What is protective grounding, surge proof grounding, and ESD grounding? What’s the difference?

 

There are three types of protective grounding:

 

Protective grounding: refers to grounding the exposed conductive part of the electrical equipment in the grounding protection system.

 

Lightning protection grounding: In order to prevent the lightning electrical system and equipment, as well as the elevated metal facilities and buildings, structures caused by the lightning protection device, lightning current can be discharged into the ground smoothly when the lightning protection device is grounded. (such as grounding of flash and arrester)

 

Antistatic grounding: To prevent the static electricity generated during the operation of the electrical system or equipment from harming people, animals, and property, and to smoothly import the harmful static electricity into the ground, ground the site where the static electricity is generated.

 

The above is the difference between protective grounding, surge proof grounding, and anti-static grounding.
