I just wonder how a single phase tapped Transformer is a delta

Awsome video! Please confirm if the 8660V voltage requirement is a line-ground or line to line voltage.

Yes this is very informative and understandable.

Transformer hookups. Optimus Prime is going to get lucky.

Awesome video

Hey man, I hope this comment gets noticed. Can you recommend a book where to learn these kind of stuff? I'm really interested in the way you represented connections and phase angles.

This is by far the best explanation I’ve ever heard

soo many ways to set up transformers , most are pre set , 120 , 120/208 , 460 ect .

What is your primary voltage?

Would you worry about the impedance since the primary side is tied to system neutral since the x1 and x3 are tied

Why he say inches ? Is voltage confuse for me because inches are for long

Do you leave the tank ground for all three X2 as well

Between the one bushing TX and the 2 bushing TX is one better than the other

good explanation, thanks!

I have been the industry 40+ years. This is the most comprehensive explanation ever.

On the wye/wye bank you only have two bushings. If there were three bushings on the secondary side would you use x3 and x1, or x3 and x2? I can’t remember what happens with x2 on the wye wye bank.

first, is optimus prime even free?

how did you get 7200 volts to the can ?

What is the make / model / manufacturer info for this transformer?

Will you not change polarity if you swap the high sides?

In a previous video you said that a secondary connection of this type was "delta." I don't see how that is true since you are using a neutral.

This is a great explanation. Coming from a utility that has a majority of wye-wye 3 phase transformers, im trying to apply to a utility that does 2 or 3 pot/can clusters, and mostly 120/240 with the occaisional 208 power leg. This makes it so much easier to understand.

L1 and L2 are phases on the secondary side

Thats because electricians dont work with high voltage

when you install the transformer at the customer's place, does the center tap gets connected to the Grid's neutral (the one that runs along 7200V lines). In other words, is there another wire that connects the center tap and the grid's neutral?

I really like this lesson it is very well done. One thing that maybe should be explained is on a wye secondary we parallel the secondary alley cat bad dog. I know you did that because you only show x1 and x2 my apprentice ask why you only show two bushings and I explained. I still watch your videos from time to time to keep me sharp. Please keep these videos coming you are a great teacher. Thank you so much.

Can you tell us the name of the manufacturer of the transformer in this video?

On a 277/480 overhead TX would the amp rating be the same as you parallel a 120/240 TX.

As a licensed PE this guy knows his stuff but how is he working at ground level without full protection? Is this a training installation?

Thank you for all of your videos they’re super super helpful!!!!!! Please make more for all of us !

Thank you so much for the explanation!!!!!

This is the best damn transformer explanation video i've ever watched period.

Great vid once again. Very simple explanation of difficult concepts. You really know your electrical theory, but also, how to explain it in better terms (I think saying “simple terms” makes it seem like we’re idiots and we aren’t!).

One of the best descriptions of phase angles and connecting xfmrs Ive ever seen

Enjoying your videos. Dumb question: why is this called a “single phase” hook up when there are actually two 120V outputs that are 180° apart ( i.e. 2 phases)?

good teacher, you are the best ❤❤

I love watching and learning from your videos. Im not in the field but but i was always extremely interested in your type of work since a very young age. The way you explain how these setups work is extremely easily understood. Hope to see more videos in the future. Thanks !

Great video an explanation. Even a beginner can follow this demonstration! When will you be making more videos? Just came across your channel.

Nice ! It's similar to how I determine windings on a 3Φ motor. I'd never given thought to how a transformer applies.

Pedantic electricians don't like when you refer to L1 and L2 as "phases"

Thanks for this video. Easy to follow refresher course for me. I never worked on utility side of anything, but I understand it. I' m retired Inside Wireman and Millwright of 36 years. Btw, On a former agri property, I'm extra lucky to have 240 hi leg delta serving my house and shop building.

Question, on the board in the shop you had A feeding the power pot and B feeding the lighting pot? Wouldn’t that give you counterclockwise rotation?

explained 🙂

nice and easy😀

Thank you for teaching me high voltage and understanding it better.

I have learned so much from this video , Thank You so much for this amazing knowledge Sir

nice and perfect

What about the voltage of 120/ 208 for a customer? Typically in my area when a customer requests 120 / 240 volt 3 phase service it implies it's a Delta high leg service. Meaning one of the phases is 190 volts to neutral or ground

Your videos are wonderful. Take a bow for a job well done!

Watched everything on your channel. Hoping for more videos soon!
