Which of the following statements is INCORRECT regarding high-voltage overhead transmission lines?

Verified Solution4 OptionsUpdated: October 2026👁️1 View

1With an increase in transmission voltage, the required insulation between the conductor and the grounded tower increases.
2The cross-sectional area of the conductor decreases with an increase in transmission voltage for the same power transmitted.
3Line losses are reduced due to a reduction in the current-carrying requirement, resulting in better efficiency.
4The voltage drop is reduced due to low voltage, which does not improve voltage control.✓

Correct answer

The voltage drop is reduced due to low voltage, which does not improve voltage control.
