Gas Discharge Tube arresters (GDT) are electrical components used for protecting electrical systems by limiting overvoltages caused by transient phenomena. They are composed of a spark gap filled with a gas or vacuum, and an insulating member that supports the gap. Gas Discharge Tube arresters (GDTs) have been used since the early 20th century and have become an essential element for many electrical systems and applications.

GDTs have a wide range of applications, from domestic to industrial, and from telecommunications to medical. Most GDTs are used for protection against lightning, but they are also used for protection against electrostatic discharge, signal interference, and overvoltage disturbances in power grids.

In order to understand the working principle of GDTs, it is important to first understand how the spark gap works. A spark gap is an area of air limited by usually two electrodes. When an excess charge accumulates between the electrodes, the air around them breaks down and a spark is created. This absorption of electric energy causes a current to flow through the spark gap. The current is then transferred to a capacitor or transformer, which can be used to suppresses, redirect or absorb the excess charge.

This is how the GDT protects electrical systems. When an overvoltage occurs, the spark gap breaks down, allowing the excess charge to be transferred to the capacitor or transformer. The electric current, absorbed by the gap, dissipates in the form of heat.

In terms of GDTs\' application field, they are used mainly in the protection of communication lines, telecommunication equipment and power distribution systems. One of the major advantages of using GDTs in such application fields is that they have a low serial resistance and thus offer a low load on the system.

Moreover, GDTs can also be used in a variety of other applications, such as surge protector devices for computers and voltage regulator systems in motor vehicles. In recent years, they have been increasingly used in the protection of sensitive electronic components and circuits, which require additional protection during a surge or excessive voltage.

To summarize, Gas Discharge Tube arresters (GDTs) are an essential component of many electrical and electronic systems. They are used mainly in the protection of communication lines, telecommunication equipment and power distribution systems and have a wide range of other applications. By limiting overvoltages, GDTs help reduce the risk of damaging electrical systems and equipment, thus ensuring a safe and efficient operation.
