Thank you sir

The way you explain the theory and break down the circuit for each component is very helpful, thank you

EXCELLENT TEACHING WAY SIR

I will be very greatfull if i get answer to this question: can be ground fault if nutral of transformer isolated

Thank you Dave I really appreciated you describe this in phase and out of phase it was excellent

DC difference from AC

This man is really good he knows how to explain.He is a master keep it up

Great video and idea to learn electric voltage.

How can we know each faults in measurment method?

Great job Dave!

Excellent explanation.........

Just made me think about clockwise vs counterclockwise windings....which I assume is the controlling factor in the arrows?

Under what circumstances would we choose primary-only protection versus primary and secondary protection, or is it simply a matter of preference?

Yes, you do explain well, but your demeanor is that you are talking down to preschool children. I keep waiting for you to say "today boys and girls" or for you to look into the camera and say "I see Billy and Susan, and Tommy, etc...

" I gotta unplug it quickly cause my circuit isn't really rated for that" 😂

Well done!

Nice video!

Well done!!!

Thank you, finally made sense, thank you Jesus

Very good. Thanks 🙏

Derate, not restrict Terminology matters

What a clear, concise explanation. Thanks

5:15 the math doesnt work. You have a sin and sin(x+pi) and if you add the two waves you get 0. Hope you can help me understand, thanks!

Maybe it's easier to write VA = 3 * Vw * Iw, where 3 is because we have 3-phase identical circuits. This will also end up to VA = sqrt(3) * V_line * I_line.

Excellent teacher. A rare breed of men you belong.

👍👍

Thanks for explaining a different method to calculate the HIGH LEG to ground. I did not know using Pythagorean theorem gives you 208AVC. I've always use Vector addition.

Could you do a video on conductor sizing to transformer derating for continous duty , or terminal derating etc

Just stumbled across your channel again.. You're a great teacher. Clear. Now that I have my license this is going to be a real resource

Binge watching. So good.

Well explained. Thanks so much.

Hello, thank you for good explanation,

30, 60, 90 degrees and you get 208. Wow, I never realized that trigonometry and electricity were connected!

excellent job sir ! well explained and much appreciated !

Nearly 7 minutes was enough for me to absorb all what he said ❤❤❤❤

I guess the Federal Pacfic engineers skipped this class 😂

Please write video Hindi explanation

You good sir are a legend 🎉

Thank you good sir for your hard work 🎉

Liked -> Downloaded -> Saved Great video, amazing actually. Instructors need not waste time, just play this video in your classes and be prepared to answer any questions

EV charger company says I can't use 480V,delta has to be Y, but they require no neutral. i have 208,3 phase y service so i used transformer in reverse,could only find 75kva,delta to y transformer. I don't understand why the 480V without neutral is any different, Joe

I have asked many so called experts how a negative current could exist below the neutral and not shock you when touched. This has finally explained what they could not explain. Thank You Sir

Thank you Dave. You make it very easy to understand.

Awesome explanation. Thanks Dave!

I've been studying and not grasping the concept literally for years (failed the test several times). At 4:25 I said out loud holy shit and it all clicked for the first time ever. I can't thank you enough.

You are the don!

Thanks. It is really a great explanation.

Well done, sir ☺️

Splendid explanation. Clear as day.
