
A rare voltage class, within the CIS it is used only in Dneproenergo, the Kola Peninsula power system, and Magadan."

[kdale1980]

Young man, you clearly live in a different reality :)) Tell us about the lack of 150 kV power lines for residents of the Kaliningrad region, Karelia, Murmansk region, Arkhangelsk... and other regions...

[Andrey Nikolaev_4]

A 220 kW transformer produces 150 kW of power??? Does it have a current of 0.7 amps?

[kdale1980]

So, you clearly need to re-read the physics curriculum. It's clearly written in black and white – 150 kV, not kW. Don't confuse voltage with power 😂. And 150 kV networks are common in both Europe and the former Soviet Union.

[Andrey Nikolaev_4]

Where does it say? "The reports say it's about a transformer (in the Ukrainian interpretation, 150 kW) at a tire factory."—go to school yourself.

I would say the main thing is to crow louder and faster than everyone else.

[Rostislav Prokopenko]

150 kilowatts is still not enough.
The tire plant definitely needs 150 MW.
A transformer like this burning is a beauty...

The blue glow in the Dnieper was caused by Ukrainian LGBT people.

[Bamse]

When we had a short circuit at our substation a long time ago, someone also saw a UFO. Two kilometers away from the substation, with windows facing the other direction, the flash of light was clearly visible, and the sound was too.

[ALCA056000]

No... the "violet rays" turned blue

[knn54]

As Pushkin said: "Not a mouse, not a frog, but an unknown little animal"...

A bottle of blue arrived and the sky turned blue. Then the light in my eyes faded.

In Dnepropetrovsk (Dnieper) is the largest synagogue in Europe... It seems that devout Jews, from the so-called "Dnieper", simultaneously released gas in fear... That's how the "bulge" with a blue glow appeared... And then... The martyr flew...

It's impossible...no one has yet managed to clearly and thoroughly photograph a UFO...many have seen this phenomenon, but there are problems with documentation.
Regarding the glow in the article, it could be air ionization as a result of a high-voltage discharge.
It is possible that the attack hit a 750 kV substation... and there, when the equipment was damaged, breakdowns occurred along the line.

[Sergey250455]

The line protection should trigger there. Then it'll turn on again and the power line will shut down.

[Same lech]

Quote: Sergey250455

the line protection should work.

The key word is "should" ...but for some reason it may not work.

[Sergey250455]

It can't work only in one case, if it's been ruded to the point of cessation, so that it doesn't work

[kdale1980]

Believe me, it can work in different ways... It can work in such a way that it will extinguish not only the substation where the accident occurred, but also several other lines connected to it... Here, as they say, a lot depends on the settings on the relay protection and the designers who once synchronized all this

[ideo098]

It also depends on who operates the power grids. The protection equipment could have been European-made by now.

[kdale1980]

How is the European version different from the one we have here? In Russia, many substations are built using relay protection and automation systems from Schneider Electric, Siemens, ABB, General Electric, and others. So, the calculation results and the choice of settings are what really matter, along with the incompetence of the commissioning technicians.

The text of your comment is too short and in the opinion of the site administration does not carry useful information.

If transformers explode like this at 150 kV (in a yard transformer booth it is 2-5 times more powerful), then what will happen if a 200 MW city substation transformer explodes?

[Same lech]

The oil in transformers burns very well... Fires in such booths are clearly visible in the surrounding area.

[Winnie76]

A transformer's power is measured in VA (volt-amperes), but that's a bit of a stretch. Everyone gets it. But 200 mW (milliwatts) is really jarring.

[kdale1980]

Well, in the data sheets they usually write the power in VA... But VA is easily converted to W and back... so there is no particular difference in what the power is written in.

[realist]

There's input voltage on the transformer and there's a load that the substation nominally supports. The voltage is in volts (kilovolts), and the load is in volt-amperes. But everyone understands that where there are volt-amperes, there are also kilowatts! Everything is interconnected....

[dmi.pris1]

Electric power is not your area of ​​expertise, I understand.

[kdale1980]

Oh, this is where things get interesting. I remember how in St. Petersburg, at one of the 220 kV substations, in a closed switchgear, the input to a similar transformer blew... Well, in the area, the power was restored within an hour, having been supplied from other substations... But the outer wall of the building then took a long time to repair... All the brick collapsed.

[kdale1980]

The courtyard transformer booth contains a 6-10 kV transformer. Don't confuse voltage with power. The transformer in the courtyard booth is several times, if not dozens of times, less powerful than a 150 kV transformer. And there are plenty of videos online of high-voltage transformers exploding.

[helilelik]

We ended up in a liquor store. The booze exploded.

[Bear]

It certainly looks like a short circuit at the substation, or maybe they used the "Alabuga"?

Is the author confusing kilowatts with kilovolts? 150 kW is very little; that's only 10 houses with a 15 kW limit.

[Earl]

It looks like the Krivoy Rog drug addict's ass just went ballistic.

[Monster_Fat]

A transformer in the gardening community nearby caught fire - it happened in the spring, and there was a similar glow.

I agree that this process will not be quick, but we have no other options for them.

It was just a blue fox that came running

[Vertuhai 2003]

And I said from the start, if you're taking the Topols off combat duty and replacing them with Yars, then unscrew the nuclear warhead, pack it with a conventional one, and launch it at Ukraine. I'm sure even a conventional warhead, in this design, would be enough to create a crater for the Ukrainian Nazis that will eventually replace the Black Sea for them, access to which Russia, God willing, deprives them...

[Reptiloid]

The Dnieper is wonderful in calm weather, when it carries its waters freely and smoothly. NV GOGOL

and what is this.

[drroc]

Once, when I was young, a substation shorted out in a neighboring village. The glow was similar, only smaller. It's very beautiful in real life, but it's as fleeting as in the video. More sights like this for the Ukrainians.

[Mazunga]

This is Dnepr Pride coming out for the night parade, and there are blue lights and all that stuff going on.
