Question

Give the comparison between HVAC and HVDC transmission.

Answer 1

Thus, clearly, HVDC transmission line would cost lesser than an HVAC line. However, the terminal converter stations in HVDC are much more expensive which are not required for HVAC transmission. ... An HVDC line has considerably lower losses compared to HVAC over longer distances.



HVAC is short for Heating, Ventilation and Air Conditioning systems, mostly as implemented in large C&I (Commercial and Industrial) buildings. HVDC is short for High Voltage Direct Current - often used in long distance electrical transmission system.

Answer 2

• HVAC transmission requires a minimum of three conductors.

• The HVDC requires only two conductors in bipolar & one conductor in monopolar transmission.

• The HVAC transmission is used for less than 600 Km distance.

• The HVDC transmission is used for transmitting bulk power more than 600Km distance.
