After 4+ years in school and 3+ years working in the industry, this video explains three phase power in just under 8 minutes better than any of my teachers and coworkers ever have.
KISS principle,- keep it simple stupid, I think when we get away from that ,everything goes to hell. Everyone/ Alot of folks have to try to impress others so they can feel better about themselves at the moment or end of the day and when they do that, they confuse themselves along with everyone else. Face it, humans are wonderfully flawed, we shouldn't take ourselves so seriously. As the great philosopher, Bugs Bunny said: ( you can't take life to seriously, your not going to make it out alive anyway). Uh, yeah ok valid point there...
Yes, but I believe the animation is incorrect. The magnetic field around the magnet in the generator is actually toroidal in shape (like a tall, stretched out doughnut) with the North and South poles at the red and blue ends of the magnet, NOT THE SIDES OF THE MAGNET. Both sides of the magnetic field are of the same neutral polarity. Also, the current is induced in the armature coils when flux lines CROSS the coil, NOT when they run ALONG THE COIL as animated. Therefore the animation is 90 degrees out of phase with reality. This can be confusing for new students..
Agreed. Many are good at what they do but they can't teach - as I've discovered. It's all about being able to put yourself in the students' place. That was done here.
Am a maintenance electrician, meaning that I was taught all this in further education...if only there were this kind of tutorials back in the 1980's...I've learnt more in 7 minutes here than I did in 3 years back in the day...well done guys. Big old thumbs up and another subsciber
I am not an electrician. But I used to work as an electrician’s helper. I never understood the differences when they would mention 3 phase motors and similar terms. This is the best explanation I’ve ever seen. Thanks!
The Visual graphics along with the theory have made it possible to learn such a complex subject so easily. This is how we should be taught in schools. 👍👍
Completely agree it’s taken many years but now 3 phase power is not a mystery to me anymore great tutorial I just love being educated it’s more power to me if Ull excuse the pun
@@mikeymcmikeface5599 Mikey... Your typical residential home gets two 120 volt feeds, a neutral, and a ground. Your typical residential home uses single-phase power. Three-phase power is reserved for businesses/commercial use, who require that type of power. While I don't know where you're from... I'm not certain why you would be in the dark about that. Hope that helps you out.
I am a former licensed aircraft maintenance engineer ( electrical and instrument ) and this is the best introduction to 3 phase that I have ever come across. Wish it had been around during my training.
I was a residential electrician for a number of years. Never had to worry with 3 phase, and sorry to say even after studying the code book intensely I never had a real good understanding of it. Long time coming. Super thanks!
I’ve been in electronics for most of my 65 year life. This is a good explanation. I see people who mistakenly say that D.C. isn’t used for houses because it doesn’t travel as far. Not correct! A.C. was chosen because it can easily be boosted to high voltage, which can travel on smaller wires, then transformed to lower, safer, voltages when it arrives in a neighborhood. D.C. cannot be changed in voltage by transformers. Interestingly they are now using high voltage D.C. to ship power in some places because it has less loss. With the advent of modern electronics we can now change D.C. up and down in voltage economically. It remains to be seen if this will be the wave of the future however.
I have had 3 phase power explained to me multiple times by licensed electricians, and this video was the first time that someone explained how the shape of the rotating EM field correlates to the angle with which the phase wires are arranged around it, and why. Thank you.
Mate, you are saving millions of students with your magnificent videos. I am watching you videos for 2 days straight already as preperation for my upcoming bachelor exam and you cant imagine how grateful i am for being able to see your videos. I think i learned more about electrical enginnering in the last 2 days watching your content than i learned in the last 3 years of studying at university HAHAHAHA So thank you very much!!
I'm an engineer working in manufacturing and work with electrical contractors a lot. This greatly helped clear up some concepts for me! The Engineering Mindset channel is awesome! I'm watching your other videos kinda binge watching. Great job explaining things in layman's terms!
Electricity has always been a bit of a mystery to me. This video has made understanding the basics of electricity easy to digest. A class mate from my youth working for NV Energy tried explaining the basics to me and he sounded like a boring high school teacher. His motivation may have been because he’s the type of guy that wouldn’t want what he does for a living to sound to simple. Which it isn’t regardless of the explanation. Thanks for making it easier to grasp.
The first time I heard of 3 phase power was when I worked for the carnival. The generators they use are 3 phase. My supervisor gave me a basic understanding but this video helped me a little bit more.
While several previous viewers have commented on technical corrections I thought the explanation (concept is what we're going for) was brilliantly portrayed. Considering the target audience (non-engineer non-electrician type people like me), I would offer an enthusiastic two thumbs up! Nice job!
Just discovered this guy, i am watching the tenth video, my eyes are in tears because i am tired from a long day, but i can't stop watching another and another video from him. I am a big consumer of youtube videos like this, and after years of self learning, i can guarantee you that he has the best videos in engeeniring domain on youtube.Thank you my friend, in the name of everybody like me, for your work, and dedication to this! You are very good in what you do here, and you are helping a lot of peoples who want to to learn!!!
i’m currently in a lineman class and they don’t really explain why there’s three phases or what they do just how to work with them, this is the only video i’ve found that actually explains it in a way i understand, thank you!
Dude thank you so much. We had electrical engineering subject for a year and I never understood how 3 phase appliances work. Now when I am starting my own factory after all these years, I had to understand 3 phase power to understand functioning of my powerful induction motors. You did a greatr job! Thank you so much man 🙏
Until finding this video I wasted more than a few hours reading (books with lots of equations, web articles that were sloppily written) but without really understanding (or remembering). This video is brilliant. Am now subscribing to this series (just out of curiosity ... not my vocation... but seems a good way to learn). Thank you.
I honestly went to school for Instrumentation and Process Control. If your videos were played in a classroom setting, the institution could have crammed three semesters into two. Excellent video!
This video was amazing. For years I've wondered why why when we have a powercut my neighbour keeps his power, or visa versa. Obviously I knew about phases but the WHY is brilliant to learn, thanks man.
I am a chemical engineer working with motors and electrical stuff for projects, I'm not messing with anything but I need to know how everything works. Thank you so much for putting these out. You are an invaluable resource!
Hi I have degree in elec engineering, but brushing up to take my masters in hvac. I found your video here and if seems like you explained it just fine. Someone said magnet not needed but it is how the armature keeps spinning as one side attracts and the other repels, keeping it spinning. That's basically how any turbine works. Just know that it keeps the voltage from dipping too low. Definitely need the magnets 🧲 Also just think of a sinewave. That's your voltage and it crosses 0v twice a cycle. Is ok when using s lamp, because it cycles 60 times a second. Not noticeable. But some high quality equipment can't be having it..that's why 3 phase not single phase. 😅
A whole freaking semester in AC circuit Analysis and I couldn't understand that three phase power concept because my professor......well what's a nice way to put it? Let's just say stupid at explaining for now. 3 mns in the video, already understand how all 3 phases work. I swear I should be paying the internet for tuition. Thanks

