Why are there different electrical standard? And how does 50/60 Hz affect electrical devices?
Tripfags (especially vomit-chan) are not allowed to answer
Why do you keep making this thread every day?
Why are you such a faggot?
Do your parents hate you?
>>51922555
why having this fucking thread EVERY day?
240V is practically superior to 120V, the reason 120V exists is because the USA had electricity far before Europe, and even when Europe had it WW2 recked it all so we could build more modern infrastructure.
>>51922555
Look at Japan... LOOK!
>>51922668
Japan has two standards because historically the electricity was maintained by two different companies with their own grids. The difference isn't really that big these days though it mostly comes down to the size of the transformers and how fast the generators run. Almost nothing directly uses the frequency anymore.
>>51922555
> Japan has two electrical systems
Nothing is easy in that country, is it?
>>51922626
60hz is still better than 50hz for analoge crap. It ruined so much that 50hz

To be honest, it IS stable. Look at the Hz.
>>51922555
>brazil has both 240V and 120V system
just what the fuck is happening there?
>>51924495
Actually not a big of a deal, most of our everything works with both 220/110v and we (used to) have universal sockets that fit both euro and american plugs
Tldr brazil is master of at least something
>>51922626
>It took a world war to modernize Europa, a third one is required for rest of the world.
While we are at it, dear the third world, what's your excuse not to adopt the divine Schuko?
No wait, you can't you. My my, enjoy your hellish contraptions and ticking timebombs.
>>51924879
My country adopts Schuko desu.
Talking about plugs, China is one hell of a clusterfuck.

Don't you know it is the one standard to unite them all?
>>51924939
China is largely settled on a modified Type I now.
It's upside-down compared to Australia/NZ and has slightly thinner prongs.
220v/50hz is also standard.
>>51924495
Brazil is easymode though, it's only double the voltage.
Nippon fucked itself with different frequencies, that's much harder to cater for.
>>51925654
What is the difference between 50/60Hz tho?
>>51925670
+/-10Hz
>>51925695
I meant, is there any implications between differing freqs?
>>51925708
Higher frequencies can use smaller transformers. Generators have to run faster for 60Hz, a motor would run faster on 60Hz
>>51925670
The frequency of the sine wave, remember - this is AC power.
50hz AC, The sine wave peaks 50 times a second, 60hz AC, it peaks 60 times a second.
It's much, much harder to convert 50hz to 60hz or vice versa (well, it's not 'hard' it just takes more equipment, which costs money to buy and maintain and then costs you some of the electricity as no electrical conversion is 100% efficient.)
120v to 240v is pretty easy, either use a voltage doubler (lot of older PSUs did this for 220-240v countries, that's why on those old PSUs if you turned it 240V in a 120V area, it simply wouldn't work, but if you set it 110v in a 240V area, you'd blow the thing sky high)
USA does 240v from 120v another way, they have a 2-phase system where the active and what would norammly be neutral are actually both active and are 180degrees opposed - so instead of the range being 120v (0v at the bottom of the sine wave and 120v at the top) it was 240v (-120v at the bottom of the sine wave and +120 at the top)
>>51925708
yes, because the transformers you use to transform it to DC(so its usable in basically any application)depend on the frequency
>>51925739
US is not two phase it's single phase. Two phase is not used anywhere anymore its either single phase or a multiple of three.
>>51925734
So.. why 50Hz is more popular...
>>51925864
50Hz generators were cheaper to manufacture apparently which lead to them being more common. Replacing them at this point would suck though. You cannot just add 60Hz generators to a 50Hz grid they would go out of sync and short. You have to synchronize them somehow, Japan uses HVDC to connect its two grids together. Also for regular people older devices could run too fast or too hot at higher frequencies which could damage them.
I'm just waiting for vomit chan to show up.
>>51922555
240v 60hz is better, but in the end every device just transforms it into what it needs.

No.
>>51922555
>Why are there different electrical standard?
History. Usually people pushing their own standard are involved.
>And how does 50/60 Hz affect electrical devices?
This depends on what we're talking about. If the device runs on DC it includes a converter and most likely doesn't care.
Examples: computers, TVs, audio systems
If the device uses AC directly then it's most likely used to power a motor. The change in current frequency would cause the motor to run faster/slower depending on what frequency it was designed to run on. This could lead to overheating and possibly damage.
Examples: washing machines, vacuum cleaners
Some devices aren't affected at all, as they simply require current to run through a resistive load.
Examples: classic light bulbs, heaters
>>51922555
because americans are stupid
>>51925812
USA is split phase. A standard breaker panel has two 120v lines coming in that are 180 degrees opposed. This allows you to wire 240v circuits for large electrical appliances like water heaters, dryers, electric stoves, and ac\heat pump compressors.
>>51922668
It's far more common that your shit will support both 50 and 60Hz than will support 100-240 but now days you get a lot of shit that does support both.
It's practically not an issue. Most of the shit I buy in NZ that has an adapter is 100-240V.

