  2. Isolated ground - Wikipedia

    en.wikipedia.org/wiki/Isolated_ground

    An isolated ground (IG) (or Functional Earth (FE) in European literature) is a ground connection to a local earth electrode from equipment where the main supply uses a different earthing arrangement, one of the common earthing arrangements used with domestic mains supplies.

  3. Groundbed - Wikipedia

    en.wikipedia.org/wiki/Groundbed

    Other grounding electrodes may include buried solid plates, or a grid of buried wires, where soil conditions do not favor driven ground rods. Buried metallic piping systems, well casings or the reinforcing bars of concrete slabs in contact with the earth have all been used as grounding electrodes.

  4. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    While the national wiring regulations for buildings of many countries follow the IEC 60364 terminology, in North America (United States and Canada), the term "equipment grounding conductor" refers to equipment grounds and ground wires on branch circuits, and "grounding electrode conductor" is used for conductors bonding an earth/ground rod ...

  5. Grounding resistance tester - Wikipedia

    en.wikipedia.org/wiki/Grounding_resistance_tester

    The analog grounding resistance tester is realized by four main blocks DC generator, rectifier, current and potential coil.The deflection of the pointer of the analog screen depends on the ratio of the voltage of pressure coil to the current of the current coil.

  6. Tieback (geotechnical) - Wikipedia

    en.wikipedia.org/wiki/Tieback_(geotechnical)

    In geotechnical engineering, a tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground. Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles , sheet piles, secant and tangent walls) to provide ...

  7. Ufer ground - Wikipedia

    en.wikipedia.org/wiki/Ufer_Ground

    The concrete enclosure also increases the surface area of the connection between the grounding conductor and the surrounding soil, which also helps to reduce the overall impedance of the connection. Ufer's original grounding scheme used copper encased in concrete. However, the high pH of concrete often causes the copper to chip and flake.

  8. Rebar spacer - Wikipedia

    en.wikipedia.org/wiki/Rebar_spacer

    A concrete spacer with a plastic clip in use Concrete spacers in a precast element Diaphragm wall block on rebar for a Diaphragm wall. A rebar spacer is a short, rod-like device used to secure reinforcing steel bars, or rebar, within cast assemblies for reinforced concrete structures. The rebar spacers are fixed before the concrete is poured ...

  9. Grounding kit - Wikipedia

    en.wikipedia.org/wiki/Grounding_kit

    Grounding kits for different diameters Part of a tin-plated ripple. Grounding kits / Earthing kits are composed of two main components, a clamp and a cable. The clamp will be screwed on a coaxial cable and in case of lightning strokes in the antenna installation, the voltage will be diverted over a ripple in the clamp with the combined cable and will be earthed / grounded by this way.
