Answer / 7anoter4

If the primary voltage [supplied by Utility] it is NOW 11
kV and your transformer at no-load shows 720 V at its
secondary terminals the ratio primary/secondary voltage is
11/0.72=15.278. If you want to reduce the secondary to 700
V you have to change the ratio to 11/0.7=15.714.

Let's say the rated secondary voltage [at no-load] is 720 V.

That means the ratio 11250/720=15.625 it is the most
suitable and you'll get 11000/15.625=704 V at secondary
terminal [at no-load].
