What is the function of lightning arrester?

Protect electrical equipment : Lightning arresters are mainly used to protect electrical equipment from high transient overvoltages (such as lightning strikes, operating overvoltages, etc.). When the power system is struck by lightning or internal overvoltage, the arrester can act quickly to guide the overvoltage to the ground, thereby protecting the electrical equipment from damage.

Limiting the overvoltage amplitude : The arrester is connected in parallel at both ends of the protected equipment, and can quickly conduct when the overvoltage occurs, limit the amplitude of the overvoltage, and prevent the overvoltage from causing serious consequences such as insulation breakdown on the electrical equipment.

Cut off the power frequency continuous current : After the overvoltage, the arrester can also quickly cut off the power frequency continuous current to prevent the current from having a continuous impact on the system and ensure the stable operation of the power system.

Improve system reliability : The application of lightning arresters can significantly improve the reliability of the power system, reduce equipment failures and power outages caused by overvoltage, and ensure the continuity and stability of power supply.

Protect communication lines and equipment : In the communication system, the arrester also plays an important role. It can effectively protect communication lines and equipment from natural factors such as lightning and ensure the normal operation of the communication system.

Reduce maintenance costs : The effective application of lightning arresters can reduce equipment damage and maintenance costs caused by overvoltage, and reduce the overall maintenance cost of the power system.
