Hands down the best prof I have ever had, truly a blessing that I was in his class for electrical trade school. Peter is the definition of a teacher, one who goes above and beyond to make sure that the people learning actually understand what is going on. I actually miss being in is class bc of the amount of stuff I had been taught, which btw I thought was impossible for me to learn. Its been two years or so and I still come back for a refresher.
thank you so very much for explaining in 13 mins what my lecturer couldn’t get across in 2 hour lecture. I really appreciate it. THANK YOU

This came in real handy. Its been years since I have study electrical theory. Great refresher, thanks
This is the most informative presentation i have watched thus far.
Thanks Pete you're the best at explaining things, love learning from you!
Love to see these basic principles on video which I learned from school a long time ago. A very good refresher for me. Thank you.
Pete, thank you for your excellent video tutorial. I surmise you are an Electrical Engineer, this after following your videos regarding 3-phase circuits. I admire craftsmen like you who are knowledgeable and passionate about your job and finally for sharing your talent with the rest of us. Keep it up.
Thanks for the nice comment. I am an Electrician.
thank you for using youtube for the betterment of mankind and not some stupid vid.. god bless
Thanks for the great comment. UA-cam is such a great platform for learning. I personally use it to learn every topic I am interested in. Have a great day Joe. Pete
you have to have an ability to teach. I used to teach electronics at T.A.F.E.college. Most of the instructors who had been there for years didn't have that ability, drove the students mad. My first day of teaching, my students gave me a wonderful compliment "thanks Baz, you are the best teacher we've ever had, this was day 1! I was sacked shortly after, because my students actually learned to love what they were taught.
You, Steve, are definitely in that category, I am 60 and retired, but I love your video's because you make it so interesting,
Baz :-)
God bless you sir!
I used to teach this stuff years ago. Sad to say and I suppose for most of us, is if you don't use it, you lose it. I knew these things in minute detail, but now it is like a foriegn language to me. I wish I could remember everything I spent so much time learning.
Just started as a P&C electrician. This is an amazing refresher
You explained a couple things I couldn't quite grasp. Appreciate it
Pete I took intermediate with you last year...I am at Algonquin now for advanced after moving to Ottawa. Your instruction is so much better.
So jealous. I wish I had moved to Ottawa after finishing school. Such a great town. My wife grew up in Manor Park. All the best. Pete
amazing, this is the best teaching of transformer i ever watched, many thanks
Thanks for your videos,I'm only a beginner and I see the classes very interesting
Glad you like them Everardo. All the best. Pete
Very clear & informative. Great job
This is excellent dude counties with the good work.Wonderful !!!
Thanks so much for the nice comment. All the best. Pete
I’m going to take electrical power PE test again and your videos have been an excellent practice. You should put on the title of the playlist that this is an electrical power PE review
Thanks for the tip Daniel
These are amazing tutorials. Thx
Very helpful video! Thank you.
Thanks Pete Great works amazing. Thank you
love your videos!
very easy to understand, thank you!
Helped me a lot. thank you it was great.
Great lesson! Thank you sir
Thanks for the clear explanation.
I have a test coming up, and this vid helps me alot.
Excellent. Here is the complete play list for 3 Phase Circuits: ua-cam.com/play/PLyL0ResmI4Q1bG7CZDJFdZdEMqxixuW7l.html
THank You
why did it take me so long to find this playlist!!!
Very well explaining 👌🏻👍🏻
Fantastic stuff, thank you
you are a god damn saviour i have my exams in 3 weeks and couldnt grasp this
Excellent. That was my hope in making the videos. So glad it helped. BTW there is a playlist that builds on this video, ua-cam.com/play/PLyL0ResmI4Q1bG7CZDJFdZdEMqxixuW7l.html and you may want to check out Jim Pytel's channel. He's a little condescending, but his videos are really good. ua-cam.com/users/bigbadtech
@@PeteVree A "little condescending"? I work HARD to keep my sarcasm on point! Great job on this material Pete.
Thanks Again, Pete:-)
great work thanks
wondering: if you did kva/VL does that equal IL ? or IPh
Good job
This is gold.
thank you very much
i love this
Hello hope all is well, is it proper to say that the coils are connected together but you don’t get a short circuit(touching phase to phase) because they are out of phase by 120 degrees, meaning each phase is going thru the coils at separate times. Thanks in advance.
