Explanation of Series and Parallel connections for Transformers with Dual Voltage Windings in order to achieve higher or lower voltage options on either primary or secondary.
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..
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.
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.
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.
The open delta is kinda like the Scott connection. Same purpose, and beware of these weird ones! There was also the TT (same as The Scott). The audio transformer engineers get really creative for impedance matching. Some of them are less than optimal and not very efficient, plus a change in output taps results in notable changes in the sound. The inductance, reactance & capacitance in the coil windings changes very drastically in some of the goofier designs.
Thank you for mentioning your country. I am also a child of Nigeria as I spent the first 15 years of my life on the Jos plateau. Climbing mango trees, picking guava, eating koose (akara) and suya (tsire), riding my bicycle, and generally enjoying the beautiful people and environment of Nigeria. I had a blessed childhood. May God bless Nigeria, and bring peace and prosperity to the land of my birth. I should add that even though I use U.S. voltages in most of my videos, the principles are the same regardless of nominal voltage differences around the world. Thank you.
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?
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.
This is better and more informative than my current transformer class.
Yes you are right

Great video I had a hard time with the wiring and current path until I saw this video.
This is a lifesaver in my transformer class.
Great video!! Definitely great way of explaining. Thank you
Best explanation of dual voltage xFMR ever...:)

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

Mr, thankyou for education. I'M from indonesia. I so interesting for learn about electrical engginer and I always watch your video
Great Explanation, thanks professor :)
Great Video, very informative.
Awesome video, thanks a lot!
Great vedio, thank you 🙏
Very concise 👍👍👍
Nice Video.
Thank you very much, I'm a 4th year and finally understood this lol
Very knowledgeable
I'm learning a lot, thank you. You have a great way of explaining to us, um not so "educated"....
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.

It's do nice one
thank you sir
Thank you sir, I'm from Nigeria

@@davegordon6819 wow, that's amazing, I'm happy you left

Additive polarity transformers in your example, as opposed to subtractive.
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.
Can I also get 220 on the secondary from a single 110 volt supply
upstep trasformer yeah

Maybe for 240v but he’s talking about 480v incoming.
Teaching about transformers and talks like we are new to learning about electricity. Very boring combination.
Very good information bro keep it up God bless
