Why 3 Phase AC instead of Single Phase???

ElectroBOOM - 2018-04-16

Seems we can run pretty much everything on a single-phase AC, then why bother with 3 phases??

Edward Grabczewski - 2019-01-06

I got a degree in electrical and electronic engineering many years ago but the theory wasn't backed up with much practice or demonstration. You've not only demonstrated the concept but injected your wonderful enthusiasm for the subject. Thank you!

All Might - 2019-09-01

It's because the professors at the universities don't really understand what they are teaching. Those who can do....

ChromerSatanas - 2019-09-30

@N I so do you work at KFC

Gary Hawkins - 2019-11-14

Classes did me no good, same. The teaching fails in part because they use the term EMF (electromotive force) for voltage as if it were some sort of mysterious thing, they should be calling it IP, electrical pressure, from electron crowding, electrons aren't comfortable being crammed together, not unlike air molecules in a balloon. It's possible that electrons actually have no charge and instead it's simply this: When a bunch of them are crowded together, we call that negative, and when they have been sucked away, similar to a vacuum, we call that positive charge. The difference between electrons flowing in a wire because there's a crowded area and less crowded area for them to move to versus water or air in a hose trying to move from a pressurized area to one less pressurized ... is the magnetic field electrons cause when they move. That's pretty much all there is to it. But moving water, air or even light might also have a field we just haven't discovered yet. Like you guys are saying, it wasn't until I started working with actual stuff that I got it, one day, bam, it clicked, a eureka moment, and I also felt betrayed by the teachers at the same time.

So then I looked up a 7th grade school book on electricity. And as I suspected, if you know, it is written to sound somewhat ok, but if you're trying to learn, you would never get it from what they say. And that might be intentional.

vampov - 2019-11-23

I have three degrees and none in electrical engineering but I"m pretty sure touching a 3 phase circuit will help you to get a afro and a heart murmur if you are lucky and lots of sleep if you aren't.

Michael Clark - 2019-04-26

I've been a master electrician for 40 years and this is one of my favorite subjects to explain to laymen.


3 phase solves the problem of zero voltage potential and no work being done that occurs twice every cycle of single phase, with 3 phase there is always work being done because the phases overlap by 120 degrees, thereby massively increasing efficiency.


Many years ago there also was 2 phase systems where there were 4 current carrying conductors arranged in 2 sets of two that had to be paired properly, it proved to be more expensive than 3 phase, wasn't as efficient and it was a pain in the posterior so it never caught on. We had an old factory in our city that had ancient machines that ran off of a 3 phase to 2 phase motor/generator converter, I hated working on them but just my luck, I was the only person they could find that understood how the electrical parts worked. The only reason they kept them going was because they were specialized machines that couldn't be replaced.

Little tip&trick.

We use the paper masking tape (used for painting rooms) and apply it on the printerboard. After printing it can be pulled off a lot easier and the tape discarded.

To be shot? Probably. It's owner is an idiot.

Ambesh Pratik - 2019-11-23

Bill Nye is a very accomplished engineer but Mehdi is a much better teacher. Bill Nye is also trying to teach kids simpler subjects. The inability of people to look past their own biases to judge others always baffles me.

Frosty. - 2019-11-23

@Ambesh Pratik now days bill nye does the exact opposite lol


(instead of teaching science, he lies about basic biology/psychology just to sound "progressive")

Sub Pub - 2019-12-14

@Frosty. I mean, he does have established science to back him up

Blind Freddy - 2020-02-21

@Frosty. Why don't you enlighten us all on the truth about biology/psychology?

F Seemann - 2019-01-07

Just to know - in Europe you have 3 phases at home not only in industrial areas and the voltage is higher - 230V one phase and 400V 3-phase. The higher voltage got a benefit if you have a fixed power-requirement. You need with 115V a wire with the double width because of the line loss the copper wire has. One interesting history fact about transmission lines - 1882 the first transmission line was built with 2 kV DC over 57km. The efficiency was 25%. And in 1891 the first transmission line with 10kV AC over 176km was built. The efficiency was 75%. Today we use in Europe depending on the distance and economy AC transmission lines between 110kV and 1000kV. The most common used are 3 phase 400kV. Because of the weight transmission lines are out of aluminium. In comparison the weight is 55% of a comparable copper-wire with the same AC resistance and line loss.

Jaromír Anděl - 2019-10-05

@mbo191 We have only one phase. The second wire is neutral. There is no potential between neutral and ground. In the TN-C (Which is in the most older buildings) network there is only Phase and the PEN wire. PE and N are connected right in the socket. The PEN wire is grounded so it does not have any potential. In the TN-S network the PE and N are separated. But in the main switchboard those are again connected to PEN and grounded. The TN-S is more safety and allows to use the residual current device.

tuks kano - 2019-11-12

@pasparinho you can change the original 3 phase motor with a single phase motor.

Sploofy - 2019-11-21

In Sweden, all buildings get 3-phase 400V. Some older apartment buildings split that up though so the apartments only get 1 phase 230V.
My current apartment have all 3 though.

Janky Shack - 2019-11-22

Back then they didn't have transistors so no DC-DC converters, the only way to really change voltage up or down was by using transformers. Transformers can only be used in AC circuits so AC was able to attain higher voltages which greatly increased efficiency. Also on the consumer side, it was much easier and efficient to step the voltage down to safe levels with transformers.

Nico Kempe - 2019-12-21

Huh, today I learned. Thanks.

i know its just a joke (mostly lol) but don't be too hard on teachers.

they have to do it live, and they have to do it again and again. Usually to an audience that isn't super stoked to be there.

It's a very different animal

@sd samuel Explaining a concept clearly and understanding of the concept are directly proportionate. Ultimately, if the teaching uses very good methods, the understanding of the subject matter will be strong.

Sometime I used to have drop in voltage back home, so i would change numbers in every phase and voltage would comeback. Now I know what i was actually doing 😀

cokefridger - 2018-04-16

In Germany all houses have a 3 phase power supply. It is splitted in 3 single phases, but if you are any enthusiast and have for example a CNC machine or car lift in the garage, you can use all 3 phases by making a 3 phase outlet.

TunnelDragon44 - 2019-03-23

Not surprising, considering that Germany has historically been a very industrial nation.

Christian Grey - 2019-09-09
