[@mikegraham7078]

Pairs of wires makes a phase. 2 wires is one pair - A-B. 3 wires makes three pairs - A-B, B-C, C-A. It's not 3 times the power because you are re-using the feeds. 10A of 3 phase is worth 17A of single phase for a given voltage. Makes a big old difference when you're wiring motors and transformers and the like. You can run 3 5A draws on 10A of 3 phase. No problem if you wire it correctly.

[@okaro6595]

Two phase is an obsolete system used in motors so they cannot call the split phase two phase.

[@mikegraham7078]

@@okaro6595 I'm not sure why your reply applies to my posting, but while I agree that two phase is pretty much obsolete, it's still out there in pockets, and it was *usually* set up with four wires so that each pair of wires was one phase. It was 90 degrees out of phase instead of 120 degrees. I also agree that split phase is not two phase. Nobody should call it two phase. You know, I should have said "pairs of hot conductors make a phase" instead of just "pairs of wires". Is that where the confusion was?

[@ollieb7394]

@@mikegraham7078 not true… for a 400/230 system we have in the UK the equivalent power for 10 amps ignoring power factor 3 phase, 10 amps = 400*sqrt3*10= 6928W 1 phase 10 amps = 230*10= 2300W

[@mikegraham7078]

@@ollieb7394 You're changing the voltage in your calculation. My point is that 3 phase of a given voltage is 1.7 times (root 3) that of single phase. So 10A of 240V three phase is the same amount of power as 17A of 240V single phase. Yes, I am rounding root 3 to 1.7 so there will be rounding error, but the statement stands as it was made. This means that if you are powering a 20HP motor with single phase (not sure why you would want to) then you would need more current, and therefore larger conductors than you would to power a 20HP motor with the same voltage of 3 phase.

[@lynncowan9864]

I haven't read all the comments - someone else may have already clarified this but the difference between phase and polarity is in the time domain. We call household current single phase because there is only one time reference. The two legs always exactly mirror each other. 3 phase is different because at the point of generation, there are three circuits, and these are isolated - each traveling in its own conductor, and they NEVER interact until they are actually doing work in a motor or other device designed for polyphase power. Each phase in three phase power is slightly behind (or ahead of) the other two phases in terms of when their voltage peaks. The peak difference between any two phases being 208V in North America. This is why single phase gives 240V across the two legs, but 3 phase only yields 208 - the two legs are not in phase. In single phase applications, the two legs are 100% in phase - they're just opposite polarity, so the difference between them is greater.

Open up a car alternator. If you look closely at the stator setup in the alternator, you will see it is made up of three separate windings/stators. The three windings/stators produces three phase current as they are set at 120° apart from each other. What turns the three phase current from AC to DC is the diode trio the stators are connected to. Car's used to use generators. The reason alternators are used instead of generators is because alternators are more efficient, smaller and can be controlled easier than generators.

I think you should talk about what it is, how it’s created, it’s usage, and the fact that it isn’t obligatory for an electrical system to work but very useful for using different voltage on the same grid without a transformer. (Sorry if i didn’t use all the correct technical terms, I have to translate it from French).

Good video Dustin. This also happens in reverse even when we don't want it to with three phase. I work on a lot of pump Jacks for oilfield and when they are on drives and the weights are out of balance and crest over the peak and they are weight heavy they start pushing the motor and the motor starts generating voltage back into the drive. This has to either be fixed by balancing the weights properly or a dynamic breaking resistor put in place to catch the motor generated voltage and it shunts it and turns it into heat

