  2. Isolated ground - Wikipedia

    en.wikipedia.org/wiki/Isolated_ground

    The EG circuit includes all of the metal conduit, outlet boxes, and metal enclosures that contain the wiring and must be grounded to provide a safe return path in case of fault currents. The IG provides an insulated, separate ground path for the ground reference in electronic equipment, such as computers, hospital equipment, and audio equipment.

  5. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    In Japan building wiring uses TT earthing in most installations. In Australia, the multiple earthed neutral (MEN) earthing system is used, described in Section 5 of AS/NZS 3000. For an low-voltage (e.g. domestic) customer, this means TN-C-S, with the neutral connected to Earth multiple times between the supply transformer and the consumer ...

  6. Ground (electricity) - Wikipedia

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

    A distribution system insulated from earth ground may attain a high potential due to transient voltages caused by static electricity or accidental contact with higher potential circuits. An earth ground connection of the system dissipates such potentials and limits the rise in voltage of the grounded system.

  7. Grounding transformer - Wikipedia

    en.wikipedia.org/wiki/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.

  8. Single-wire earth return - Wikipedia

    en.wikipedia.org/wiki/Single-wire_earth_return

    Single-wire earth return (SWER) or single-wire ground return is a single-wire transmission line which supplies single-phase electric power from an electrical grid to remote areas at lowest cost. The earth (or sometimes a body of water) is used as the return path for the current, to avoid the need for a second wire (or neutral wire ) to act as a ...

  9. Ground and neutral - Wikipedia

    en.wikipedia.org/wiki/Ground_and_neutral

    Normal circuit currents flow only in the neutral, and the protective earth conductor bonds all equipment cases to earth to intercept any leakage current due to insulation failure. The neutral conductor is connected to earth at the building point of supply, but no common path to ground exists for circuit current and the protective conductor.