Do u have a video in open delta?
i have a question. when do you multiply by 'Sin or cos ' when solving for VA ??
Cos is used for the Resistive Values (i.e. Wattage), Sin is used for the Inductive or Capacitive values (i.e VAR's)... you also use Cos every time you are finding the VA when you know the Wattage and the Power Factor (VA=Wattage/PF) because PF=Cos of the Angle
Clear concise. With a Power factor of 1 ( all resistance load)
the VA (volts amps) number would be the SAME as the Watts number?
FOR the transformer? Trying to learn, thank you.
Yes. Purely resistive loads have all their power expended in the form of heat, so Watts = VA in this case.
why the dislikes?? it's a great video!
nice tutorial
bie dankie my bro.....thank you very much
geen probleem
Could a delta connect alternatibgly with a 3 large capacitors will be a trapping power supply could inductively supply a 3 layers ca pacitors connected to load became forever power supply? 70% posible
THANK YOU
why do you multiply by the root of 3 to find the Line Current
Cheers mate..
Sir plz tell me star Delta connection star contacter how many amper in 10 hp motor formula
Thank you
How do I get my power factor?
Cool video
can 2 welders ac.power has 20 kw3 ph each ,can they hooked together to supply 40 kw 3ph.
No idea Jim... maybe this will help: www.google.ca/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwjbjM3ln5fXAhVS02MKHTQzAaQQFggoMAA&url=https%3A%2F%2Fwww.millerwelds.com%2F-%2Fmedia%2Fed7eea451a2d4c9e981e53ba045d65bd.pdf&usg=AOvVaw3xleuX6U47JTkT9xonJssX
what is actually going on with the transformers?
WHY THIS VIDEO IS HIDDEN AT THE BOTTOM IT SHOULD BE IN THE TOP TO EASILY FIND IT!!! NICE WORK
Thanks. What playlist did you view it on? It is on the top of these 2 playlists:
ua-cam.com/play/PLyL0ResmI4Q2DlF6EzEuA2BxgFhnh3PgQ.html
ua-cam.com/play/PLyL0ResmI4Q1bG7CZDJFdZdEMqxixuW7l.html
230/415 V is the British system used in Asia and Britain
Do we ever need to consider the phase angles for power? Thanks
The resistive power component would be "in phase" so we are assuming an angle of 0 degrees
Amazing video-Quick question: what would cause my voltage to ground on one leg to be 280, but climb to 430, and then back down, and so on (in the course of 30 seconds). This only happened on one leg, not the other two.
No idea... but if you ever figure it out, come back and add to your comment.
You most likely have a Wye Wye with a bad neutral on the problem phase.
@@intheharness A why with 277 volts on the phase to star point ( neutral). And 480 volts line to line? trying to learn. thank you.
could you do more videos on controls? I would be willing to pay for the dvd's
No problem. Any particular topic in controls... I'll have more later this week on basic circuits like push button fwd rev, etc. The beauty of UA-cam is we enjoy providing the videos for free.... knowledge is to be shared, and this is a fun hobby for me.
You tha man
yes thanks you
Thanks Pete.
Thanks
Even if my english is not good, it seems to be a perfect video. Thank you. But what about a generator? Alternator in delta?
Doesn't matter if it is a Generator or a Transformer, same rules apply
thanks
Why is the line current 17.32 A on line 1 instead of line 3 10:06
The line current would be 17.32A on all lines. It's a balanced load. I just wrote the current on line 1 to keep the diagram clean, but L2 is 17.32 and L3 is 17.32
Can yolu tell me please if I know this information what kind of job I can get
Understanding 3 Phase is a fundamental for Commercial and Industrial Electricians.
First of all, I really appreciate your lecture, which really helps me a lot.
But English is not my mother tongue,
hence it is a little bit hard to absorb.
If u can turn on the cc subtitle, that will be helpful.
THK.
Strange. For some reason it won't allow me to enable the CC subtitles for this video. I will have to investigate a third party software to scrub the video and extract the subtitles.
Can u pls make a video for dummies
so the watt was 31176 Watts ???
This video doesn't mention what the Power Factor PF is, so we can't find the Wattage at this point. The videos later in the playlist will look at converting the VA to a W value.
How is I(L) = I(phase) * √3

That’s a big tfmr
The dogs bollocks in electrical theory
I'll add this to my resume.
