Why can't 240v be the only standard and get rid of all other similar voltage?

I'm not an electrician. what's wrong with 240v? additionally why do they have 220v and 230v as separate systems? I think almost all electronics can tolerate give or take 10v.
>>
>>107022289
it should be 480V desu
>>
>>107022650
>what's wrong with 240v
Nothing. 240V in the US is two phase and should be compared with 400V three phase elsewhere in the world. Of course the NA three phase standard for industrial is 690V but you still need to lug around a 120V supply for all the other equipment you want to use.
>additionally why do they have 220v and 230v as separate systems?
They don't. 230V is new standard 220V is old standard. The bump to 230V was to be more compatible with the other 240V standard (Oceania) which is also adopting 230V as their new standard.
>I think almost all electronics can tolerate give or take 10v.
They can. Typical supply tolerances are more than +-5%.

>They can.
I should add that most 230V electronics won't be designed for a 240V US supply and lots won't be compatible. If they are designed for compatibility then it will take something like 100-250V and still may not be designed for a 240V US supply.
>>
>>107022650
Nothing, the voltage margin in my country is 5% which at the rated 230V can go up 241V
Modern power supplies especially class D can tolerate much much more
My house has spikes of up to 250V sometimes in summer because I have 20 kW in solar panels and three different models of inverters (because I got them from scrap) and I have never had significant issues, most importantly my PC power supply has absolutely no complaints, no weird voltage spikes or anything like that, it's a heavy corsair brick that will outlive me so that's nice
You're more likely to have some retard mess up rebuilding your electrical box and pushing 420V into your refrigerator than for the innate instability of the power grid to fry anything, it really is the most impressive contraption humanity has ever thought of

10% not 10V. Typical 110V power supplies are rated 100-120V. The ones rated 100-120V (that work in Japan and USA equally) are rated 85-132VAC internally.
Same for 220V European power supplies, they were 220-240V normally, while the 220-240V ones can go as far as 170-264V internally.
These are values I've seen on actual power supplies mind you, not something randomly computed.

Normally when using higher voltage, you just have the power supply running slightly hotter, and that's about it. So when we had our system bumped from 220V to 230V, everything worked the same.
>>

The US actually uses both but the 220V in houses is typically only for clothes dryers and electric stoves. It has a much larger plug and heavier wires.

We invented electricity, and established the standard for it. Then eurofags decided to create their own standard for no reason. Maybe if you find one you can ask them why they don't like compatibility.

>>
>>107022650
There were concerns over safety vs reactive demand on transmission lines in the early days. 60Hz is easier to phase correct because shorter waves, but it cuts through the human body more easily so they halve the voltage. In Japan they have 100V 50Hz following the same logic.

>>107022752

No. Split phase means they split the same phase. It's a 240V, center tap transformer. There are like 6 companies in Boston running actual 2 phase power, built by old man Westinghouse himself.

No, because you have higher energy loss rates with higher amps vs volts.
It's why a tiny prong on a stun gun can be x1000 volts, but higher amps will melt the cables.
>>
>>107024550
240v at 1 amp is more efficient than 120v at 2 amps, because your wiring can handle basically whatever amount of voltage, but not amps. If you touch electrical wiring in your house and die, it's the amps, not the voltage that will kill you.

We don't. It used to be 220V then the standard got raised to 230V at one point.

>>107022650
>I'm not an electrician. what's wrong with 240v?
Nothing. And it's what sane parts of the world - i.e. Europe et al - actually use for a single phase.
European homes typically receive three phases of 240V each whereas US homes only receive two phases of 120V each.
As a consequence, In Europe one can have much heavier appliances running concurently without blowing a fuse.

>additionally why do they have 220v and 230v as separate systems?
They don't. It's a sliding scale of "somewhere between 220V and 230V" and actually that metric is about a decade and a half behind the times.
Europe largely pushed itself to 220V - 240V instead.

