WebHVAC stands for High Voltage Alternating Current while HVDC stands for High Voltage Direct Current. These are generally the range of voltage either AC (HVAC) or DC (HVDC) that are used for power transmission over long distances. However, HVDC is preferred to be used for transmitting power over long distances usually more than 600 Km. WebThe HVAC transmission requires a minimum of 3 conductors for 3-phase power transmission while in case of HVDC that can utilize the earth as the return path can use only 1 conductor for mono-polar transmission or 2 conductors for a bipolar transmission.
