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

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 EP, 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.

You've explained this so much better than they did at my school many years ago. The advantage of not needing the neutral wires for the combined 0 volts is definitely interesting, I wish they had explained it in this way so it might have stuck. I like your visualisation with the coaster, a simple explanation of a potentially complex subject.
@DL-kc8fc
@DL-kc8fc 2 роки тому
In fact, it's a little more complicated. The circuit is closed through a winding that does not currently have an "amplitude" (popularly speaking). However, we have other influences, such as hysteresis in the case of inductive loads. Note the case where the fan motor was rotated directly by the three-phase current from the motor. He winced and spun slowly. The fourth wire (zero) is often used in similar applications that have a "star" connection. Of course, the sum of currents or voltages in this three-phase network diagram is 0, but this does not mean the absolute cancellation of the fourth conductor. Very high voltage pylons have this conductor at the very top ...

I always wondered why doubling up 120 made 208 and not 240 but this makes perfect sense because when the phases shift 120 degrees the peaks and valleys aren’t directly over each other so you don’t get the full peak and valley of the wavelength that you would get at 180 degrees

Great video, a couple of points. 1 The input power of 3 phase motor with a current of I amp per phase and a phase to is is not 3VI but (sqr rt 3) VI 2 The reason why the motor generator set had a low efficiency was because the magnetic field was just the residual field in the laminations. Full size generator either have a rotating rectifier or slip ring to supply a dc current to the rotor.

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.

240 AC in Canada (and US) is delivered to the house with the neutral tapped from centre of a local transformer (aka split phase). Having a voltage of 203V suggests there is an apartment building transformer taking in 3 ph and and splitting off 2 phases to apartments. (apt A is red-blue, B is blue black, C is black blue, etc), nominally 208V. In my kitchen, measuring both hots gives 240AC (house), and all single phase.

LOL@mishaps. But another reason 3-phase systems got expanded a great deal in the early 1900s is because there was an efficient way to rectify the 3-phase current back to DC: the mercury cathode rectifier. These don't work too well with 1-phase AC (the arc gets extinguished on the reverse half of the cycle and is hard to reignite, whereas in a 3-phase rectifier the arc never extinguishes). Remember, there were no high-power silicon diodes back then.

7:27 It sounds like a printer motor. Because of the sine waves, and at 7:36, this is why it reminds me of "Crazy Machines - Die Erfinderwerkstatt or Warsztat Wynalazcy". It reminds me of Lasko and SMC oscillating fans with my favorite parts that match when some fan parts are different. SMC oscillating fan motor covers are my favorite when they have teardrop shaped vents in a circle, and the Lasko fan motor covers are my favorite when they have arched vents on top and horizontal vents on the bottom. The guard nuts, rectangular mountain slanted oscillating knobs, and if applicable, the "0-3-2-1" marking on the mechanical speed control on top of the motor cover unless it has a remote, which in that case, it'll be on the front of the fan (and may have a timer) are also my favorite, but it depends on what parts are intact.

@MichaelClark-uw7ex

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.

Not everyone has 3 phase power in Poland. It's common in houses, but in older flats it was common to just have one phase installation for each apartment, but it's last mile problem. Usually every building has 3 phase source available. Although 3 phase is common, there's really no big use for most of us. Only instant water heaters are a common consumer devices that use 3 phases and only high powered ones. There are many 1 or 2 phase heaters. Induction cookers are probably the main reason why most people needs 3 phase installation, but those cookers only use 2 phases anyway. I myself have pretty much an industrial installation and I have a few of big 3 phase motors. Just starting them makes you nervous. Loud and powerful.

The best reason for 3 phase is the fact that when the 3 loads are equal then the power from the system is a constant. In other words the power is NOT modulating at 60Hz like a single phase motor. Rather, the power is not modulating at all. It is a constant. This means that for a single phase motor you can hear it humming at 60Hz. But for a 3 phase motor (if it was perfectly constructed) you won't hear any hum. This means nearly no 60Hz vibration and thus the motor lasts longer. And the torque output of the motor is also a constant which induces less vibration into the load so the load lasts longer. Some math. Power is a function of the square of the voltage. Single Phase Power=SIN(alpha)^2 = SIN(2*alpha) which varies with alpha Three Phase Power=SIN(alpha)^2 + SIN(alpha+120)^2 + SIN(alpha-120)^2 = 1.5 for any alpha