lierox9 That's why teachers are supposed to be resourceful, meaning find the best way to convey knowledge to your students. If my teacher noticed we could not understand this, he could have showed us this video. Don't just show up to class and teach. PREPARE before u stand in front of a bunch of people so you don't make a fool of yourself.
The problem with teachers is they work for the government so they arent held accountable for their performance the way people in the private sector are. In other words they get paid exactly the same whether you fail or pass so they have no motivation to try hard. Blame liberal policies and vote republican if you want change.
I start a new job, I worked residential electricity for about 18 months, going to start in a factory as a maintenance person. This was a good summary on what I needed to understand, thanks for explaining it!
I just started at a factory in maintenance and I needed a better understanding of three phase so I came here and I got it now! I worked residential too! Good luck to you!
I've installed a 3-phase toaster in the kitchen for my impatient wife. It now toasts three times as fast, but the pop- up feature has cratered my ceiling.
northerniltree lol well I have seen three grills but all heaters init after single phase but only uses be three phase to keep cost of wire down run from dreaker to grill
Objection! The pop-up feature works on a spring and an electro magnet holds the spring down until the timer releases it, so u have to add three more springs in order to shoot your ceiling.
Fantastic....I've been wiring single phase household/commercial wiring since I was a kid taught by my father who was a contractor. I've always understood the how to wire stuff...but never the science/mechanics behind the why! Now I work in an industrial setting (CNC machine shop) and work with 3 phase machines all the time....yet I had no understanding of 3 phase power other than the explanation that "its more powerful and cheaper". Well that doesn't cut it for a person that likes to understand the reasoning behind how something works! I've watched lots of videos trying to make sense of it....FINALLY....someone has broken it down to the science/mechanics and I understand how 3 phase works. This allows me to reason why we use it and why it performs better in its intended application! I can't thank you enough!!
Oh. My. God. I have had so many people try to explain this and fail (I'm not sure they really understood it themselves). Your explanation and animations took far less time and made it easily understandable. Well done, Sir!
Never, ever commented on any video before but this must be the best instructional 8 minutes I've spent. Restoring on old French farmhouse with a three phase well pump and now I understand it. Thank you seems so inadequate.
This is, by far the best illustration I have seen on 3 phase power. It also does a great job expla8ning AC power. The dashes illustrating electrons moving are slow for the sake of the graphics, however they really move a few hundred miles out and back each cycle. Excellent video!
I always wanted to study electricity. I've worn many hats over the years and at 42, I'm finally able to take the time and dive in. THANK YOU for this video and audio descriptions.
Solid explanation, and clear animation. I have a gripe about the way the magnet on the rotor is presented. The North and South poles are not the sides, they are at the Top and Bottom. The max voltage is when the magnetic lines of force are cutting across the conductor at max rate, and that is on the bristly bit, not the loopy bit.
I thought all my electrical education had flown out the window when I saw that bit! However, I was attracted to the inductions I made from the current knowledge I was taught, and wasn't phased at all after a bit of reflection on my capacity to remain charged with what I learned.
Bro, you are just more than great you didn't know how much your electricity series has helped me to get out the chaos made by my illiterate physics teacher A big thank you, may you get lot of prosperity in your life 😀😀
Thanks. Teacher never actually explains what anything is used for or why. Pretty much just learn how to solve mathematical puzzles with no understanding of what their use is. Really appreciate this video
That’s why building that use voltage sensitive equipment, have a Uninterrupted power system to provide constant power to their equipment through a battery bank. Simple explanation to a complex system.
Great spatial and mechanical explanation of AC power generation and flow. This confirms how I thought it worked for many years, but could never get any kind of clear explanation from some of my electrican friends. I began to suspect they probably didn't really understand it themselves. I guess you can spend years pulling wires and not need to know this stuff. I absolutely love your videos! Thanks!
@Karen Fiedler I call that the "Waterboy" condition. In that movie, Adam Sandler's character was constantly involved in football games, but he never learned how to play, because it wasn't necessary for his particular job.
Finally, someone who actually explains how the 3 phases are finally connected and used in homes and factories. There are lots of sources of what 3 phase electricity is, but rarely talk about how the 3 phases are divided into single phases for home use or kept as a 3 phase for large equipment use.
The display in the manner The Engineering Mindset only used that display only to not confuse people like me. He did an excellent job explaing the different phases, he was not trying to show how the magnet works.
Most homes, at least in America, get two phases. We have large appliances like electric ovens and air conditioning units that work on 220vac and require two phases.
@@hankeisenstein272 No. They get one phase that goes through a local transformer which is center-tapped to give them 2x110V. It's still just one phase.
Well presented using modern techniques. It reminded me of the financial benefit of using 3-phase for power transmission, because it actually minimises the amount of cable as long as the load is balanced across the phases, compared with delivering the same amount of energy via single phase. This point was made quite early by one of my old lecturers in the past. High voltage/3 phase is better for your cash flow!
