Transformer Polarity

This video explores additive and subtractive polarity in a transformer. This is determined by the windings and markings of H1, H2, X1, and X2.

Every electrician including me learns this in school and a textbook. This video helped me wrap my mind around the subject a bit easier. Thank you

[@joey_outdoors]

Better than my textbook. Thanks!

[@sodiumvapor13]

This was never explained to me and you did a great job with this presentation!

[@melplishka5978]

I’m sorry I’m missing something. How can you have specific polarity in an a/c environment??

[@melplishka5978]

Hahahaha I guess I should’ve waited till the end of it lol. I see it’s the current you’re talkin about lol. Sry bud I get it now lol.

[@beauwoodbury1112]

Omg thank you so much I was trying to learn this from a textbook my brain couldn’t hack it

[@ethanparkerson4333]

How do I know which is the hot leg on the secondary. Is H1 always negative?

[@insylem]

Is there any differences in the transformers themselfs? If you connect H2 to X2 in the additave transformer, would it work exactly the same as the subtractive one? If you connect H2 and X1 in the subtractive transformer, would it work exactly the same as the additave one? How are these different than buck/ boost transformers?

Did you ever find an answer to your question?

[@lexvanheel]

good explanation of transformer polarity. Thanks

[@ryanhryniuk923]

Great video sir ! Thank you

[@eclecticlearner5943]

Solid video as always Zack 👌!!

[@MBSUKTU]

Good day sir. How can I turn my 4 face transformer into 3 face secondary 12v dc

[@anishpatel3480]

Superb explain. Now No any doubt. Thank you sir 🙏

[@tedlahm5740]

Wonderful information. Believe the DIRECTION of the secondary winding compared to the direction of the primary DECIDES if this in an additive or subtractive transformer?

[@ZackHartle]

Correct! It's all about how it is wound

[@Canuck2k10]

Hey Zack! Great videos! Super helpful while I'm in school. Any chance you could make an IP prep video? Thanks!

[@ZackHartle]

I mean, aren't they all kind of IP prep videos?

[@Javier-u8p]

Always intriguing 🤔

[@jayson7991]

what are you using to draw the lesson? (whiteboard but clear and it's the right direction when i view the writing)

[@ZackHartle]

Just a clear whiteboard and some fancy camera tricks. I'm writing normally for me and inversing the image.

[@sisir22]

very good idea abt polarity

[@toddjensen2352]

Thank you thank you very informative. So do I have to purchase a additive or subtractive Transformer or can they be wired differently to achieve the result

[@ZackHartle]

It depends how they are wound when manufactured

[@sultanalhammadi2910]

Brilliant explanation. Just a small question, why is this concept important when paralleling transformers?

[@ZackHartle]

Just so that when you connect them, all the polarities work together and not against each other

[@mogwarrior49]

What was over there at 1:20?

[@ZackHartle]

Just some notes probably. Sometimes I lose my train of thought. Ha ha. Thanks for watching!

[@dentonbitter624]

Hey great video…. Would to know do you do one and one lesson need help with three phase transformers I will pay you for your time test coming up ..

[@ZackHartle]

Sorry, I don't do lessons on-on-one If you have any topics that you think would make good videos let me know. I have a lot of 3-phase transformers in the works, but they won't be out for a bit. Good luck!

thank you sir you got a subscriber

[@ZackHartle]

Thanks for the sub!

[@smferreiro2610]

Are these transformers or auto-transformers?

[@ZackHartle]

Just regular single phase transformers

[@suhailasaba1051]

@@ZackHartle Can they be named as auto-transformers ?

[@amirbahrami2309]

Thanks!!!!

[@johnaweiss]

Does "H" mean Primary? Why not use "P"?

[@ZackHartle]

H is for High, so the higher voltage. For a step down, it would be the primary.

[@johnaweiss]

@@ZackHartle So "X" means Low. Are H and X universal conventions for High and Low?
