Can we use generator transformer as step down transformer?
How?

Answer Posted / atif rasheed khan

there are two cases arises here, in first case our answer
will be yes under the following condition.
the generator should be so excited till its voltages
produced be equal to the previous step up voltages done
through transformer, however these rise in voltages are just
restricted to 33KV, because beyond this voltage level there
arises a critical issue of the winding insulation.
in this method just reverse the connections, i-e change the
L.T as sending voltage side, and the H.T as generation side.
however in the second case , our answer will be no, if
higher voltage step up transformer are used, due to the
above mentioned problem of insulation of transformer.