This is the best video i have seen on this topic...its so perfect, short, crisp yet very powerful. KEEP UP THE GOOD WORK MAN!! YOU ARE MAKING A STUDENTS LIFE FAR EASIER...
Dude what a G. I’ve been struggling with electricity for years and I found all teachers just confused me. Just watched this video now and guess what… it all makes sense now. Great work man keep it up👌🏼
Nice explanation and animation. Thanks. One step further: The smart thing is that it does not use 6 wires but 3 wires or 3 Phase wires and a Neutral wire. This allows to reduce the amount of copper needed to transport electricity at a certain voltage. The Neutral wire also allows to make 2 voltages available, depending on the wires used. In Europe, this is 230 V between Phase and Neutral and 400 V between Phases. There is no current flowing through the Neutral wire when all three phases have the same load.
A good video, but I have a tiny correction. I work at a power company and we want all our customers to get three phases to their house, even if it's small. The reason is that it's easier to get an even load on three phases of the transformer when everyone gets all three phases. In areas with a lot of old houses that only have one we often see that 1 or 2 phases are almost maxed out while the third if far from maximum. But as I said, it's just a tiny correction in a good video :)
@Sphaa How does this work in reality? Are my different rooms connected to different phases? Or is one appartment on one phase and the next one on in different one?
I don't know where you work in the power company but as an electrician in United States I can tell you that 99% of all residential houses have single phase 3 wire services. ( 2 ungrounded and 1 grounded conductor)
@@shanejknox Those two ungrounded lines are actually two phases that are 180 degrees out of sync. That's why you get 240 between them. If they were the same phase there wouldn't be way to run your 240 stuff.
@@dub23handb You are correct. But it's still called a single phase service. The reason for this is because even on a 2 pole circuit (240v) with no neutral there is still only one path for current flow hence the term "single" phase. There's no such thing as a two-phase service. But your comment has nothing to do with what I said, three phase as a branch circuit is only utilized for 3-phase motor loads. not lighting as this video suggests. And residential buildings in the United States typically do not have 3-phase services
Did this at college 40 years ago but rarely ever came across it in my day-to-day job (only the occasional 'beware 440v' warmings). Didn't really need a refresher but this was a clear & concise vid (thanks YT algorithm).
I learned about 3P electricity on one of the my first jobs I ever held and was able to grasp the concept pretty well. BUT was not able to really invision what was going on on how the generators that I worked with did produce the 3P electic. Over the years I continued learning and ultimatly was able to totally understand the workings. The graphics you produced are fantastic and really simplifies on how 3P electricity works. Great video.
I'm applying for an engineering position where they (presumably) use induction motors to power a conveyor belt system. I watched a great video on induction motors themselves, but I failed to understand why 3 phases were used. The moment I saw your diagram with one phase, and you had explained the positive/negative/neutral sections of the magnetic field, I instantly realized why 3 phases would be used, and got a little excited. I can't express my appreciation to you for helping me improve my chances at becoming a better engineer and worker.
My dad got a degree in electrical engineering, so I grew up helping him wire relatives houses. It took me a long time to realize that everyone wasn't pretty familiar with amperage, voltage and phases. Now thanks to the internet, anyone can gain an understanding of it.
Excellent presentation. Wish they had explained it to us in engineering school like you explained it in your video. Also liked your comment that you can add more phases but it would be inpractible and costly to implement. Thanks for a good visual explanation.
also, while adding up to 6 phase power is a basic linear gain, going to 12, 24 or 48 phases doesn't produce the same gain, it's much less per added phase
I want to be an electrician but was nervous because it all seemed so mysterious and confusing. I love these videos because they make understanding electricity easy :)
We have 3 phases in to almost every house in Sweden and it's about the same in neighbouring countries. This is really nice to have when charging a car since I can use less amps from each phase but still charge it fairly fast.
I'm a bit puzzled - the bar magnet markings and magnetic field strength seem to be opposite of normal convention. Typically the red area would be marked "N" and blue "S" and the maximum magnetic flux is at the end of the poles, not in between them, and there would be arrows showing the field going from N to S (which helps determine which way the current flows in the stator windings). The flux lines coming out of the end of the poles would also be depicted as intersecting the stator windings and thus the current is maximum when a pole is directly opposite a stator winding, not when it is in between them. One very good thing about the animation is that it explains well the light going on and off, which is a 120 times a second with 60HZ AC. It might also be useful to explain that a two pole rotor like this one would have to spin at 3600 RPM to get 60HZ, so typically they would be more rounded to keep from flying apart. It also appears the generator depicted is an induction type generator which isn't used much (yet) to power communities.
It seems the video is showing *current*, not voltage. Current is induced by a change in magentic flux, which is zero at the poles and higest between poles.
