Gas Discharge Tube (GDT) arresters are surge protective devices used to protect electrical systems, components, and personnel from damaging transient overvoltage produced by lightning, switching operations, and other sources. GDT arresters have been used for many decades and are a well-established form of overvoltage protection. In this article, we will discuss the application field and working principle of 2035-15-C GDT arrester.

Applications

The 2035-15-C GDT arrester is designed for use in low voltage (up to 1000 V) power systems. It is most commonly used in residential and commercial buildings as well as in industrial applications. It is used to protect electrical systems from damaging transients caused by lightning strikes, switching operations, and other sources of overvoltage. It can also be used as a backup for other forms of protection in case of failure or malfunction of the primary protection.

Construction

The 2035-15-C GDT arrester is composed of a metal tube containing gas and two electrodes connected to the ends of the arrester. The gas is either argon or nitrogen and the electrodes are made of either zinc or aluminum. The gas is used to create a high resistance path between the electrodes that can temporarily store the energy in a high-energy spike. In the event of an overvoltage, the gas arcs over and dissipates the surge energy before it can damage the protected equipment.

Working Principle

The working principle of a GDT arrester is relatively simple. When an overvoltage occurs, a high-energy spike is created and the GDT arrester acts as a “safety valve,” dissipating the energy before it can damage the protected equipment. The gas inside the arrester acts as the medium through which the energy is dissipated. As the spike is conducted through the gas, it creates an arc that is limited by the electrodes. The arc then dissipates the energy into the surrounding air, protecting the equipment from the surge.

Advantages of GDT Arresters

GDT Arresters offer a number of advantages compared to traditional overvoltage protection systems. They are compact and lightweight, require little or no maintenance, and can be quickly and easily installed. They are also highly reliable and provide excellent protection from transient overvoltages.

Conclusion

The 2035-15-C GDT arrester is a reliable and effective form of surge protection for low voltage power systems. It is relatively simple to install and requires little or no maintenance. It is compact and lightweight, and is highly effective in protecting equipment from transient overvoltages.
