Default Step up transformer 240V to 480V 3 phase

Gunner Asch fired this volley in
:


Odd..I do it regularly.


What, at no load? Gunner, I worked for a couple of years in the
design and testing lab of Florida Transitron. I know just a bit about
them, and have made many from scrapped parts of others, since.

A 2:1 step-down transformer is NOT wound precisely to 2:1 ratio,
unless it's: 1)so lightly loaded as to constitute virtually no load at
all, or 2) working at much higher frequencies than 60Hz (and even then
loading plays a factor).

I know you don't understand that the secondary has resistance, or that
the core has hysteresis losses; but they do.

(Gunner... again!)