When I try to explain the wild leg to people they look at me like they just tasted shit!! but Dustin Explains it perfect here. phase to phase you will get a consistent voltage across all 3 of the legs but the stinger/wild leg has a neutral in there that can get you into trouble if you try to put a single pole breaker in, if its a dual pole breaker or 3 phase breaker line to line is always going to be the same, you have to know the difference between the 3 lines and a neutral(grounded conductor) in a stinger/wild leg panel there will always be one breaker out of every 3 that is 208 to ground/neutral. watch the video I linked to. Dustin explains it perfectly. Lots of guys who dont get it will put a breaker in that open spot every 3 breakers to run a light or an outlet without realizing that that particular bus bar is 208 to ground and start frying shit. had an IT guy who thought he could wire stuff at a property I worked on, kept frying stuff but come to find out he was using the stinger leg in the panel to tie things into. he never bothered to check voltages, he just hammered a breaker in and ran his cable and wondered why the magic smoke was always coming out if his equipment,

[@businjay]

@@joshuahatridge3833 You also need to make sure you are checking phase voltages properly. 1-2, 2-3, 3-1 all those should be 208 or 240, where it starts getting interesting is when you go 1-n 2-n-3-n, will all be 120 except one of them if it is a 4 wire setup depending on which is the stinger/wild which will be 208.

If you used three separate generators, trying to sync the phases from three different generators to be 120 out from each other, nearly impossible…

[@iGameriOS]

Modern phase splitting involves solid state electronics, you take the 1 phase AC, rectify (convert) to DC, then using 6 MOSFETs with a timing circuit gate the MOSFETs on and off in a way that makes stepped DC that looks like AC. This is the same method used for AC car outlets only with less MOSFETs. The old method involves using capacitors to shift the current vector, its complicated to explain without getting into vector charts. This is method has been almost entirely replaced by solid state systems. A third method would be to used a motor-generator. The motor side is a 1 phase machine, the generator side is 3 phase. This also works for DC to AC conversion without using solid state equipment. This method is also used to adjust frequency for special equipment, by changing the number of magnetic poles on the generator you change the frequency while maintaining the same speed. This method is usually found in naval applications or old equipment that required very clean DC voltage that was hard to rectify before modern solid state systems.

Great simple explanation. Got the answer I was looking for 7 minutes in.

[@alz582]

Great simple explanation, couple things I wish you would've provided for additional background: - The excitation required for the rotor (shaft) on a generator to induce voltage on the stator (outside coils) as it spins. - The role magnets play in transformers. I'd be carful telling people that electricity is transformed onto the load side across an air gap. Rather the movement of the current through the primary windings as it wraps around a magnet induces a current on the magnet, which through the ratio of the coils on the low side wrapped around the same magnet in comparison to the high side creates the inverse of voltage/current output on the secondary windings. Not trying to puff my chest or anything like that. Just a bit of a nerd for electricity.

I'm glad you mentioned about the 'color' of the wires. it's infuriating that some people struggle with an inability to distinguish between a symbol (colour of the metal sleeve) and the thing for which it stands (the electrical current in the system).

[@jesusJDCS]

I worked with a master electrician and his name was also Dustin 🤣🤣 and looked like you and he was the smartest electrician I ever met he loved the theory or electricity and showed it.

[@ifrpilota]

Sinewave: although your magnet explanation is right I would have a comment. The sinewave is not only a graphical presentation of the voltage and/or amperage but this sinewave actually present in the wire (conductor). Start with the zero-crossing (it means there is no voltage nor amperage present in the wire - at all. Then the voltage start to grow until it peaks at 120V then it drops back to 0 and it starts over the same thing just the opposite direction. Imagen a battery connected to two wires you have + and - but 60 times in one second, you flip the battery between the wires. That would be a square-wave. just because the voltage increases and decreases between flipping you get the sine-wave. Love your presentation.

[@I_am_Deliverer]

Wow so well explained. I got lost on plant electrics at college when we jumped to 3 phase!

[@mikefixac]

I'm just getting off on Dustin's LED computer screen. I'd love to know how it's done. First-class demo by a first-class teacher. Great job.

