Is it feasible ? Thanks in advance for help.

then transformer with less reactance will carry more load compared to rating of that transformer & cause overload on that transformer

HV side:-33 kv
LV side:-11kv
1.what are the loads on both the transformers?
2.if maximum loads taken of the both transformers…what will happen give examples

Because in practical it couldn’t be 100% same.
