Surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When sharp spikes in current or voltage occur in electrical circuits or communication lines due to external interference, the surge protector can conduct and分流 within an extremely short time, thus avoiding damage to other equipment in the circuit caused by surges. 1. Air-termination system
Metal objects and structures designed for direct lightning strike reception or absorption, such as lightning rods, lightning conductors (wires), lightning nets, etc.

2. Downlinenductor system
Metal conductor connecting the connector to the grounding device.
3. Earth Termination System
Total of grounding bodies and grounding conductor connections.
4. Earth electrode
Metal conductors embedded directly into the ground and in direct contact with the earth. Also known as grounding electrodes. Various metal structures, facilities, pipelines, and equipment in direct contact with the earth can serve as grounding bodies, referred to as natural grounding bodies.
5. Earth conductor connection
Connection wires or conductors from the grounding terminal of electrical equipment to the grounding device, or from metal objects requiring equipotential bonding, main grounding terminal, grounding汇总 board, main grounding busbar, and equipotential bonding busbar to the grounding device.
6. Direct Lightning Flash
Direct lightning strikes on actual objects such as buildings, the earth, or lightning protection devices.
7. Ground Potential Counter Flashover
Ground currents passing through the grounding point or grounding system cause a change in ground potential in the area.反击 in ground potential can lead to changes in the potential of the grounding system, potentially causing damage to electronic and electrical equipment.
8. Lightning Protection System (LPS)
Systems to mitigate damage from lightning to protective targets such as buildings and equipment, including external and internal lightning protection systems.
8.1 External Lightning Protection System
The lightning protection component of the exterior or structure of a building, typically consisting of a lightning rod, down conductor, and grounding system, is designed to prevent direct lightning strikes.
8.2 Internal Lightning Protection System
The lightning protection component within a building typically consists of an equipotential bonding system, a common grounding system, a shielding system, proper wiring, and surge protectors, primarily designed to reduce and prevent the electromagnetic effects produced by lightning currents within the protected space.
