  2. High-voltage cable - Wikipedia

    en.wikipedia.org/wiki/High-voltage_cable

    High voltage is defined as any voltage over 1000 volts. [3] Those of 2 to 33 kV are usually called medium voltage cables, those over 50 kV high voltage cables.. Modern HV cables have a simple design consisting of a few parts: the conductor, the conductor shield, the insulation, the insulation shield, the metallic shield, and the jacket.

  3. High-voltage direct current - Wikipedia

    en.wikipedia.org/wiki/High-voltage_direct_current

    Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

  4. Submarine power cable - Wikipedia

    en.wikipedia.org/wiki/Submarine_power_cable

    A submarine power cable is a transmission cable for carrying electric power below the surface of the water. [1] These are called "submarine" because they usually carry electric power beneath salt water (arms of the ocean , seas , straits , etc.) but it is also possible to use submarine power cables beneath fresh water (large lakes and rivers ).

  5. Marx generator - Wikipedia

    en.wikipedia.org/wiki/Marx_generator

    A Marx generator is an electrical circuit first described by Erwin Otto Marx in 1924. [1] Its purpose is to generate a high-voltage pulse from a low-voltage DC supply. Marx generators are used in high-energy physics experiments, as well as to simulate the effects of lightning on power-line gear and aviation equipment.

  6. Tidal stream generator - Wikipedia

    In 2013 the Deep Green pilot plant began operation off Northern Ireland. The plant uses carbon fiber kites with a wingspan of 8m (or 12m [48]). Each kite has a rated power of 120 kilowatts at a tidal flow of 1.3 meters per second. [49] Design. Minesto's kite has a wingspan of 8–14 metres (26–46 ft).

  7. Magnetohydrodynamic generator - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_generator

    The amount of power that can be extracted is proportional to the cross-sectional area of the tube and the speed of the conductive flow. The conductive substance is also cooled and slowed by this process. MHD generators typically reduce the temperature of the conductive substance from plasma temperatures to just over 1000 °C.
