Gas Discharge Tube (GDT) arresters have become a vital component in a variety of industries, from power transmission to telecom networks. As the need for more reliable power systems increases, GDT arresters provide an efficient and cost-effective solution to protect sensitive material and components in an electric system from voltage surges. GDTs are also known as spark gap arresters, lightning arrestors, or surge arrestors. In this article, we’ll discuss the 2097-220-DLF application field and working principle of gas discharge tube arresters.

What is a Gas Discharge Tube Arrester (GDT)?

A Gas Discharge Tube arrester (GDT) is an over-voltage protection device designed to protect sensitive equipment from power transients, high frequency noise, and other over-voltage conditions. GDTs are composed of a dielectric tube filled with an inert gas, such as nitrogen or argon, and connected with a metal electrode. When subjected to over-voltage, the GDT limits the surge current by creating a spark gap between the electrodes. This gap causes the arrester to reduce the over-voltage levels to safer limits.

What is 2097-220-DLF Application Field?

Gas Discharge Tube Arresters (GDTs) are used in many different industries, and they can be found in power transmission lines, communication networks, telecommunications systems, and industrial control units. Generally, they are applied in power transmission systems to reduce transient voltages on communication lines and telephone systems. They can also be used to protect electrical equipment in industrial plants and other environments.

The 2097-220-DLF Application Field is an important one when it comes to selecting the right surge protection device. It is a device with a nominal voltage of 2.4kV and an impulse withstand voltage of 20.97kV. The device can be used for protecting sensitive electronic equipment, such as computer, telecommunications, radio, and TV systems. This arrester can also be used for lightning surge protection applications.

Working Principle of GDT Arresters

The working principle of GDT arresters is based on the spark gap effect. When subjected to a transient over-voltage, sparks develop between the electrodes within the GDT creating a spark gap. This spark gap limits the surge current by allowing the over-voltage energy to be dissipated by the spark gap. In this way, the GDT arrester reduces the over-voltage levels to safer levels.

The spark gap effect of GDTs can be further enhanced by using a combination of materials such as mica, ceramic, or other insulating materials. This helps to minimize the breakdown voltage and provides an effective mechanism for the over-voltage energy to be dissipated. Additionally, the spark gap effect can be further enhanced by changing the pressure of the gas within the GDT.

GDT arresters can be divided into two main types - the electromagnetic protective device (EMPD) and the over-voltage suppressor (OVS). The former is designed to reduce the surge and protect the electrical circuit while the latter is designed to limit the rise in voltage beyond the predetermined levels.

Conclusion

The 2097-220-DLF application field and working principle of gas discharge tube arresters are explained in this article. GDTs are typically used in power transmission and communication systems to reduce transient voltages on communication lines and telecom systems. Additionally, they are also used in industrial control units and other environments. GDT arresters protect sensitive electronic equipment from over-voltages by limiting the surge current with the spark gap effect. They can also be enhanced using a combination of materials. This article has provided a basic understanding of GDT arresters and their application.