This is so much better and easier to understand than any technical manual, or Wikipedia for that matter. The generator diagram at the beginning is the most important part of understanding the principal of the phases. Well done video.
Good video, but you have made a slight mistake. The output voltage is 0 when the magnetic field through the coil is at its strongest, and the output voltage is at its peak when the magnetic field through the coil is 0. This is because the induced EMF depends on the derivative of the magnetic flux, with respect to time, and the magnetic flux is sinusoidal.
Not really a mistake, the video seems aimed at dummies like me. I understand this video enough to understand the basics. While i'm sure your right in what you say, you lost me in 1 paragraph.
It's faraday's law. The induced emf is proportional to the rate of change of flux. The rate of change of flux is highest in a generator when the flux linkage is lowest. e = BANwsin(wt)
Incorrect JT. The rate of change is the derivative. The derivative of a sine way is 0 when at max or min; it is max/min when the original signal is at 0.
So basically the lamp will light in according to a cosine wave. However, he mentioned Power, and you're talking about Voltage. We multiply Current with Voltage to get Power, so that may change things up a bit. I'm not sure, but there seems to be a discrepancy in your argument.
Great video but one more minor point, it's not the "speed" of elections that increases and decreases but their intensity, their number/ strength. Electrons always follow at a constant rate based on the speed of light.
Hey there, great video. I would just like to point out that the biggest reason we use 3 phases comes down to more than just what is reasonable for most budgets. 3 balanced phases have a very important property where the sum of their instantaneous power output stays constant when the loads are the same. This apparently makes transmission of power easier, but also means a 3 phase motor will be able to receive a constant instantaneous power from the electrical grid. With less than 3 phases that power is subject to intense oscillation and even dips below zero at times.
You should do a presentation on how an isolation line filter or isolation transformer works. I've heard of techs using them to float the ground of test equipment while using an oscilloscope. I'm not sure I'm fully wrapping my head around this. I love your visual aid and diagrams, they really make sense.
1. Very nice animations. A picture is worth a thousand words, and an animation is even better, and I appreciate that it takes a lot of work. 2. You say that as the magnetic field moves through the coils, the electrons go faster and slower. I thought the voltage increased and decreased while the speed of the electrons stayed the same. 3. Regarding complaints about your dialect. English has many dialects and there is no "correct" one. Interesting note: most languages don't have the "th" phoneme of English. That's why they often say "zis" and "zat". Even some English dialects say "dis" and "dat". But I think many of us aren't used to the dialect that says, "one, two, free", or "froo" for "through", or "togevva" for "together". It gets easier to understand as you get used to it.
@@jovetj - You are correct that the electrons always move at the same speed. However, what changes are the number of electrons flowing around in the circuit, not how far they go. Current in a circuit is a measure of how many electrons are flowing past a certain point in the circuit each second. That's what an ampere (amp) is by definition.
@@jovetj - Voltage and current are directly related. As the induced voltage in the windings goes up and down the amount the current flowing in the winding and through the load also goes up and down. And the electrons always move at the same speed regardless of the amount of current. I'm not sure what you meant when you said, "they just don't move as far".
I think this video gives a pretty good intro into three-phase and some of its uses without getting into the nitty gritty that confuses people. With that said, I think adding a bit more on delta/wye load/source configurations, transmission lines, and a brief mentioning of the frequency domain could’ve helped bridge the gap between the math and the theory
Good video! Though I was missing one aspect of 3-phase electricity and that is the voltage part. In Western Europe, most 1-phase sockets deliver ~230V AC, but 3-phase appliances work at ~400V. The higher voltage comes from the time difference between phases themselves. That was a subject I found difficult to grasp when I they tought me.
It isn't the 'intensity' of he magnetic field that causes current to flow. It is the rate of change of the magnetic field across a coil. A strong, but unvarying, magnetic field will cause not current to flow. Actually, what the varying magnetic really produces in a coil of wire is a VOLTAGE. If the coil is connected to an open circuit, a varying magnetic field will produce a varying voltage, but there will be no current. If the circuit is connected to a load (a resistance) current will flow.
The rate of change in a revolving magnetic field is also dictated by the strength of the magnet though... A stronger magnet produces a greater difference in the electric field as it moves
Only older houses or apartments use single phase. At least in northern Europe like Germany, Austria and the Netherlands the normal houses have three phases into the house to use saws, shredders, welding equipment (these of course in rather rural areas, welding in your living room at the 30th floor doesnt't make THAT sense...), charging your car with 22kW (or even the Renault Zoe with 43kW), use direct water heaters and so on. 3x63A is normal, 3x50A is the new standard, underdeveloped regions in Germany like bavaria have only 1x35A for the whole house which is fairly enough if you heat with oil or wood and cook with gas.
3x65A seems excessive for a normal residential single family house. In Finland most are in 3x25A range. Price for 65A feed is quite a lot more than for 25A. Even for a car charging you do not need to fill it in 45 minutes, as you usually would do it overnight. And heating by direct electricity is not efficient without sometype of heatpump.

