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

[@davidk813]

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

[@BigDBran]

Was just about to say that. Correct sir.

[@jackfayne7944]

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?

[@ZackHartle]

Definitely! Oops

[@ratedmark4704]

Caught that real quick.

[@larrygerlin1733]

Great video. Explanation was very clear

[@zhumusic-ng9tr]

Best video i found for quick differences

[@eppersonelectrical1621]

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!

[@davidchavez81]

Think about it. What is he writing on? Something transparent. What does writing look like from the other side? Backwards. What does mirroring the video do? Puts things that are backwards right side forward. This technique is not unique to this guy and notice he is apparently using his left hand to write? Almost all people who make videos like this appear to be left handed, even though they are not.

[@tedlahm5740]

@@davidchavez81 Clear explanation.

[@matthendrickson5538]

😂 same here....i think i liked it better before i read the helpful explanation.

[@mattp1000]

I should have never read this comment because it just distracted the hell out of me.

[@ZackHartle]

It's just fancy camera trick. I'm a regular right-handed person with no skill writing backwards/

[@natejenkins8725]

Thank you Pablo. You are a man of the people

[@praveenvarma1369]

Good explanation! If I have two transformers (1&2) connected to each other; should the secondary connection of the main transformer (1) be the same configuration of the primary of the second transformer (2) ? Eg. should the connection be delta-delta ?

[@Chinhnguyen0497]

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?

[@joelchavez7395]

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

[@85agyoung]

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

[@ZackHartle]

Yes

[@shauns6936]

Love it man! Keep it up

[@wolfenstinehoffman5753]

Is the recording mirrored or is he writing everything backwards?

[@Ezzell_]

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

[@sambathbunkh]

Very very useful video and explanation

[@ramamohangadiyaram9004]

Thank you very much for the great explanation.

[@zhumusic-ng9tr]

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

[@Manameisjeffzz]

Elevators

[@AllAroundHnadyMan]

Excellent Educational Video!

[@monampuan2083]

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

[@TheCatFather01]

Secondary will be wye

[@gamelover2594]

nice explanation Mr. Zack!

[@ZackHartle]

Glad you liked it!

[@FullOilBarrel]

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

[@jeffreyyoung4104]

Inductors. Resistors are zigzag lines.

[@ZackHartle]

This is inductors indicating the source. Windings of an alternator or secondary of transformer

[@FullOilBarrel]

@@ZackHartle Thank you!

[@jeanclaude2794]

thank you sir! ur a champ!

[@jeanv4871]

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!

[@ZackHartle]

Sorry, no. But if there's topics you think would make good videos, let me know

[@hoalehai8154]

Please explain why we have square root of 3

[@TheCatFather01]

You have 3 phases

[@anthonywooten9930]

It’s the phase times 1.732 that gives us the line voltage in a wye system, 120 x 1.732 = 208. Sqrt 3 is a necessary constant for 3 phase power.

[@raminmollahajloo4059]

Good job 👍

[@MH-fp6nv]

Are you writing backwards the whole time?

[@ZackHartle]

Just fancy camera tricks!

[@Por-poI]

Hes writing with the screen in between him and the camera and since that would be reversed, he would then mirror the video in editing.

[@Mike79555]

😂

[@erikyoung256]

Cool dea!; Thanks 👍 for that explanation

[@mrlectronics7916]

Por fin lo entiendo, gracias¡

[@RoyHoy]

I'm just wondering how you write backwards lol

[@brandondasher5335]

he has a piece of glass in between him and the camera. He just writes normally on the glass with dry erase markers which he has backlit with a light just off screen (appears viewers right on the video) so they look really bright. Then he films the video. From the cameras perspective all the writing is backwards. He mirrors (inverts) the video in post and all the writing is normal to the viewer.

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.
