HVDC is commonly used to transmit electricity over long distances by overhead transmission lines.

• A. True
• B. False
• C. It is used only underground
• D. It is used only for local distribution

Answer: (A)

High-voltage direct current is a practical choice for moving power over long distances because it minimizes losses and avoids the reactive power issues that complicate alternating current transmission. By converting AC to DC at the sending end and back to AC at the receiving end, power can travel efficiently over many kilometers, and it’s especially easy to link grids that aren’t synchronized. Overhead transmission lines are a common and cost-effective way to implement HVDC for long-haul routes, offering easier deployment, maintenance, and cooling compared with buried cables. While HVDC can also be laid underground or undersea when necessary, overhead HVDC lines are widely used for long-distance land transmission. So the statement is true.
