Thanks Mr VinotKumarkkp for your comment but I think there are other reasons like to reduce the shortcircuit inpedance toprotection accurancy and other effect that I am trying to find out
Bye

This is totally dependent on voltage drops. But u dont consider voltage drops then one main reason is also that hv conductor size is less than lv conductor size. I think this is reason.

no EB power DG is not starting?
The capacity of the transformer is 20/25 MVA, Ratio is 132/11 KV, Vactor group YNyno. and impedance is 10.07%. As per the calculation the secondary current is 1312.2Amps. The maximum fault current the transformer should sustain is 13.030KA. How many times the transformer should sustain the maximum short circuit current of 13.030KA over a period up 1 Year. The transformer is repaired one & 10 Years old.
