SUMMARY
HVDC transmission line voltages are denoted as +/-500kV, indicating that one conductor operates at +500kV and the other at -500kV relative to ground, resulting in a total voltage difference of 1000kV between the two conductors. This configuration allows for efficient power transmission, as exemplified by the Clean Line Energy Partners, which operates at ±500kV and transmits up to 3,100 MW. The Pacific Intertie operates similarly at ±600kV, delivering up to 3,500 MW. Understanding this voltage notation is crucial for comprehending HVDC systems and their capabilities.
