That's all true for AC as well though.

- MertsA 9y agoThe benefit of HVDC transmission lines is that you don't have the skin effect at all which makes a difference even at 60 Hz when the cable is as thick as your arm. If you've ever seen one of those large transmission lines where each phase has three conductors all very close to each other but kept slightly apart that's done because of the skin effect. Also there's always capacitance which will cause some loss for AC but of course capacitance won't affect a DC transmission line. HVDC also makes combining different electrical grids extremely simple as there's no phase difference or frequency difference to worry about. DC also requires lower peak voltages as AC is going to be sqrt(2) times higher than the rms voltage.
