When it comes to grounding, what do people think of first is the grounding pole? In fact, grounding is a system, not a single existence.
Ground refers to an object that can supply or accept a large amount of electric charge and can be used as a good reference potential, generally referring to the earth, and is taken as a zero potential in engineering. The potential reference point in an electronic device is also referred to as "ground" but is not necessarily connected to the ground.
Connect some conductive parts of a power system or electrical device to the ground through a ground wire, usually referred to as a ground.
A metal conductor that is buried in the ground to provide a low-impedance path from the electrical device to the ground and that is in direct contact with the ground is called a grounding pole. Natural metal grounding poles are used for various metal members, metal pipes, metal well pipes, building structures, and equipment foundations that are used directly for contact with the earth.
A system consisting of grounding poles, total grounding terminals or grounding busbars and connecting conductors between them is called a grounding system (grounding device). Generally, the total grounding terminal or the grounding busbar is the potential reference point.
The conductor for connecting the grounding terminal of the electrical device to the total grounding terminal or the grounding busbar is called the grounding wire.
The sum of the ground and grounding systems is called the grounding system.
