yeah the west island bought their first generator from the germans so it ran at 50Hz, and the east one bought theirs from the americans so it ran at 60
– and then they unified the systems, right?
...
– right?
anyway that's why switch-mode power supplies were invented
Somehow it's like Technology Connections is spying on me and delivering bespoke content. I had already considered how a 240v electric kettle would work in the USA (and I probably spend way too much time thinking about our electricity supplies) but that video firmly answers the feasibility question, with a resounding yes.
One day I'll commit to having that NEMA 6-20 receptacle. It could also be useful if I get a portable iinduction wok or something like that.
I have watched so many videos on things I never thought I'd could care about such as heat pumps, dishwashers, freeze drying etc all because of this guy. His videos are great!
[Fun fact to lighten things up: people often call volts "velas" candles here. So e.g. "127V" and "220V" are often called "cem velas" (100 candles) and "duzentas velas" (200 candles) respectively. Confusingly enough some also do it with watts.]
Never heard this before, brazilian here btw.
All regular sockets in my city are 220V 60Hz. I think only places like hotels have different voltages.
Or people who have old houses, 2 pins sockets, and rip apart the ground pin from their 3 pins plugs.
Yep, my dad can't stand the ground pin in almost every plug. I had to convince him not to destroy them all.
The first time I ever used an electric kettle was in south korea for my ramen. I was like "man, when I get home I'm so buying one of these. 5 minute ramen is great."
Then I got home and bought a kettle and it took for-fucking-ever to boil. 120v is such bullshit. Give me POWAH!!!
Technology Connections just published a video about this. By the end, he's got an overclocked 6 kW tea kettle boiling water in under a minute before destroying itself.
It was early 2000s but power standards haven't changed. 5 minutes is a long time when you're used to 1:30 minute to boil. I meant 5 minutes from tearing the package to eating it not 5 minutes to boil but I can see how my phrasing was confusing.
Much, maybe all, of Mexico supplies single phase power via 2 phases from
three phase power. In the US that is known in the power industry as
"network power" and is usually 120/208 volts. Now 208 volts sucks. But
to get 240 volts from such a configuration, you'd have to have 138.5 volts
on line to neutral, and that is a bit too much for most things that want
120 volts. In Mexico they have chosen a compromise where the L-N voltage
is just a little high (127 volts) and the L-L voltage is just a little low
(220 volts).
I think it's because in a three phase system is you have 220v between two phases then you'll have 127v between one phase and the ground.
I know in France at one point before the 50s most of the country was using 110v, then some of it switched to 127v but from the 50s they decided to unify the national electrical grid to 220v. It took a while but now I don't think there is any 110v left.
IIRC, they loosened the tolerance and lowered the nominal voltage from generators to be around 235, to provide more leeway for electricity fed in from domestic solar panels without tripping circuit breakers.
It was originally, but we changed to 230 to align with mainland countries. Some older substation equipment and warning labels still state 240 if you go looking
Depends on the tool. Some things will work fine by just flipping a switch near the power plug while others will emit the magic blue smoke or melt down. If you don't know if your devices are compatible the best bet is just to get a step down converter or use local electronics.
That probably wouldn’t be a problem as the voltage is the same, but as the frequency is higher your record player will likely spin too fast. Most things won’t care as they’re rated for both 50hz and 60hz

My country: obvious and very clever choice
Your country: ridiculous and unpractical choice, borderline sociopathic
Guyana: now that is bold
(What is my country or your country? Irrelevant.)

Why does 230@60Hz exist? Using the euro voltage with US frequency must be a compatibility nightmare

Was this a while ago? I've gone through several on 120v and I don't think it's ever taken more than 5 min.

As a Mexican I thought 127V was the norm in the West until very recently

I member the switch to 230v. There was a buzz and then nothing.
Theoriginalthon@lemmy.world · 6 pts · 260d
Well the tolerance is +10% -6%, so that's 253-216v

I swear Australia just did it quietly. We could have done with that extra juice to charge our cars faster.

That's odd - all my life I've believed the UK was at 240v, yet here and in the article it says 230. My life has been a lie.