Yes, but I believe the animation is incorrect. The magnetic field around the magnet in the generator is actually toroidal in shape (like a tall, stretched out doughnut) with the North and South poles at the red and blue ends of the magnet, NOT THE SIDES OF THE MAGNET. Both sides of the magnetic field are of the same neutral polarity. Also, the current is induced in the armature coils when flux lines CROSS the coil, NOT when they run ALONG THE COIL as animated.

I’ve been in electronics for most of my 65 year life. This is a good explanation. I see people who mistakenly say that D.C. isn’t used for houses because it doesn’t travel as far. Not correct! A.C. was chosen because it can easily be boosted to high voltage, which can travel on smaller wires, then transformed to lower, safer, voltages when it arrives in a neighborhood. D.C. cannot be changed in voltage by transformers. Interestingly they are now using high voltage D.C. to ship power in some places because it has less loss. With the advent of modern electronics we can now change D.C. up and down in voltage economically. It remains to be seen if this will be the wave of the future however.
no 'wave' if it is DC......LOL -Cheers

Electricity has always been a bit of a mystery to me. This video has made understanding the basics of electricity easy to digest. A class mate from my youth working for NV Energy tried explaining the basics to me and he sounded like a boring high school teacher. His motivation may have been because he’s the type of guy that wouldn’t want what he does for a living to sound to simple. Which it isn’t regardless of the explanation.
Thanks for making it easier to grasp.

