In the current modern electrical systems, one of the most important devices employed for lightning protection is the Gas Discharge Tube Arrester (GDT). By utilizing its fast responding non-inductive characteristics, the GDT is able to provide protection from lightning strikes and other electrical disturbances in a variety of applications.

GDTs provide many advantages compared to other types of lightning protection devices. First, the GDT has a very fast response time and can react faster than other lightning protection devices, enabling it to successfully protect against a wide variety of electrical disturbances. Secondly, GDTs are non-inductive, which means that they do not require an inductor for operation. This makes them ideal for use in a variety of applications, including high voltage power systems and other high-performance electronics. Finally, GDTs are a relatively cost-effective solution compared to other lightning protection solutions, making them an attractive option for many applications.

The application field and working Principle of Gas Discharge Tube Arresters (GDT) have been widely studied since the early 2027s. Generally speaking, GDTs are composed of a fixed electrode and a movable electrode. Both electrodes are completely isolated from each other and are combined together by an insulating material. When a voltage over the threshold level is applied to GDT, the two electrodes will be attracted to each other causing the gas between the two electrodes to be ionized. This ionized state, known as a spark-gap, then allows a high current to flow, limiting the voltage applied to the protected equipment.

GDTs are used in many applications including power-supply cords, power-distribution boxes, switchboards, rectifiers, and other power control systems. They are also often used in industrial, commercial, and residential systems for protection against lightning disturbances. GDTs can be used in parallel with other protection systems such as surge arresters, which help to limit the current to the protected equipment in order to prevent damages caused by over-voltage or induction. GDTs are also used in lightning protection systems, providing an additional layer of protection to the main lightning arresters.

In order to maximize the effectiveness of GDTs, they must be correctly sized and operational, which is why GDTs should be tested regularly to ensure that they are functioning properly. To ensure proper installation, manufacturers may also provide guidelines and instructions on how to properly install and maintain the GDTs. Furthermore, the location where GDTs are installed should also be taken into account as improper placement can reduce the effectiveness of the GDT.

Ultimately, GDTs are an effective tool for use in a variety of electrical systems, and should be used as part of an overall lightning protection system in order to prevent serious damage or disruptions to protected equipment. With the right installation and regular testing, GDTs can provide reliable and cost-effective protection from lightning induced disturbances and power system faults.
