  2. Ground and neutral - Wikipedia

    en.wikipedia.org/wiki/Ground_and_neutral

    Ground and neutral. A shorting bar connecting ground and neutral in Swiss industrial building (outlined in red). A hunk of copper is visible that is designed to be easily connected or disconnected from its place between two screws, rated for 600 A (as stamped on it). We also see the thick wires in standard colors (two yellow/green ground and ...

  3. Ground (electricity) - Wikipedia

    en.wikipedia.org/wiki/Ground_(electricity)

    Ground (electricity) A typical earthing electrode (left of gray pipe), consisting of a conductive rod driven into the ground, at a home in Australia. Most electrical codes specify that the insulation on protective earthing conductors must be a distinctive color (or color combination) not used for any other purpose.

  4. Electrical grid - Wikipedia

    en.wikipedia.org/wiki/Electrical_grid

    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 power transmission to carry power over long distances, and finally electric power distribution to customers.

  5. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    Electrical installations. An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the equipments conductive surface, for safety and functional purposes. [1] The choice of earthing system can affect the safety and electromagnetic compatibility of the installation.

  6. Three-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Three-phase_electric_power

    Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2] It is a type of polyphase system employing three wires (or ...

  7. Multipoint ground - Wikipedia

    en.wikipedia.org/wiki/Multipoint_ground

    A multipoint ground is an alternate type of electrical installation that attempts to solve the ground loop and mains hum problem by creating many alternate paths for electrical energy to find its way back to ground. The distinguishing characteristic of a multipoint ground is the use of many interconnected grounding conductors into a loose grid ...

  9. Grounding transformer - Wikipedia

    en.wikipedia.org/wiki/Grounding_transformer

    Grounding transformer. A grounding transformer or earthing transformer is a type of auxiliary transformer used in three-phase electric power systems to provide a ground path to either an ungrounded wye or a delta-connected system. [1] [2] Grounding transformers are part of an earthing system of the network.
