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.

y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
