why we step up voltage for reducing the loss, even if
voltage and current are proportional anr resistance remains
same
Answer Posted / pranav pathak
For transmission we are step up the voltage, Not only
reducing the losses but there are many reason to step
up the voltage
1) Transmission line conductor is calculated behalf of
current capacity.To transmit high current we have to
provide big diameter cable/line, and big diameter line
cable weight is more.Which is costly, Tower cost
increase.
2) current less means conductor diameter size will
less.Conductor cost will be less.
3) Obiviously the copper loss is dependent upon current,
Current less, It will help to reduce the copper loss.
So main reason to step up voltage is, to reduce cost of
material.To make the rigid the system.Easy for maintenance.
Exm.:- In generation station first we generate 11 kv, and
after generation we provide stape up transformer.
