This is better and more informative than my current transformer class.

This is the 3rd video I have watched in this series and I must say it has been a delight. I have come across many people who have technical knowledge... but are unable to impart that knowledge but DG has given a master class once again. I don't know where he teaches but I'd arrive at the lecture 5 mins before to get a front row seat..

Great video I had a hard time with the wiring and current path until I saw this video.

I just came across your channel, and have subscribed already. Great explanation. Also, glad to hear that you're born in Nigeria, and had joyful experiences there! God bless you in all avenues.

Mr, thankyou for education. I'M from indonesia. I so interesting for learn about electrical engginer and I always watch your video

This is a lifesaver in my transformer class.

Fantastic explanation, made it super easy to follow. Thanks!

Best explanation of dual voltage xFMR ever...:)

Already subscribed. I love your fast edits so I don't have to spend time watching you write something (such as 480 V). So, it saves a bit of time, but it also adds some variety and interest to your videos. Well done.

Great video!! Definitely great way of explaining. Thank you

Great Explanation, thanks professor :)

Great vedio, thank you 🙏

Great Video, very informative.

Thank you very much, I'm a 4th year and finally understood this lol

Very good information bro keep it up God bless

Awesome video, thanks a lot!

Very knowledgeable

I'm learning a lot, thank you. You have a great way of explaining to us, um not so "educated"....

Very concise 👍👍👍

Nice Video.

THANK. YOU.

I always picture it in my mind as parallel is like the 2 windings going over each other. X1 to x3, x2 to x4.

My personal favorites are the old antiquated Scott Connections to get half-a**ed 2 phase 110/155 volts from 480/277 / 240/208 or 240 3 phase, vise versa. And the 12 lead 3 ph motors are fun too. I went from working in the hot Arizona weather to working on guitar amps indoors. Those have some very very strange transformers, especially the output impedance matching transformers. Some of those are wound super weird. Tapped windings? Sometimes. Some of the universal power transformers have taps for 100, 110, 120, 130, 220, 230, 240 and 250 volts. Parts of Japan use 100 volt 60Hz power. Other parts of Japan use 240 volt 60Hz or 50Hz. Fiji used to have 100 volt 60Hz mains. Everywhere else is 230-250 volts @ 50Hz except for the USA, Canada & Mexico and some parts of Japan. Being separate islands it's not they are going to try to tie system one into the other.

Thank you sir, I'm from Nigeria

It's do nice one

Can I also get 220 on the secondary from a single 110 volt supply

thank you sir

Additive polarity transformers in your example, as opposed to subtractive.

So does a residential transformer involve one Delta winding with 3-phase connected to three houses? Each house is hooked up to one of the three dual voltage wye windings?

Can I install a gfci to the 120 vac output on the transformer. what about the neutral that is needed for the gfci?

Pls how do we get 220 volt from 2 ( 12/220v ) transformers if we have 12v power supply

so my max 4000watt generator would not work to get me off the grid due to the amps being so low, rated max 8amp and I need atleast 100 amps even though I'd be using a transformer 🤔 this stuff is confusing.

No offense, but for parallel primary, shouldnt h1 connect h3, and h2 connect h4 through the coils? You swapped the connections AND the tap placement. It's electrically the same as connecting in series. That error changes the parallel secondary too, unfortunately.

Teaching about transformers and talks like we are new to learning about electricity. Very boring combination.