The US standardizes on 120 V at 60 Hz and offers two phases, combining to 240V maximum consumption if you have a fuse box wired correctly such that an appliance can bundle both phases. Combining phases in this system is shitty though and much MUCH more prone to failure and blown fuses than in the European three-phase system.
The European system standardized originally on 220V at 50 Hz over three phases, which upscaled slowly to 240V at 50 Hz over time combining to ~520V maximum consumption due to partially overlapping phases but leveling out load a bit and making the entire system more resilient against blown fuses if appliances have decent enough power train to load-level across phases,

The reason Europe went for higher voltage and lower frequency is it suffers less from the skin effect, i.e. less actual power loss during transmission over time.
The reason the US went for 60Hz is because it allows transformers to be physically smaller and use cheaper parts and less resources. As is usual with these things, the US went with short term gain over long term gain.
>>
>>107024134
Most EU sets after the first few generations supported PAL60 or SECAM, which had 60 Hz output combined with all the benefits of color fidelity and visual clarity that the PAL signal composition had over the shitty ill-devised NTSC signal.

Also 50 Hz is actually closer to the 23.976 used for film, which meant PAL regions actually got an experience with movies far, FAR closer to their native recording rate than NTSC where all kinds of fuckery was needed to make it work. PAL could just upscale the entire movie's speed by slightly over a single frame per second which is all but unnoticeable. Whereas NTSC required pulldown trickery, frame removal, and frame duplication. Often leading to jitter, judder, and stilted motion in badly mastered materials.
>>
>>107022650
>I think almost all electronics can tolerate give or take 10v.
They can and voltages are never that precise.
Roll out a long wire and you'll easily drop 10V.
As mentioned most countries settled for "230V" now as a good middle ground that all equipment handle but when you actually measure it at the outlet it might be 235V or 225V or even a bigger deviation.

>>
>>107026745
>time combining to ~520V maximum consumption
And FWIW - that's about the theoretical ideal maximum. No system in practice is going to actually be engineered to require that. Everything tops out at 400~440V instead, which means combining phases rarely if ever leads to problems with blown fuses. If that happens, you're dealing with a badly engineered appliance or a badly wired fuse box.

As an electrician once told me: there's roughly speaking three ways to wire a three-phase fuse box:
1. The right way
2. The wrong way which can result in fuses being blown.
3. The wrong way which can result in your house catching fire.

(The latter two are nearly exclusively used by either a) idiots that don't actually know what they're doing, or b) asshole construction firm contractors that know those bad ways take less time to wire and cost less material, i.e. are cheaper.)
>>
>>107026745
Pretty sure 50Hz vs. 60Hz wasn't a conscious decision.
Both worked and some equipment maker happened to use 50Hz and others happened to use 60Hz.

Just like with railway gauges it was initially all small local systems and nobody thought about linking them up.
And when they did finally link up the systems they just used whatever happened to be most dominant, not what was best.

Japan happened to end up with 50Hz on one side of the country and 60Hz on the other side.
IIRC this was because one side used mostly Westinghouse equipment and the other side mostly General Electric.
>>
>>107026883
>Pretty sure 50Hz vs. 60Hz wasn't a conscious decision.
It actually was.

Back in Europe at the time AEG established the standard of 50 Hz because it operated better with less overall flicker in lightbulbs than the 40 Hz used in earlier trials on experimental power grids and it propagated from there. Their choice was based on retaining the low-voltage, high current paradigm as much as possible.

Westinghouse in the US meanwhile, pushed for 60 Hz because it allowed reuse of existing AC motors in industrial applications and existing arc lighting solutions. And as a convenience, it allowed cheaper AC to DC conversion.
General Electric concurrently had a project running at Mill Creek to establish a grid as well, planned for 50 Hz, but were under pressure to align with Westinghouse so they caved and for reasons of marketability decided to bend the knee and adopt Westinghouse's 60 Hz standard.

>>107022752

That's still pretty random.
If G.E. caved to Westinghouse instead then America would have had 50Hz.
And if AEG decided 50Hz was still too much flicker Europe might have had 55Hz or 60Hz or 65Hz or whatever.

It was just what random companies preferred and not some well thought out standard based on science or policy making.

The high voltage grid across Europe still runs at 50 Hz. It's the pairing of lower frequency with higher voltage to carry comparable power levels to the US's 60 Hz, while reducing the skin effect which matters.