The first time I heard of 3 phase power was when I worked for the carnival. The generators they use are 3 phase. My supervisor gave me a basic understanding but this video helped me a little bit more.
Fellow Carnie here... and used to work on the 250KW CAT generators and connecting the various rides. Learned alot about 3P electric from that job. :)

@@EngineeringMindset thanks! Will do
Hi I have degree in elec engineering, but brushing up to take my masters in hvac. I found your video here and if seems like you explained it just fine. Someone said magnet not needed but it is how the armature keeps spinning as one side attracts and the other repels, keeping it spinning. That's basically how any turbine works. Just know that it keeps the voltage from dipping too low. Definitely need the magnets 🧲 Also just think of a sinewave. That's your voltage and it crosses 0v twice a cycle. Is ok when using s lamp, because it cycles 60 times a second. Not noticeable. But some high quality equipment can't be having it..that's why 3 phase not single phase. 😅
A whole freaking semester in AC circuit Analysis and I couldn't understand that three phase power concept because my professor......well what's a nice way to put it? Let's just say stupid at explaining for now. 3 mns in the video, already understand how all 3 phases work. I swear I should be paying the internet for tuition. Thanks

To be fair explaining it without those lovely animations would be near impossible!
lierox9 That's why teachers are supposed to be resourceful, meaning find the best way to convey knowledge to your students. If my teacher noticed we could not understand this, he could have showed us this video. Don't just show up to class and teach. PREPARE before u stand in front of a bunch of people so you don't make a fool of yourself.
The problem with teachers is they work for the government so they arent held accountable for their performance the way people in the private sector are. In other words they get paid exactly the same whether you fail or pass so they have no motivation to try hard. Blame liberal policies and vote republican if you want change.

I've installed a 3-phase toaster in the kitchen for my impatient wife. It now toasts three times as fast, but the pop- up feature has cratered my ceiling.
northerniltree lol well I have seen three grills but all heaters init after single phase but only uses be three phase to keep cost of wire down run from dreaker to grill
Objection! The pop-up feature works on a spring and an electro magnet holds the spring down until the timer releases it, so u have to add three more springs in order to shoot your ceiling.
Add butter to the impact area and the job is complete
@@nikitahoekstra876 Yes, great thinking, that is correct! ^_^
The pop-up is spring loaded.....how would more power entering the toaster affect a spring-powered feature 😂
Fantastic....I've been wiring single phase household/commercial wiring since I was a kid taught by my father who was a contractor. I've always understood the how to wire stuff...but never the science/mechanics behind the why! Now I work in an industrial setting (CNC machine shop) and work with 3 phase machines all the time....yet I had no understanding of 3 phase power other than the explanation that "its more powerful and cheaper". Well that doesn't cut it for a person that likes to understand the reasoning behind how something works! I've watched lots of videos trying to make sense of it....FINALLY....someone has broken it down to the science/mechanics and I understand how 3 phase works.

Solid explanation, and clear animation.
I have a gripe about the way the magnet on the rotor is presented. The North and South poles are not the sides, they are at the Top and Bottom. The max voltage is when the magnetic lines of force are cutting across the conductor at max rate, and that is on the bristly bit, not the loopy bit.
When engineers try to explain physics, it can get a little.. creative.
Came here to find this exact comment. Thanks
I thought all my electrical education had flown out the window when I saw that bit!
However, I was attracted to the inductions I made from the current knowledge I was taught, and wasn't phased at all after a bit of reflection on my capacity to remain charged with what I learned.

Finally, someone who actually explains how the 3 phases are finally connected and used in homes and factories. There are lots of sources of what 3 phase electricity is, but rarely talk about how the 3 phases are divided into single phases for home use or kept as a 3 phase for large equipment use.
Glad you enjoyed it. There are many different ways to connect houses and buildings but the ones shown were a simplified overview to help understand.
The display in the manner The Engineering Mindset only used that display only to not confuse people like me. He did an excellent job explaing the different phases, he was not trying to show how the magnet works.
Most homes, at least in America, get two phases. We have large appliances like electric ovens and air conditioning units that work on 220vac and require two phases.
220vac split phase. For 120vac devices. L1,L2 = 120vac to neutral. 220vac across L1 and L2. L1 and L2 are 180 phase angle.
@@hankeisenstein272 No. They get one phase that goes through a local transformer which is center-tapped to give them 2x110V. It's still just one phase.

