Gas Discharge Tubes (GDT) arresters are used widely in electrical applications for protecting equipment and components from lightning, line faults, and other transient electrical events. The basic principle of GDT is that when a voltage greater than a certain level called the threshold is applied across the terminals of the GDT, the displaced electrons in the gas will react with the gaseous molecules to form charged particles. These charged particles are then able to carry current, and when enough of them have been created, the GDT will light up, indicating a discharge.

Different types of GDTs can be used for different types of applications, such as residential installations, industrial installations, and military installations. The most commonly used type of GDT is the Standard-Reactive Platelet-Loaded Field (RPLF) arrester. The RPLF arrester is composed of two parts: the reactive platelet and the field. The reactive platelet is a layer of two or more specially designed plates that are separated by a layer of insulating material. The field is an array of metal turnings that serve to create an artificial air gap between the two plates. This air gap forms a capacitive element between the turnings and the plates, and it is this capacitive field that absorbs the energy of a surge and discharges a spark gap.

When a surge is applied to the reactive platelet, the energy is absorbed by the capacitive field. As the energy is absorbed, it orders the nitrogen molecules within the GDT, which creates a molecular chain and a spark gap. The spark gap allows the current to flow between the turnings and the plates. This effectively reduces the voltage, thus protecting the equipment or components connected to the GDT arrester.

In addition to protecting equipment and components from transient electrical events, GDTs are also used to limit incoming lightning voltage from ground or direct lightning. This is done by creating a discharge gap, and is referred to as a spark gap arrestor. The spark gap arrestor is specifically designed to open when the incoming voltage from lightning exceeds the threshold. When the spark gap opens, it allows the energy from the lightning to dissipate safely into the surrounding ground.

The GDT arrester is an effective and reliable way of protecting equipment and components from lightning, line faults, and other transient electrical events. Its two-part design makes it easy to install, and the charged particles created by the system effectively reduce the incoming voltage, protecting the equipment from damage. The spark gap arrestor also provides effective protection from ground or direct lightning.
