1) Ground
The potential of any point is conventionally taken to be ground or conductive material.
2) Ground
Electrically connected to objects that can provide or accept a large amount of charge (such as on the ground, ship or vehicle metal enclosure, etc.).
3) (static) grounding
Measures to electrically connect the metal conductor (through the ground electrode) to the ground, so that the potential of the metal conductor approaches the ground potential.
4) Ground
A. Connect directly to ground or ground through a low impedance.
B. Connect to ground through a wire or other conductor with little or almost zero resistance (impedance).
5) Soft ground
Ground with sufficient impedance to limit the current to a personally safe level (typically 5MA). The impedance required for soft grounding depends on the voltage level that people close to the ground point may touch.
6) Direct ground
A ground connection that electrically connects a metal body to the ground.
7) Indirect ground
In order to ground objects other than metal statically, all or part of its surface is in close contact with a grounded metal body.
8) Electrostatic discharge grounding device
A public device where no devices connected to the device in the ESD-protected work area are grounded.
9) Ground reference plane
A flat conductive surface whose potential is used as a common reference potential.
10) Electrostatic ground connection system
The charge on the charged body leaks and dissipates to the ground and leads to the outside world.
11) Human body grounding
Measures to keep the human body and the ground in a conductive state by using conductive pads, conductive ground, conductive shoes, or other various grounding appliances.
12) Ground (electrical) electrode
A conductor or a combination of several conductors buried in the ground so as to make good contact with the ground.
13) Voltage to ground
The potential difference between the charged body and the ground (set the ground potential to zero).
14) (static) connection
A method of electrically connecting objects that do not have a good conductive path to each other so that they are at substantially the same potential.
15) Lap
A. Any fixed combination that makes two objects have conductivity. This combination can be a direct contact between the conductive surfaces of two objects, or it can be a strong electrical connection between two objects.
B. In electrical engineering, a method of connecting various metal parts together so that they exhibit low resistance electrical contact to DC and low-frequency AC currents.
16) Single point ground
Each circuit or shield has a ground connection with only one connection point to ground. Ideally, a sub-system is only connected to the same ground point. This method can prevent the return current from flowing in the structure.
17) Tap wiring [strip, sheet]
A. A kind of metal braided wire or metal strip [piece] for overlap.
B. A metal braided wire or metal strip [sheet] that provides the necessary conductivity between components and structures when sufficient electrical contact cannot be maintained by other methods.
18) Leakage resistance
The equivalent resistance of the object from the measured point to the ground connection system when the object is not charged.
19) Leakage current
Refers to the current that the charge on a charged body leaks to the earth through various leakage paths.
20) Static Leakage Channel
The path by which the static charge in the charged area leaks through the interior and surface of the charged body.
21) Stray current
Any current that does not follow a designated path. These unspecified paths can be the earth, pipelines connected to the earth, and other metal objects or structures.
