>The system of three-phase alternating current electrical generation and distribution was invented by a nineteenth century creative genius named Nikola Tesla. He made many careful calculations and measurements and found out that 60 Hz (Hertz, cycles per second) was the best frequency for alternating current (AC) power generating
And yet euroretards decided to use 50hz for everything. 50hz is headache inducing for light bulb and CRT monitors/tvs.
All USA/Japan homes can get 240v from the line transformer. What happens is other than air conditioning 220~240v is not needed so the house is wired for 120v except 1 or 2 sockets And to make things worse the european companies convinced the entire world to go with shit 50hz cycle
>it's another "ameritards think the world should work the same way at their shitty country" episode Sage and hide.
Ryan Martin
>can't give one single logical explanation why 230 or 240 at 50hz >cry like a faggot well even fucking China and Russia decided to use 220v at 50hz because it suck less for 50hz than 230 and 240 Eurocucks never ever!
Ryder King
240 is within 10% of 220, not even such a big deal. Certainly a smaller difference than that of 100 and 127. If you want to criticize something, go for the Hz, you might have a point there but the volts? lmao

Nikola Tesla was renowned for his careful calculations and measurements which lead to him dying poor.
You mean Nick Tessler, the famous Canadian scientist?

What do you even use your electric kettles for? I have a stovetop kettle that I could use on my gas range but it's been sitting in the cabinet unused for years now.
Elijah Torres
This is trivial to check. Just go to an online retailer that sells NA products and look for electric kettles. Behold the legions of electric appliances.
Parker Powell
Doesnt even fucking matter in todays electronics
look at your laptop adaptor or your refrigerator. it supports every possible kind of current/hz
Benjamin Garcia

Aaron Hill
50Hz was easier to implement at the time and by the time 60Hz was determined to be better there were already too many 50Hz systems out there to change over. Same reason America and many other parts of the world use 100-127V power.
Ryan Cook

Literally doesn't matter. Virtually all devices use DC and those that don't (including AC/DC transformers) also don't care about the frequency.

We have them. We just don't give a shit or use them as we have fuck huge kitchens with better appliances.
Jeremiah Young
yeah, you have huge everything, to store lots of unnecessary advertized shit
Carter White
why did we decide to use AC instead of Edison DC? Edison DC is safer, better and more durable Today's AC provide 113~124v while we could have had 110v DC
Grayson Lewis
so how often do you plug an electric motor into your electric socket?
David Hill
Well, I have a lot of woodworking and machine shop equipment that runs on electric motors and gets plugged into electric sockets.
Blake Perez
>uh you have unnecessary stuff >but hahaha we have electric kettles
They don't care. Synchronous speed is far above loaded speed, mechanical power depends on electric power input but not frequency. BLDCs work off a transformer, they don't care. >inb4 running synchronous motor off of mains Don't even go there m8 that's beyond full retard.

Long distance distribution. Having a power station for each square mile gets unwieldy quickly, and denies economy of scale.
Gavin Murphy
And even not including the shop equipment my clothes washer & dryers have electric motors in them as well as my vacuum cleaner, blenders, stand mixer, dishwasher, refrigerator, and HVAC system all have electric motors of some sort in them.
Jaxon Barnes
Spoilers: they're all async motors and they don't care about frequency.
Blake Watson
who cares as long as we have the better non-retarded socket
tea and other hot beverages actually cool you down
There is no easy way to convert 10-500kV DC for long range transmission to 100-200V DC for residential use.
Austin Cook
Flicker under 90 hz is visible in periphery.
Kayden Martin
>Japan one half of the country bought their power system from germany and the other half from the us the fucking idiots never bothered to settle on one frequency
Matthew Jones
There is, a buck converter. Getting it to 500 kv from 400 v is the challenge.
John Hughes
Japan imported different generators for different regions of the country, so half the country was using 50Hz and the other half 60Hz. For some reason they never merged it. No fucking idea about Brazil
Levi Anderson
yeah okay, the next time it's 40C outside go ahead and drink a big, hot cup 'o tea and tell me how refreshing it is
Leo Reyes
The most commonly used type of motors for machinery are induction motors that DO care about frequency. If the speed has to be controlled, they use a variable frequency drive.
brazil is 60hz (127v~220v) almost everywhere except in some states it's 220v (1 hot 1 neutral) only
Brandon Sanders
And they all run off their own variable frequency drive inverter, not directly from a fucking wall socket.
Daniel Anderson
what about adapting the AC line transformers?
Jackson Nguyen
>And yet euroretards decided to use 50hz for everything. It was 16 2/3 back then. So it is a progress

