1) Ground
Any point's potential is conventionally taken as zero with respect to the earth or a conductive substance.
2) Grounding
Electrical connections are made to objects that can either supply or receive a large amount of electric charge (such as the ground, ships, or the metal shells of transportation vehicles, etc.).
3) (Electrostatic) Grounding
The measure of connecting a metal conductor (via a grounding electrode) to the earth electrically, so as to make the potential of the metal conductor close to that of the earth.
3) Grounding
A. Direct grounding or connection to the ground through a low-impedance path.
B. Connect to the ground through a wire or other conductor with a very small or almost zero resistance (impedance).
5) Soft Grounding
By applying sufficient impedance grounding, the current is limited to a level below the level of personal safety (typically 5mA). The impedance required for soft grounding depends on the voltage level that the personnel near the grounding point may be exposed to.
6) Direct grounding
A grounding method that connects the metal body to the earth through conductive connection.
7) Indirect grounding
A grounding method that enables objects other than metals to be electrically grounded by closely connecting the entire or part of their surfaces to a grounded metal body.
8) Electrostatic discharge grounding device
A public device, within the electrostatic discharge protection area, has an unfunctional component connected to it and is grounded.
9) Ground reference plane
A flat conductive surface with its potential being used as the common reference potential.
10) Electrostatic grounding connection system
The external channel through which the charges on an electrified body leak and dissipate to the ground.
11) Human body grounding
The measure of keeping the human body in a conductive connection with the earth by using conductive pads, conductive floors, conductive shoes or other grounding devices.
12) Ground (electrical) electrode
A conductor or a combination of several conductors that is buried in the ground to ensure good contact with the earth.
13) Ground voltage
The potential difference between the charged body and the ground (with the ground potential set to zero).
14) (Electrostatic) connection
The measure of connecting objects that do not have a good conductive path between them, so that they are generally at the same electrical potential.
15) Joining
A. Any fixed connection that enables electrical conductivity between two objects. This connection can be the direct contact between the conductive surfaces of the two objects, or a firm electrical connection installed between the two objects.
B. In electrical engineering, a method of connecting various metal parts together to achieve low-resistance electrical contact for both direct current and low-frequency alternating current.
16) Single-point grounding
Each circuit or shielding body has only one connection point to the ground. Ideally, a subsystem should be connected to the same grounding point. This method can prevent return current from flowing through the structure.
17) Connecting wires [strip, sheet]
A. A type of metal woven wire or metal strip [sheet] used for joining.
B. When it is impossible to maintain sufficient electrical contact between the components and the structure by other means, a metal woven wire or metal strip [sheet] is provided to offer the necessary conductivity between them.
18) Leakage Resistance
The equivalent resistance of an object when it is not charged, from the measurement point to the grounding connection system.
19) Leakage Current
The current that flows from the charged body to the ground through various leakage pathways.
20) Electrostatic Leakage Path
The process by which the static charges in the electrified area are dissipated through the interior and surface of the charged body.
21) Leakage Current
Any current that does not flow along the designated path can be found in these non-designated paths, which may include the earth, pipelines connected to the earth, and other metal objects or structures.
