High Surge Currents: Imax=10kA(8/20μs)
The Lightning Surge Arrester is a critical protective device designed to safeguard electrical systems and equipment from lightning-induced surges and overvoltage damage. By efficiently diverting high surge currents to the ground, it prevents harmful voltages from penetrating electrical networks, ensuring system stability and equipment longevity.
This device operates using Gas Discharge Tube(GDT), which quickly respond to sudden voltage spikes by transitioning from a high-resistance state to a conductive state. The surge current is safely discharged through the grounding system, preventing damage to sensitive components.
The Lightning Surge Arrester can be classified into three types based on its applications:
- High-voltage protection for power systems, including generators and transformers.
- Low-voltage distribution systems to protect switchgear, power cables, and industrial equipment.
- Terminal and electronic devices such as computers, communication systems, and home appliances.
Lightning surge protector
The lightning surge protector, also known as a lightning arrester, is a device used to protect power systems and electrical equipment from lightning strikes and overvoltage damage. It quickly diverts lightning currents to the ground, preventing intrusion into equipment and ensuring the stable operation of power systems while avoiding damage caused by overvoltag
Working Principle
Gas Discharge Tube(GDT): When the system experiences overvoltage, the Gas Discharge Tube(GDT) quickly conducts, dispersing the overvoltage through the grounding circuit into the ground. Conductor Principle: By using conductors connected to lightning currents, the current is directed to the ground, protecting equipment and systems from overvoltage. Structural Design: The surge protector typically consists of a Gas Discharge Tube(GDT), conductors, and grounding wires.
Classification
Lightning surge protectors can be categorized based on different characteristics and applications: Category 1: Designed to protect high-voltage equipment in power systems, such as generators and transformers. Category 2: Used for low-voltage distribution systems and large electrical equipment, such as low-voltage switchgear and power cables. Category 3: Protects terminal devices and electronic equipment, such as computers and communication devices.
Installation and Maintenance
Installation Location: Lightning surge protectors should be installed at the entry and exit points of the equipment or system to be protected. This positioning minimizes the impact of overvoltage on the equipment, ensuring effective protection and reducing potential damage caused by lightning strikes or electrical surges. Proper placement is critical for optimal performance.
