Answer Posted / raj
the applicable voltage is 11,33,66,110,220,400 kv like wise for various applications if we covert direct 33 - 440 we didnt get and have to make more expanses 33,11 kv medium voltage uses.
.in power plant electrical design is like wise 440 to 220- 220-11kv or 33 kv ,11-440v aux supply purpose.
in transmission wise step up/step down for mainly losses.
