What does it actually mean to disconnect? Is there some physical connection being broken? How is that done?

#22The interesting bit is that this includes Kaliningrad. See: https://www.kyivpost.com/post/46628
Very cool! I couldn't tell from the article if Kaliningrad will remain on a grid with the Baltics or become its own island.

#23I like the site.
Unfortunately for this American, having a different set of standards for mathematical notation tripped a "don't these people know the difference between Hz and kHz?" impulse in my brain.
To illustrate: When an American sees "50,000 Hz" we process it as you would process "50 000 Hz". This misunderstanding could be corrected by using two or four significant figures after the decimal. That's too much to ask though, probably requiring a large number of hours to accommodate someone not even from there.
Your site is fine, it's our brains that are more appropriately adjusted. A little disclaimer link or something would help a number of us understand. A large number of otherwise intelligent and educated Americans don't realize this difference in notation and this would be a great opportunity to educate them.

I am European and I dislike the use of comma, too, and I use dot everywhere. I see it as "50 000" as well, as a non-American. :P
Re: Baltic countries disconnect from the Russian power grid
#25On Saturday (8th of Feb), Baltic countries will disconnect from the Russian power grid and synchronise with the Continental European electricity system. They will operate in "island mode" for 33 hours, and then synchronize with the European grid frequency. The frequency is a key parameter of the grid. If there is too much load, it goes down, and if there is too much production it goes up. A lot of critical grid infra…
Off-topic; Why does America use 60Hz? I've never found a satisfactory answer.
> They were disposed to adopt 50 cycles, but American arc light carbons then available commercially did not give good results at that frequency and this was an important feature which led them to go higher

Better question is why did Germans pick 50 Hz, I'm not aware of any comparable benefits of having lower frequency

Especially when the number format on the dial doesn't match the number format on
the chart.
Re: Baltic countries disconnect from the Russian power grid
#27Did they consider connecting to both grids at the same time making a bigger 'supergrid'? If there is insufficient connectivity between the grids and the connections all disconnect due to overload, you just end up back in the two-grids situation that they have planned anyway.
The goal of this is to economically and politically isolate Russia and prevent anything in Russia from affecting the Baltic states

The site is confusing, even as a European: both periods and commas are used as decimal separators.

A better question is why does Japan use Both 60 Hz and 50 Hz in different areas? And that’s really just a legacy from early decisions at different companies when the grid was first introduced, and there’s never been a sufficiently compelling reason for either to swap. 60 Hz is slightly better in terms of flickering, but neither has enough advantages to really be a determining factor on their own.
US did the same, Southern California was 50 Hz at first. It didn't convert until after WWII

Yes good point! We only had the idea of making this site a few days ago so the UI could use some tweaks. Thanks for the feedback.
UPDATE: made a small PR and fixed it. For now it's most consistent to just use dot separators everywhere.
