No immediate harm ,but during maintenance this 11kv line
between VCB and transformer need to be discharged with out fail,
Also during switching action their would be switching surge
created due to oscillating of wave between vcb and
transformer which will heat and may damage insulation of
transformer.

Their would also be control voltage drop for 1000mtr wire
which will have significant effect on protection of transformer.
but proper control strategies will sort this problem

What is the pro & con of having 11kv & 33kv incoming, and what is the adv & disadv. of converting from 11kv to 33kv.
