Assertion: The use of HVDC (High-Voltage Direct Current) transmission ...
HVDC transmission systems are preferred for long-distance power transmission due to several advantages, and one of them is lower transmission losses compared to HVAC transmission systems.
HVDC systems operate by converting AC power to DC power for transmission and then converting it back to AC at the receiving end. This enables the transmission of electrical power over long distances with lower losses. HVDC transmission systems experience lower resistive losses and reduce the impact of reactive power, resulting in more efficient power transmission.
The lower losses in HVDC transmission systems make them suitable for transmitting power over long distances, especially for interconnecting power systems across continents or regions.
Therefore, both the Assertion and Reason are true, and the Reason provides a correct explanation of the Assertion.

Assertion: The use of HVDC (High-Voltage Direct Current) transmission ...
Assertion:
HVDC transmission systems are advantageous for long-distance power transmission.

Reason:
HVDC transmission systems experience lower transmission losses compared to HVAC transmission systems.
  • Explanation:


  • Advantages of HVDC for long-distance power transmission:


  • - HVDC systems have lower transmission losses due to the absence of skin and proximity effects, making them more efficient for long-distance transmission.
  • - HVDC systems can transmit power over longer distances without significant voltage drops, making them ideal for interconnecting grids over large geographic areas.


  • Explanation of the Reason:


  • - The Reason provided is correct as lower transmission losses in HVDC systems contribute to their efficiency in transmitting power over long distances.
  • - The ability of HVDC systems to maintain stable voltage levels over long distances also supports the assertion that they are advantageous for long-distance power transmission.


Therefore, the correct answer is option 'A' - Both the Assertion and Reason are true, and the Reason is the correct explanation of the Assertion.
