  • High-voltage direct current - Wikipedia

    A high-voltage, direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems. Most HVDC links use voltages between 100 kV and 800 kV.