I have no fucking idea how that would happen but I know PC PSUs leak a little to earth as part of the noise filtering circuit and that's the only thing I can think of that could possibly cause such a thing.
Take the socket out and jumper the earth and neutral pins. If you don't have an earth contact get a socket with one and install it like that. It'll solve that problem.
This shouldn't produce mustard gas if your neutral connections are all reliable.

Much of Europe was 120V in the past. Doubling the voltage allowed reuse of undersized mains infrastructure, a benefit to an impoverished post-war continent. 120V is safer, and is still mandated on job sites in the UK and Ireland (yellow CEE sockets). 230V is a cope: efficiency/cost savings in exchange for lower safety.

If that statement is false then explain how it is.

My house, like all small residential buildings, gets three phase wires and a neutral wire from a transformer nearby. Phase to neutral is 230 V. Phase to phase is 400 V. Lines at a frequency of 50 Hz and offset by 120 degrees from each other. All my stuff runs on 230 V single phase, 230 V three phase, or 400 V three phase.

Now I've been trying to figure out how the burger system works, but supposedly it's such a clusterfuck that no one can seem to give a simple explanation.
>>
>>107034789
There're 2 ways to connect 3-phase transformers, Δ (3 phases floating, they might have a center pole for each phase) and Y (3 phases + shared neutral pole).
>>
>>107034789
It's single phase transformer with a 120/240V center tapped secondary. Electricians like to call it 'split phase', which makes people imagine there's more than one for some reason. In a 2 phase system the phases are 90 degrees different instead of 180.
>>
>>107034956
Might have?

Does that mean you have residential transformers at both delta and star configurations? Are the phases always 240 VAC @ 60 Hz?

The only advantage to metric is that it's easier to calculate manually, which is a moot point now that literally everyone has a calculator at all times. Most of the units are awkward to use in actual practice.

midwit take. Even if you had a magic generator that generated 1V 100A of electricity somehow, it would do nothing to you because of your body's high resistance, current won't flow to your body amps will be low.
A flyback transformer inside a 12V portable CRT TV generating 10kV 1,2mA of electricity on the other hand...
>>
>>107042544
1.2 mA is below the lethal threshold. Electrostatic discharge don't kill people, at least not usually and it's 5 - 50 kV but low charge because neurons don't 'react' to voltage but to current (and it depends of ΔT), it's obvious you need a min voltage to reach that current, but skin resistance is the main factor and it varies a lot depending on the conditions (from few hundred Ω to ~10kΩ iirc), beyond 50-60 V it's dangerous (worst case) but a pacemaker barely needs 12-20V at maximum to control the cardiac muscle.

You would never ever get a current of 100A through your highly resistant body with just 1V.

The difference between NTC 60Hz (aka 60 fields interlaced / 30 frames progressive) and film's 24p (24 frames per second, progressive) is 6 frames per second.
The difference between PAL 50Hz (aka 50 fields interlaces / 25 frames progressive) and film's 24p is only one frame per second.

In PAL's case, film could simply be sped up to 25 while retaining all footage. An increment of ~4% that is almost imperceptible.
In NTSC's case, the gap is too big and closing it that way is a 20% speed increase which is VERY noticeable. That meant you needed to use more complicated pulldown and frame decimation methods to make the 24p port over to 30 FPS progressive / 60 Hz interlaced.


Also, PAL both had higher resolution AND greater color fidelity than NTSC did.
As for the world having moved on to 120 Hz: in actuality the world has moved on to fluid panel refresh rates with GSync and Freesync. Which means PAL-50 material plays back perfectly fine. No problem whatsoever. (Also; you forgot to rant about PAL-60, which is the much higher quality PAL signal at NTSC's 60 Hz.)

>EU lives on resourceless peninsula where there isn’t enough fossil fuel to go around
Europe has fucktons of coal in Germany and the Netherlands is sitting on top of one the largest repositories of natural gas in the entire fucking world.

The problem isn't the availability of the resources. It's the extraction of them causing irrepairable environmental damage and the problem of population density giving that a fairly if not immediately direct effect on the health and wellbeing of the populace.

It's true though. Celsius is worthless for temperatures under 50 if you're accustomed to using both.
>but what about freezing
Who cares? -40 is the same on both. If it's over -40 it's not that cold.
