Terminology Explanation of Electrostatic Grounding
****Hard Grounding:** Connecting an object directly to the earth or through a low-impedance connection.
**Soft Grounding:** Connecting an object to the earth through a sufficiently high impedance to limit the current to a safe level in the event of an electric shock.
**Direct Grounding:** Conductively connecting a metal conductor to the earth, bringing the conductor's potential close to the earth's potential.
**Indirect Grounding:** Connecting all or part of the surface of an external electrostatic conductor or subconductor to the grounded metal conductor as the grounding electrode.
**Bridge Grounding:** Structurally fixing two or more insulated metal conductors together using mechanical or chemical methods to create a low-impedance path for power flow before grounding.
