Which of the following is NOT true in the case of High voltage transmission?
Answer: A
The statement that the size of the conductors will increase is not true for high voltage transmission. For a given power, \(I = P/V\), so a higher voltage means a smaller current, and the conductor cross section needed to carry it (and so its weight and cost) decreases. The other three statements are true: the \(I^2R\) losses fall, efficiency rises as a result, and the voltage drop (and so the regulation) is better for the same power delivered.
