Transformer Calculations Single Phase & 3 Phase with Jim Lewis 

This guy is one hell of a teacher

This guy should tell stories, I didnt learn a darn thing because I was just enjoying listening to how nice his voice is.

Thank you Jim, you help me to get my license, in Georgia, I passed in 6 hours a 8 hours test!

“Keep it simple, keep it easy and you can work any problem they give you” 👍🏽

Thank you very much, in fact it's rare to find like this video and this level of knowledge, keep it up Mr LEWIS.

Hi, I have learned more just watching this video , than in a month from reading from a book. Brilliant Thankyou

Wow! I had lots of college classes in the electrical field this is by far the best instructor I've seen, Thanks!

Thank you so much for clarifying me the process of a 3 phase transformer, I was truly confused about which formula I needed to apply. Excellent explanation, and again thank you so much!

I do believe that this is one of the best videos i have seen...Very good job

Jim, this a great session! You've nailed this... I've learned so much! Thank you for sharing this!

Great video..you kept it simple, basic and theoretical-outstanding instruction.. Thanks

Thanks for sharing this video Jim, always appreciate those who share knowledge of electrical systems, regardless of what country or system they are intended for, even if it does not directly apply to the system I utilise. Always interesting to see how things are done in different countries and parts of the world! Also, had to say I couldn't help but notice your voice reminded me immediately of Phil Harris & Rock-A-Doodle, amongst other animated features he contributed too. Really makes watching and adsorbing the information pleasant I must say.

Very good video. Thought it started out pretty slow, but kept watching and glad I did. Makes it so simple the way you explained.

This Guy is amazing, everything made perfect sense first time round. thank you

Thats unreal how easy you made this! Thank you!!! You just made my electrical career way easier thanks to this video!

this guy is a fantastic teacher.... knowledge is power

one of the most useful things on internet period. Thank you

Wow! Now I know how these transformers work at my job. Thanks for making it simple to understand.

well explained with easiest examples. Thanks for your good effort.

wow, this is arguably the best video i've ever seen on youtube and i'm including Rihanna.

Awesome video, simple and your easy to listen. Thank you for the help

you have made it very simple Sir..!!!! Thanks a lot for such videos.

AWESOME Review material!!! THANK YOU, SIR!!!

Hi, I like your lecture. Thanks

this guy managed to explain my course in 5omins my professor struggled with 14 weeks

I enjoyed your class a lot. Thank you sir, if this title haven't given to you yet

I got a lot from your video. Good style presenting the information; made it understandable.

Amazing explanation, hard to find this type of teaching today. Thank you sir

Please make more of these video! And thanks for this one :)

clear and simple, thank you very much

Thank you for your clear explanation.

Thank you this video helped alot. Explained really well Thx

very good discussion, thanks for posting it

Thank you so much. It's help me a lot.

Thank you so much sir

thanks and clear explaination i like this......very very clear...

Very informative video.Thnx.

Very clear and concise.

is the best instructor,,,

Kind of sad that there is such a low count view, this is a very nice tutorial and very easy to understand.

very good video.. excellent work..

Thanks for the video, Jim. At 5:40 you mentioned that the secondary current would be 40A. Isn't the current actually 20A, particularly in the balanced case, because "10A + 10A" current would flow in a "clockwise" loop (just a chosen convention) through the secondary winding out to the "top" 120V phase, through the loads, then down to the "bottom" 120V phase, finally returning into the winding, with zero current flowing through the neutral?

Thank You Jim !!!!

Thank you so much!

Great Video.. Sir can you explain the design of stepped core to maximize the core area Thank in advance

This is great stuff...

Wish you were in my state, I need a good teacher to prep me for my Jman exam

you made easy to understand

thank you sir !

Can you do a presentation on buck-boost transformers both single page and 3 phase? How do you calculate the size of one?

Hello I am interested in your DVD series , do you still offer the videos?

what is the level of this knowladge, i remember delta and star resistor configuration from high school but i dont remember 3phase transformers and phases power loses . But it might be i slept on class

thank you!

Thank you very much for making transformer simple i just pass my master exam with your explanation .

You're awesome.

Do you have more videos ?

Root Beer that is an amazing analogy

thanks.. clear.... industr

thank you...

Thanks

finaly! I had enough of indian teachers lol

hi. good day. wondering where can i get the handbook? thank you..

i want to ask in star or delta connection how to calculate phase current (as i want to find the line current)

Great video, too bad there's only one video. Is there someone you recommend with similar videos??

អគុណបង

Wish u were my profe

I thought there are 4 lines for a delta connection, Does it change when you hook it up to a Why connection!!??

is it me or Mr Lewis has a similar voice as Frank Underwood (Kevin Spacey)? btw thanks for the clear explanation

awesome video...ive heard of running a 3 phase motor to GENERATE a 3 phase current....how does that work, wiring wise? single phase 220 going in, 3 phase coming out

hi

here is a nice 51 minute .
