Question: How is it (on an Open Delta setup) that only two legs (120 degrees apart) are being supplied to the primary, and yet a third leg appears in the secondary 120 degrees out of phase with the other two? If “Three phase is nothing more than three single phases being generated from the same generator 120 degrees apart” (and I get that). Then it seems like you would have to use all 3 phases in the primary in order to get all 3 in the secondary to be 120 degrees out of phase. How come the 3rd phase on the secondary doesn’t match phases with one or the other of the only 2 supplied? Some type of mutual inductance vector shifting going on???
probably some people conect their phases just not trusting and checking rotation because any of phases can be L1, it's necessary only to know wich is next after first connected, maybe more phases need equipment in order to not burn one or more coils. In Europe we use unitar delta-star transformers usually which make new installation simple even with less qualified personnel sent in villages, bare wires without color or order, at consumer installing a tri phase motor it's necessary to find out which one it's next from all 3 identical coloured phase wires,
Newbie here, I can’t wrap my head around how using only 2 phases in makes 3 phases out that are all 120° apart. Is there an easy way to explain here in comments, or a video on here? Or is being 1-1/2 hops away from the neutral making a high so.. sorry I can’t even explain that thought.
I have a video about generator fuel pump that advice to run this motor first just to check the roation before energising all the induction motors on the plant.

Got me with the cow story!
This is a great intro explanation to transformers.
Thank you so much for this video!
Great explanations! And the box fan in the window, haha, We had the same growing up.
Thank you for the video and sharing your knowledge.
Thanks for this!!

Very nice information bro thanks

Anything to show how you get amps for high side wye
Open Delta ( 2 transformer example)?
Cross two wires, meaning REVERSE two wires?
If the farm story were true it would have been a tragedy 😂😂💔