Well presented using modern techniques. It reminded me of the financial benefit of using 3-phase for power transmission, because it actually minimises the amount of cable as long as the load is balanced across the phases, compared with delivering the same amount of energy via single phase. This point was made quite early by one of my old lecturers in the past. High voltage/3 phase is better for your cash flow!

Nice explanation and animation. Thanks. One step further: The smart thing is that it does not use 6 wires but 3 wires or 3 Phase wires and a Neutral wire. This allows to reduce the amount of copper needed to transport electricity at a certain voltage. The Neutral wire also allows to make 2 voltages available, depending on the wires used. In Europe, this is 230 V between Phase and Neutral and 400 V between Phases. There is no current flowing through the Neutral wire when all three phases have the same load.
False, a neutral wire still is a current carrying conductor, it only serves as a return path to the source in an AC circuit
@@MonkeeyMan35 the neutral wire carries current when phases do not carry the same load indeed.
@@MonkeeyMan35 Neutrals are for single phasic loads. in a true 3-phase load, there is no neutral.

A good video, but I have a tiny correction. I work at a power company and we want all our customers to get three phases to their house, even if it's small. The reason is that it's easier to get an even load on three phases of the transformer when everyone gets all three phases. In areas with a lot of old houses that only have one we often see that 1 or 2 phases are almost maxed out while the third if far from maximum. But as I said, it's just a tiny correction in a good video :)
Very good point. If I got your idea, you are talking about "phase balance"
@Sphaa How does this work in reality? Are my different rooms connected to different phases? Or is one appartment on one phase and the next one on in different one?
I don't know where you work in the power company but as an electrician in United States I can tell you that 99% of all residential houses have single phase 3 wire services. ( 2 ungrounded and 1 grounded conductor)
@@shanejknox Those two ungrounded lines are actually two phases that are 180 degrees out of sync. That's why you get 240 between them. If they were the same phase there wouldn't be way to run your 240 stuff.
@@dub23handb
You are correct. But it's still called a single phase service. The reason for this is because even on a 2 pole circuit (240v) with no neutral there is still only one path for current flow hence the term "single" phase. There's no such thing as a two-phase service.
But your comment has nothing to do with what I said, three phase as a branch circuit is only utilized for 3-phase motor loads. not lighting as this video suggests. And residential buildings in the United States typically do not have 3-phase services

I'm a bit puzzled - the bar magnet markings and magnetic field strength seem to be opposite of normal convention. Typically the red area would be marked "N" and blue "S" and the maximum magnetic flux is at the end of the poles, not in between them, and there would be arrows showing the field going from N to S (which helps determine which way the current flows in the stator windings). The flux lines coming out of the end of the poles would also be depicted as intersecting the stator windings and thus the current is maximum when a pole is directly opposite a stator winding, not when it is in between them. One very good thing about the animation is that it explains well the light going on and off, which is a 120 times a second with 60HZ AC. It might also be useful to explain that a two pole rotor like this one would have to spin at 3600 RPM to get 60HZ, so typically they would be more rounded to keep from flying apart. It also appears the generator depicted is an induction type generator which isn't used much (yet) to power communities.
It seems the video is showing *current*, not voltage. Current is induced by a change in magentic flux, which is zero at the poles and higest between poles.

This is so much better and easier to understand than any technical manual, or Wikipedia for that matter. The generator diagram at the beginning is the most important part of understanding the principal of the phases. Well done video.
Check our new revamped 3 phase explained video, sooooo much better:👉 LINK: ruclips.net/video/c9gm_NL7KyE/видео.html
Good video, but you have made a slight mistake. The output voltage is 0 when the magnetic field through the coil is at its strongest, and the output voltage is at its peak when the magnetic field through the coil is 0. This is because the induced EMF depends on the derivative of the magnetic flux, with respect to time, and the magnetic flux is sinusoidal.
Not really a mistake, the video seems aimed at dummies like me. I understand this video enough to understand the basics. While i'm sure your right in what you say, you lost me in 1 paragraph.
It's faraday's law. The induced emf is proportional to the rate of change of flux. The rate of change of flux is highest in a generator when the flux linkage is lowest. e = BANwsin(wt)
Incorrect JT. The rate of change is the derivative. The derivative of a sine way is 0 when at max or min; it is max/min when the original signal is at 0.
So basically the lamp will light in according to a cosine wave. However, he mentioned Power, and you're talking about Voltage. We multiply Current with Voltage to get Power, so that may change things up a bit. I'm not sure, but there seems to be a discrepancy in your argument.
Great video but one more minor point, it's not the "speed" of elections that increases and decreases but their intensity, their number/ strength. Electrons always follow at a constant rate based on the speed of light.
Hey there, great video. I would just like to point out that the biggest reason we use 3 phases comes down to more than just what is reasonable for most budgets. 3 balanced phases have a very important property where the sum of their instantaneous power output stays constant when the loads are the same. This apparently makes transmission of power easier, but also means a 3 phase motor will be able to receive a constant instantaneous power from the electrical grid. With less than 3 phases that power is subject to intense oscillation and even dips below zero at times.

