*In transmission line 11kv is genrally step up,
because due to step up voltage (for example 220 kv,400 kv)
line current automatically goes down. Transmission line
travel is in KILO METER. To avoid the HEAT LOSS(I2R).
* If current is high, current carrying conductor
also change its size. so, cost also chaned in x'mission
system. So, we always used in high voltage low current
transmission system

Answer / venky_eee07

In transmission line we can step up the voltage 11KV to 132
Kv,230Kv,400KV and to reduce the losses .

Answer / jitender kotwal

AT GENERATION STATION ALWAYS 11KV LINE FURTHER WE CAN STEP
UP TO REDUCE THE LOSSES IN TRANSMISSION AND ALSO TO REDUCE
THE SIZE OF THE CONDUCTOR

Answer / kather basha

First of all we have to know that 11KV which is generated
from Generating station end will be stepup ed to 230KV 0r
more inorder to avoid losses, this case in only in
Transmission line.

But when going to distribution end S/S 11KV & 33KV S/S are
made stepdown inorder to use it as commercial load for
industries & household etc as 230V, 420V.

Answer / aashritha

To reduce the heat loss by the heating element in the wire, the voltage is stepped up