[@sealstech8087]

I think what threw me off for a while was a rendering of single phase generation has 2 wires and I always equated that to 1 phase that we would split with a neutral but that still one phase loop was feeding a home. That made my mind warp when I then considered that electricity is generated in polyphase and one phase is actually off set loop a/b b/c c/a. I might be stupid but I think the visual models create a misconception that is hard for a student to explain. Visualizing polyphase still bends my mind a little to imagine the way the generator is wound. The transformers are what truly make it marvelous. I love seeing the mains for a drilling platform or pump power. I swear I saw a bank of transformers that had every phase connected to everywhere. Primary and secondary side with little resistor looking things between h1 and h2. They had star delta high leg and a split single service drop wired on one pole going in different directions/conduits. I also noticed out in the boonies it seems every 6th or so pole has all 3 phases co bonded to the neutral. I thought they were isolated and tapped for a future transformer but the insulators are wrong, there would be no place for a fuse without a lot of changes to look like the rest.

Got to had it to you, you explained that better than any teacher I have had.

Good job explaining. More of these quick lessons are a definite plus to the channel ! PS, I think the capacitor at the end messes people up, haha. Maybe explaining the reactance chart(Eli and iceman) and a 30 degree shift between delta and eye connections for next video ? Much love man, you help me a lot !

That actually made sense, you're a good teacher, I have ADD and a lot of the time I have to watch something like umpteen times before it makes sense. However I have always wondered how do you tell if your house is three phase or single phase ?

[@david-tracy]

hey man youre a good teacher - props… just wanted to let u know

[@christophermeyer6414]

This video is awesome! I never understood how 3 phase worked, until know! Just think of it like a two cylinder engine vs. a 6 cylinder engine. Single phase being the 2 cylinder and 3 phase being the 6 cylinder engine.(just my perspective) Thank you!👍🙂

[@tylerskidmore507]

I'm so glad you explain things so nicely, I finally get it!

[@ifrpilota]

Absolutely nice presentation I enjoyed it as a master electrician who worked with electricity since 8 years old. If I may have some comments. The term "Single Phase" is completely wrong in the industry and persons like you should be correcting it. Let me explain why. Single or one phase is really the black wire and the white. The white wire does the same thing but it is grounded so when you touch it it will not shock you. That is only a safety consideration and has nothing to with current flow. If you take away the ground from the white wire, it will become a black wire and you have now the single phase circuit. Do you agree? Now what the industry calls a single phase circuit, it is really a 2 phase circuit, because the red is exactly the opposite of the black. In 2 phase system the white wire (neutral) is only carrying the current differences between the two phases, as you explained perfectly. Nice work from your end.

[@auletjohnast03638]

SINGLE PHASE VS THREE PHASE: SINGLE PHASE HAS ONE LEG TO STAND ON AND THREE PHASE HAS THREE LEGS TO STAND ON.

Question: I already have 3 phase at my property. I need to run power to a shop. Do I pull single phase and install a box for my current needs, or pull 3 phase and install the associated panels/wiring? Pros, cons?

[@sumilidero]

Well the problem is, that he got that 3ph gen wrong. its not 3 cam-like magnets in line on the shaft. Its one big magnet on the shaft, and 3 windings spaced 120 deg in the stator. When magnet rotates, it reaches windings one after another.

[@traditionaltools5080]

@@sumilidero it's almost all wrong. He also goes into a huge explanation using 120 degrees for sine waves and mechanical degrees. The problem is poles are mechanically 180 degrees apart. He's confusing the two. Among other things.

[@sumilidero]

@@traditionaltools5080 Thats unfortunate video, also he wasnt confident about what he was talking, you could immediately see he had no idea about that. Need some industrial-experience, not only plug changing ;)

[@harrymiller513]

@@sumilidero the magnets in a generator are south and north poles in one. Meaning each magnet has a north and south pole. So they are 180 degrees displaced. At one instance the north pole crosses a winding while at the same moment the south pole crosses a winding that is opposite. The three circuits generated are 120 degrees to each other by the physical placement of the other windings..
