  2. Interconnector - Wikipedia

    en.wikipedia.org/wiki/Interconnector

    An electrical interconnector allows electricity to flow between separate AC networks, or to link synchronous grids. [2] [3] They can be formed of submarine power cables or underground power cables or overhead power lines. The longest interconnection as of July 2022 was the 2,210 km Hami - Zhengzhou delivering 8 GW of high voltage direct current ...

  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. [1]

  4. HVDC Cross-Channel - Wikipedia

    en.wikipedia.org/wiki/HVDC_Cross-Channel

    The HVDC Cross-Channel (French: Interconnexion France Angleterre IFA 2000) is the 73-kilometre-long (45 mi) high-voltage direct current (HVDC) interconnector that has operated since 1986 under the English Channel between the continental European grid at Bonningues-lès-Calais and the British electricity grid at Sellindge.

  5. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...

  6. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

  7. Submarine power cable - Wikipedia

    en.wikipedia.org/wiki/Submarine_power_cable

    500 MW capacity, 165 km DC Maritime Transmission Link between the Canadian province of Newfoundland and Labrador and the province of Nova Scotia. [ 29 ] British and Danish power companies ( National Grid and Energinet.dk , respectively) are building Viking Link , a 740 km cable to provide the two countries with 1,400 MW transmission by 2022.

  8. Mathematics of three-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Mathematics_of_three-phase...

    Another example is the generation of higher-phase-order systems for large rectifier systems, to produce a smoother DC output and to reduce the harmonic currents in the supply. When three-phase is needed but only single-phase is readily available from the electricity supplier, a phase converter can be used to generate three-phase power from the ...

  9. Western Interconnection - Wikipedia

    en.wikipedia.org/wiki/Western_Interconnection

    Interconnections can be tied to each other via high-voltage direct current power transmission lines such as the north-south Pacific DC Intertie, or with variable-frequency transformers (VFTs), which permit a controlled flow of energy while also functionally isolating the independent AC frequencies of each side.
