  2. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    The main attraction of a TN network is the low impedance earth path allows easy automatic disconnection (ADS) on a high current circuit in the case of a line-to-PE fault as the same breaker or fuse will operate for either L-N or L-PE faults, and an RCD is not needed to detect earth faults.

  3. Ground (electricity) - Wikipedia

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

    Since for the omnidirectional antennas used on these bands the Earth currents travel radially toward the ground point from all directions, the grounding system usually consists of a radial pattern of buried cables extending outward under the antenna in all directions, connected together to the ground side of the transmitter's feedline at a ...

    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).

    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.

    Such loops in the ground path can cause currents in signal cable grounds by two main mechanisms: Ground loop current induced by stray AC magnetic fields (B, green) Ground loop currents can be induced by stray AC magnetic fields [ 5 ] [ 7 ] (B, green) which are always present around AC electrical wiring.

    Main bonding connects "extraneous conductive parts" such as mains water / gas supply pipes, structural parts of buildings, communication cable sheaths, lightning protection systems etc., to the main earthing terminal. [14] These parts could otherwise introduce potentials that are different from the potential of the installation's earthing system.
