1. Earth conductor
From the grounding terminal of electrical equipment to the connecting wire or conductor of the grounding device, or from the metal object that needs equipotential bonding, the general grounding terminal, the grounding summary board, the general grounding bar, and the equipotential bonding bar to the connecting wire or conductor of the grounding device.
2. Direct lightning flash
Lightning that directly strikes actual objects such as buildings, the ground or lightning protection devices.
3. Ground potential counterattack Back flashover
The lightning current passes through the grounding point or grounding system and causes the ground potential of the area to change. The ground potential counterattack will cause the potential of the grounding system to change, which may cause damage to electronic equipment and electrical equipment.
4. Lightning protection system (LPS)
Systems that reduce lightning damage to buildings and installations, including external and internal lightning protection systems.
4.1 External lightning protection system External lightning protection system
The lightning protection part of the exterior or body of a building (structure) usually consists of an air-termination device, a down conductor and a grounding device to prevent direct lightning strikes.
4.2 Internal lightning protection system
The lightning protection part inside a building (structure) usually consists of an equipotential bonding system, a common grounding system, a shielding system, reasonable wiring, surge protectors, etc., which are mainly used to reduce and prevent lightning current from being placed in the protection space. The electromagnetic effect produced.