Science and engineering does use the metric system here. but for the man on the street there's no benefit in switching all the road signs to kilometers.
>>51927117
Actually, even the imperial system is defined now by the metric system, so the imperial system became a variant of the metric system.
>>51927580
Being an anime avatarfag is 100x worse than being a reposter.
>>51926981
Pretty much but split phase is a kind of single phase. The two hot wires are the same wave form just on opposite ends of the transformer.
Why would Japan do that do itself?
>>51927228
>>51927622
>>51927725
Y'all now know that imperial and us standard aren't the same measurement system.
There are a whole bunch of differences (the biggest are in volume units). Heck even the inch was different between the two until it was adjusted in the fifties (leading to the usa having two different kinds of miles)
>>51929469
like what?
>>51930651
Gallons (3.79 liters for US 4.55 liters for imperial this carries down with differences in the ounce, but most of it is because the usa gil -half cup- is 4 ounces and the imperial is 5 ounces), tons (2000lbs usa / 2240 uk -the british hundredweight is 8 stone or 112lbs while the usa hundredweight is a logical 100lbs), miles (surveying for usa is its old mile before the international mile was adopted), dry volumes are different (bushels, pecks, etc.), us standard recognizes pennyweight
There's probably more, but that's more than enough.
>>51925431
Of coulse. Amelican piggu has nukurear bombu. How dishonorabuu
>>51927670
Except knowing that at 100km/h the distance in km equals the time in minutes it will take to reach a certain destination.
>>51930933
I always thought it's quite a shame Japan surrendered so quickly. The USA had two bombs, after that it would have taken ages to build a new ones. Japan could have made it.
Then again Japan was stupid enough to fuck up pearl harbour, to fuck up the battle of midway and to fuck up the the battle of the Coral Sea.
So many mistakes deserve punishment.
>>51931366
If only Soviet occupied Japan..
>>51925431
No shit. That's the reason China backs NK and builds islands in the sea. They don't like America having 2 of their vassals so close.

Wouldn't that be 60 km/hr since there are 60 min per hour? Shit man, you eurofags really do need the simplest measurement system possible.
>>51931366
It took less than a month from the trinity test to drop fat man on Nagasaki. They could have built another in that time period.
>>51932602
>Wouldn't that be 60 km/h
Jesus Christ amerifag education..
>>51931402
Er, at the time Germany had already been defeated and Russia had basically transported their entire armed forces to attack Manchuria.
Russia was practically knocking on Japan's door when America dropped the bombs.
>>51922555
Why does it matter?
Any device that can't use all standards is probably fixed in a building anyway.
The only people that would care about their standard are people starting a new country. They would pick it for political and economic reasons over technical reasons anyway (like you wouldn't use 230v 50hz if you were wedged between canada and the usa).
>>51922555
>And how does 50/60 Hz affect electrical devices?
Totally screwed up analog TV. Leading to the hack of telecine on 60hz in North America and running movies at 25fps on PAL.
>>51932795
>Any device that can't use all standards is probably fixed in a building anyway.
That's an absurd claim.
>>51932842
I'd argue that it'd be easier to just change the standard for film to 25fps.
That way all video is based on a multiple of 25. It'd simplify television, film, the lot.
Too bad people didn't care enough to do it back in the 40s/50s, and it's too late now.
>>51931275
>at 100km/h the distance in km equals the time in minutes it will take to reach a certain destination
>>51932908
I went looking through my apartment.
I've found the following devices that won't accept both 50/60hz or 230v and 110v:
>fridge
>toaster
>light globes
>electric stovetop (fixed)
I'm not likely to take these things travelling soon.
The rest have both yooroup and yankee standards on their specs.
To be completely honest, it doesn't make fuck all difference who's specs are better. I'll use whatever is used. These threads are just people trying to split hairs between countries.
>>51922852
Britain might as well be in India, post France or Germany next time.
>>51922555

>>51926406
Funny side notes!
>TVs
Old TVs used the frequency for timing. That's why the NTSC was originally 60 half-frames per second while PAL was 50.
>heaters
Coffee machines are mostly heaters, but some cheap/old ones produce shitty quality because they use the frequency for timing.

>>51927117
We don't use Imperial, we use US Standard.
>>51922555
No impact on anything new, but some old analog devices took their timing from the mains, like clocks and TVs.
>>51927117
Is Burma imperial or do they use their own crazy standard?
>>51932671
If you go 60 km per hour you travel one kilometer per minute. That means it takes x minutes to travel x kilometers at that rate. At 100 km per hour you are traveling 1 and 2/3 km each minute. This shit is simple arithmetic you troll.

>>51928171
>>51922874
There is no power delivery that's not accurate since the generators being used are forced to that frequency by the power net. You can't go faster or slower but if you try anyway you'll be leeching power, not providing it.
>>51928767
>The two hot wires are the same wave form just on opposite ends of the transformer.
Wave forms that are out of phase with each other are by definition not the same.
>>51930877

There is a reason why imperial is inferior and why the rest of the world doesn't want to know this shit.

>>51934490
Absolutely right.
It's a one set of units world with a few retarded variants that only morons would ever use.
