Answer / hamdi,ahmed

Step down transformer is high voltage low current in primary and low voltage high current in secondary so the remaining 22kv converted to a current according to transformer parameters.

Answer / prof. dr. k. manjunath

Transformer transfers the power from one circuit (primary)
to another circuit (secondary) at constant frequency. If
voltage at circuit is higher then current will be lower in
magnitude whereas another side, the voltage will be lower
and current will be more.

Answer / narendradalai

The power & frequency both are constant in transformer.
V1/v2 equal to i2/i1.
V1i1  equal to v2i2
P1  equal to p2
So remaining convert into current. 

6 MVA transformer secondary is rated for 725V at no load. The incommer ACB is rated at 690 V, 3200 Amp. Would there be any effect on performance of ACB due to lower voltage rating?
