A chassis ground is a link between different metallic parts of a machine to ensure an electrical connection between them. [1] Examples include electronic instruments and motor vehicles. Usages
A grounding resistance tester also called an earth tester is a soil resistance measuring instrument. It is used for sizing and projecting grounding grids.

PE and N are entirely separate conductors. If a neutral conductor is provided, and if the point from which the transformer connects to Earth is the neutral-star-point, then PE and N conductors will be connected at this one and only point within the system. Note that the armoring of the supply cable is commonly used as the PE conductor between ...
A multipoint ground system is more complicated to install and maintain over the long term, and can be more expensive to install. Star topology systems can be converted to multipoint systems by installing new conductors between old existing ones. However, this should be done with care as it can inadvertently introduce noise onto signal lines during the conversion process. The noise can be ...
Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. Wiring practices that protect against ground loops include ensuring that all vulnerable signal circuits are referenced to one point as ground. The use of differential signaling can provide rejection of ground-induced interference. The removal ...
It is used as a grounding transformer, creating a missing neutral connection from an ungrounded 3-phase system to permit the grounding of that neutral to an earth reference point; to perform harmonic mitigation, as they can suppress triplet (3rd, 9th, 15th, 21st, etc.) harmonic currents; [2] to supply 3-phase power as an autotransformer ...

IG does not break ground loops, which can damage equipment like computers, printers, etc.. Interconnected computer equipment often benefits from single-point grounding. IG is only used with special equipment that requires it. The IG is typically insulated and separate all the way back to the point of earth grounding rod outside of the building.
