  2. War of the currents - Wikipedia

    en.wikipedia.org/wiki/War_of_the_currents

    The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s; arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting ...

  3. Electric power system - Wikipedia

    en.wikipedia.org/wiki/Electric_power_system

    An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area.

  4. Electric power distribution - Wikipedia

    en.wikipedia.org/wiki/Electric_power_distribution

    Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers . [ 1 ]

  5. Thomas Edison - Wikipedia

    en.wikipedia.org/wiki/Thomas_Edison

    The primary reason was that Edison Electric based their design on low voltage DC, and switching a standard after they had installed over 100 systems was, in Edison's mind, out of the question. By the end of 1887, Edison Electric was losing market share to Westinghouse, who had built 68 AC-based power stations to Edison's 121 DC-based stations.

  6. Split-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Split-phase_electric_power

    A split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the alternating current (AC) equivalent of the original Edison Machine Works three-wire direct-current system.

  7. History of electric power transmission - Wikipedia

    en.wikipedia.org/wiki/History_of_electric_power...

    These systems were replaced by cheaper and more versatile electrical systems, but by the end of the 19th century, city planners and financiers were well aware of the benefits, economics, and process of establishing power transmission systems. In the early days of electric power usage, widespread transmission of electric power had two obstacles ...

  8. Electrical grid - Wikipedia

    en.wikipedia.org/wiki/Electrical_grid

    Diagram of an electrical grid (generation system in red, transmission system in blue, distribution system in green) An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric ...

  9. Electric power industry - Wikipedia

    en.wikipedia.org/wiki/Electric_power_industry

    Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 35 kV with the use of transformers . [ 12 ]