Wow! For 30 years I always wondered about 3 phase, and you explained it in such an easy to understand way. Cheers

You should do a presentation on how an isolation line filter or isolation transformer works. I've heard of techs using them to float the ground of test equipment while using an oscilloscope. I'm not sure I'm fully wrapping my head around this. I love your visual aid and diagrams, they really make sense.

Wonderful vid. It's odd that my mind can grasp mechanical theory easily, always had uses with electrical. This helped considerably.

I am not an electrician, nothing close, never been interested in electrical work in my entire life, but I still love watching these videos

1. Very nice animations. A picture is worth a thousand words, and an animation is even better, and I appreciate that it takes a lot of work.
2. You say that as the magnetic field moves through the coils, the electrons go faster and slower. I thought the voltage increased and decreased while the speed of the electrons stayed the same.
3. Regarding complaints about your dialect. English has many dialects and there is no "correct" one. Interesting note: most languages don't have the "th" phoneme of English. That's why they often say "zis" and "zat". Even some English dialects say "dis" and "dat". But I think many of us aren't used to the dialect that says, "one, two, free", or "froo" for "through", or "togevva" for "together". It gets easier to understand as you get used to it.
A simplified explanation is that the electrons move at the same speed no matter the voltage, they just don't move as far.
Yeah the speed analogy was confusing...
@@jovetj - You are correct that the electrons always move at the same speed. However, what changes are the number of electrons flowing around in the circuit, not how far they go. Current in a circuit is a measure of how many electrons are flowing past a certain point in the circuit each second. That's what an ampere (amp) is by definition.
@Joe Vignolo
I think we were talking about differences in voltage, not amperage.
@@jovetj - Voltage and current are directly related. As the induced voltage in the windings goes up and down the amount the current flowing in the winding and through the load also goes up and down. And the electrons always move at the same speed regardless of the amount of current. I'm not sure what you meant when you said, "they just don't move as far".
I think this video gives a pretty good intro into three-phase and some of its uses without getting into the nitty gritty that confuses people. With that said, I think adding a bit more on delta/wye load/source configurations, transmission lines, and a brief mentioning of the frequency domain could’ve helped bridge the gap between the math and the theory

Good video! Though I was missing one aspect of 3-phase electricity and that is the voltage part. In Western Europe, most 1-phase sockets deliver ~230V AC, but 3-phase appliances work at ~400V. The higher voltage comes from the time difference between phases themselves. That was a subject I found difficult to grasp when I they tought me.
The higher voltage between 230 and 400 is due to tapping the transformer coils at different places. The number of windings causes the difference.

It isn't the 'intensity' of he magnetic field that causes current to flow. It is the rate of change of the magnetic field across a coil. A strong, but unvarying, magnetic field will cause not current to flow. Actually, what the varying magnetic really produces in a coil of wire is a VOLTAGE. If the coil is connected to an open circuit, a varying magnetic field will produce a varying voltage, but there will be no current. If the circuit is connected to a load (a resistance) current will flow.
The rate of change in a revolving magnetic field is also dictated by the strength of the magnet though... A stronger magnet produces a greater difference in the electric field as it moves

Only older houses or apartments use single phase. At least in northern Europe like Germany, Austria and the Netherlands the normal houses have three phases into the house to use saws, shredders, welding equipment (these of course in rather rural areas, welding in your living room at the 30th floor doesnt't make THAT sense...), charging your car with 22kW (or even the Renault Zoe with 43kW), use direct water heaters and so on.
3x63A is normal, 3x50A is the new standard, underdeveloped regions in Germany like bavaria have only 1x35A for the whole house which is fairly enough if you heat with oil or wood and cook with gas.
3x65A seems excessive for a normal residential single family house. In Finland most are in 3x25A range. Price for 65A feed is quite a lot more than for 25A. Even for a car charging you do not need to fill it in 45 minutes, as you usually would do it overnight. And heating by direct electricity is not efficient without sometype of heatpump.
