  2. Grounding resistance tester - Wikipedia

    en.wikipedia.org/wiki/Grounding_resistance_tester

    When measuring earth resistance with an instrument, it is important to know some of its basic characteristics in order to accurately measure the soil resistance and to properly size the grounding installation. Most importantly, the range of resistance the device measures. Usually the range is three or four degrees.

  3. Ground continuity monitor - Wikipedia

    en.wikipedia.org/wiki/Ground_continuity_monitor

    A GCM or ground continuity monitor (also called a ground integrity monitor or ground continuity tester) is an electrical safety device that monitors the impedance to ground of a temporary electrical circuit and can provide indication (or protective trip) in the event impedance rises to an unsafe value. A GCM is either an external testing device ...

    en.wikipedia.org/wiki/Earthing_system

    In such a scenario current will take any alternate path available, and since extraneous-conductive-parts like water and gas pipes should be bonded to an installation's earthing, and the earthing is tied to the neutral, neutral current can still flow via the Earth, potentially passing through neighbouring properties (if their neutral is still ...

    en.wikipedia.org/wiki/Plumbing_drawing

    A plumbing drawing, a type of technical drawing, shows the system of piping for fresh water going into the building and waste going out, both solid and liquid. It also includes fuel gas drawings. Mainly plumbing drawing consist of water supply system drawings, drainage system drawings, irrigation system drawings, storm water system drawings. In ...

  6. Continuity test - Wikipedia

    en.wikipedia.org/wiki/Continuity_test

    In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path.

  7. Ground (electricity) - Wikipedia

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

    This varies widely; marshy ground or ponds, particularly salt water, provide the lowest resistance ground, while dry rocky or sandy soil are the highest. The power loss per square meter in the ground is proportional to the square of the transmitter current density flowing in the earth.