William Howard
Three phase 127V? We had this shit is Soviet Union.
Nicholas Adams
Canadian here, this is actually something I found very strange when I went to the United States for my masters. In Canada almost everyone has an electric kettle, but I saw maybe a half-dozen other than my own the entire time I was in the States. It's kind of hard to even find them for purchase at retail in a brick-and-mortar store. One of those things which reminds you that you're a stranger in a strange land.
I find the electric kettles are quicker at boiling water, and they don't heat up your kitchen as much as a range.
Also water for coffee in a french press. I stopped using electric coffee machines after becoming redpilled on how much bacteria and other crap they have in them. And frankly, FP tastes better anyways.
Isaiah Peterson
>and more durable Thicc wires aren't durable. Thin 1 000 000 V wires are better, also they kill retards, so it is a good thing
Aiden Powell
>or your refrigerator. It has motor that is designed for 220-240V 50 Hz. So no. It matters.
Luke Richardson
Japan is 55hz, "good enough" for the 60hz amerifats and europoors never complain about their anal intrusions Brazil has no electricity
Jacob Rivera
We use both 50/60 hz in Argentina
220 of course. Anything else is plebeian shit.
Evan Miller
Do you have schuko or italian butt-plugs?
Nolan Murphy
I said "easy". Buck converters don't scale up well to high-voltages since you have to stack thousands of p-n junctions. Also AC was chosen many decades before the semiconductor was invented.
Aiden Miller
According to your own regulations, it has to be 50Hz. If you're provided 60Hz, your distribution company is fucking up you argensimian
Nathan Richardson
Motors that don't require speed control ARE typically wired directly to 3-phase AC through contactors. VFDs aren't cheap.
Transformers only work with AC.
Jonathan Kelly
>insulting the serbian born inventor of the modern world on a machine you use to watch IR cuck porn >it runs on AC Your wife may belong to Africa now eurocuck, but at least you've shown you can still own yourself.
AC is far more convenient, simpler, and safer way to distribute electricity. If you interrupt AC it turns off, if you interrupt DC it will arc. DC is only good for long distance distribution where the lines do not get interrupted.
Kevin Johnson
60 hz is better, but 120v a bit sucky compared to 240v.
Eurocucks need to realize we are making much more progress as a society than you.
Hudson Roberts
This guy watches AvE
Josiah Powell
Motors that don't require speed control are asynchronous and will be able to start from 60 hz AC. If you plug synchronous motor into 60 hz mains it will not start and then melt promptly. There are sync motors with a squirrel cage mesh to start it asynchronously but with advent of VFDs they are being phased out, now that their only advantage doesn't do anything but increase the cost. Also you still need to control the power line because it takes longer to start than to melt at stall currents
Juan Gomez
>it boils 1 liter in like 3 minutes. LMAO fucking voltlets
They run async motors. Honestly, those are the best. They can run without a speed controller, they're cheap because the rotor is basically a dumb brick of aluminum with copper veins, and if you got a speed controller you can generate torque extremely efficiently at any speed.
Anthony Jones
88hz with 666v is the way to go.
Jack Rivera
Is there anything americucks won't whine about?
Dominic Hernandez
I hope you're not trying to insinuate that Nigel Tesshire was Canadian. He was a proud Anglo-Saxon!
Gabriel Stewart
>Motors that don't require speed control are asynchronous and will be able to start from 60 hz AC.
They will start, obviously, but they will rotate 20% faster (unless overloaded and slipping), which tends to fuck with the operation of equipment.
John Allen
>Hz irrelevant >127 V This is probably one of the worst engineering decision in history.
David Jenkins
>If you interrupt AC it turns off, if you interrupt DC it will arc
Only if unloaded. Slower rotation with the same inductance means more torque. At load conditions the speeds are about the same. And no one cares about unloaded speed, it's irrelevant for a motor, a device which entire reason to be used is to drive a load.
John Diaz
I believe it is three phase 127v so shower is always ~220v the rest of the house is 127v
Nathan Miller
two red (hot) wires or 1 red wire + neutral + ground (earth)?
Ayden Green
fair point user however I don't think AC is safer
Jaxson Lewis
Soviet Union standard for three phase electricity is 380 volt.
Brody Anderson
Okay I'll admit I was too simplistic with my explanation. Electricity whether AC or DC will always arc to some extent but AC is more controllable because it drops to 0V 50-60 times a second. DC does not ever drop to 0V so unless everything is removed from the circuit and there's close to zero current flow the electricity will always try to keep flowing across and it can burn up the contacts on the breakers. HVDC systems would be more expensive to maintain.
Bentley Stewart
do your eyes not fucking work? you can even see flickering at 60hz if you even marginally look for it
Austin Wilson
3-phase induction motors retain almost the same rotation speed through a wide range of loads (including unloaded), which is 95-99% of synchronous speed, and dependent on AC frequency.
>those that don't (including AC/DC transformers) also don't care about the frequency. Transformers is one of the places where it counts. The reactance of an inductor increases 20% from 50 to 60 Hz.
Logan Bell
It's a question of mortality from electric shock vs mortality from fires caused by electricity.
But anyway, the lack of a cheap and reliable DC equivalent to a transformer makes a DC power grid pointless, so the difference is moot.
