How Three Phase Electricity works - The basics explained

In this video we learn how three phase electricity works from the basics. The basics of Three phase electricity explained. We start with a simple single phase AC generator and then add in a second and third phase to under stand its working principle. We also cover three phase power uses and distribution as well as why we don't use more phases.

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.

[MayurPanghaal]

Most of the confusion in a student's mind is caused by bad teachers who do not know the basics themselves.Thank you for doing a great job.

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

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. 👍👍

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!

[BTCIVDevKrishanDixit]

What I learned in 5 hours of Class+ Studies, He explained in 8 min, I appreciate this. Keep making these Great Videos. Thanks.

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!

[benryals]

I typed in “3 phase electricity explained” the first five videos were a math class. This is exactly what I’m looking for. Thank you

[chaosfox]

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.

[clarenskybenoit]

A whole freaking semester in AC circuit Analysis and I couldn't understand that three phase power concept because my 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

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.

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!

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.

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!!

[SteedSchool]

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!

[Phil_AKA_ThundyUK]

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.

[bigyeticane]

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.

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.

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!!!
