What's the Difference Between Wye and Delta? Current and Voltage Relationships Explained

This video compares Wye and Delta 3-Phase Circuits. These basic fundamental rules apply whether you're looking at sources or loads.

Understanding these basic Voltage and Current relationships is crucial to understanding 3-Phase Electrical Theory.

Slight mistake at 2:32 you say voltage is 240 on the line. But you explanation is 120*sqrt(3)=208.

Dude, excellent video! I was following you really well halfway but then I got super distracted because I realized you were writing, backwards and then my mind went to some really weird places and then I got super confused on how you were writing backwards and was this video being mirrored I got completely lost!

Thank you Pablo. You are a man of the people

Best video i found for quick differences

[larrygerlin]

Great video. Explanation was very clear

[jackfayne]

When you were explaining the wye system you said the phase voltage would be 120 and your like voltage would be 240 but wouldn’t that actually be 208 not 240?

Thank you very much for the great explanation.

Mr.zack you are the fucking man !! Explaining what our journeymen never taught us ! .. doing God's work brother 🙏

Look I know this sounds immature, but after a few videos, you people could have just said, the starting phase is -30/30 degrees or a 60-degree difference.

It is worse than looking up marketing statistics where you just cut the unnecessary paragraphs. But here you got the named laws that you have to pause the video and decipher and learn its not even relevant, unimportant facts which I presume is how to explain it on a test at school because if you are looking for the difference of two transformer configurations, I think you should know how current flow. That's like the first chapter of any electricity book. And there isn't of much of an explanation why unless I missed it because I tried skipping through the caff or looked up the wrong doctrine.

Very very useful video and explanation

120v wye connected system would be 208v line to line & 120v line to neutral/ground if the system was grounded.

Please help me understand better. with bldc motor
I read it on internet
Wye 1.7X less KV as Delta.
Delta 1.7X higher top-speed than wye, more current than WYE at all RPMs.
I assum delta config draws 3A, and Wye also draws 3A, then will Wye give higher Rpm than Delta?
Or both configurations have the same rpm, which one will draw more amps?

V leads by 30 lags by 30 deg. are they the same ?

[erikyoung]

Cool dea!; Thanks 👍 for that explanation

[MH-fpnv]

Are you writing backwards the whole time?

[monampuan]

How do I know in a certain 3phase load to be use as secondary supply is delta or wye connection ?

[FullOilBarrel]

Is this for inductors or resistors? Sorry not familiar with US standards for drawing

[hoalehai]

Please explain why we have square root of 3

[jeanv]

Hi, zack was wondering if you offer any one on one video classes.. my husband is interested if you could plz let me know asap! Thank you!

[zhumusic-ngtr]

In what application would you want to use delta connection over a wye connection, and vise versa 🤔??
