Answer Posted / anuya
Basic & most important factor is transformer capacity which
can be derived by calculating all connected loads at
downstream. It will give the KVA rating.
Primary-secondary voltage ratio & vector group.
Environmental conditions like temp, etc. Application
Indoor/outdoor.
Cooling type requirement will deside the Xmer will be Oil
cooled or dry type unit.
Impedance of the Xmer.
Load type.
