The main consideration for operating transmission line at high voltage is (a) to increase efficiency only. (b) to reduce power loss only. (c) to increase power transmission capability only. (d) All of the above
by

1 Answer

Answer :

to reduce power loss: this is because when power is generated, it is generated at a very low voltage but because it is going to be transported over a long distance it is needed to be increase in order to avoid losses on the way such as copper loss and Eddy loss.
