For transmission we are step up the voltage, Not only
reducing the copper loss but there are many factor 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 lines.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 factor to step up voltage is, to reduce cost of
material.To make the rigid the system.Easy for maintenance.

Can we check ELCB constantly from R1 to R8 phase in 1 no DB?
