What is the difference between lightning protection grounding and other grounding devices

1. Lightning protection grounding refers to the grounding of lightning protection facilities (such as lightning rod, lightning strip, lightning network and lightning arrester). 2. Foundation Grounding refers to using the reinforcement mesh in the underground foundation of the building as the grounding body to replace the artificial grounding electrode. 3. Joint grounding mode: the joint grounding mode is also called single point grounding mode, that is, all grounding systems share a common "grounding". 4. Protective grounding: in order to ensure personal safety and prevent indirect electric shock, the exposed conductive part of the equipment is grounded, which is called protective grounding. There are two forms of protective grounding: one is that the exposed conductive parts of the equipment are directly grounded through their respective grounding protection wires; The other is that the exposed conductive part of the equipment is grounded through a common protective wire.
