Gas Discharge Tube Arresters (GDT) are devices that protect electronic and electrical equipment from high energy transient over voltages. GDTs are designed to mitigate the effects of electrical surges caused by lightning, power line transients, inductive load switching and similar power system transients. They are typically composed of a resistor, which restricts the flow of voltage, and a gas-filled tube, which is designed to break down and absorb electrical transients. GDTs are typically installed at the point of entry to the equipment to be protected, such as on the electrical panel of a home or business, as well as across the power line to the service entrance.

GDTs are composed of two components: an electric conductor and a dielectric gas-filled tube. The electric conductor is usually a metal wire or coil that is housed in a protective insulator or tube. The dielectric gas-filled tube is typically a high-voltage capacitor and it contains a gas mixture that has been optimized to react quickly to electrical surges and to store large amounts of energy. Therefore it is able to break down and absorb the surge energy without causing damage to the electric conductor.

The working principle of GDTs is based upon the ability of the gas mixture contained within the dielectric tube to break down electrical transients. This phenomenon is known as “dielectric breakdown.” When there is a high surge of energy, the gas mixture in the tube will ionize and become conductive. This allows the portion of the surge energy that exceeds the arrester’s holding voltage to be directed to ground. The resistor element contained in the device functions as a current-limiting device, helping to restrict the flow of surge energy.

GDTs are used in a variety of applications, including power distribution, telecommunications, computer networks, intelligent transportation systems, broadcast equipment, and consumer electronics. GDTs can be used to protect appliances, power tools, industrial motors, telecommunication equipment, and other electrical and electronic devices from electrical surges. They are also used to protect against power line transients, inductive load switching, and other sources of high energy transients. In addition, GDTs are often used in combination with a surge suppressor device and/or a surge protection device, in order to provide complete protection from high energy transients.

GDTs are reliable and relatively easy to install. They are designed to be maintenance-free and, in most cases, can be installed without any special tools. Additionally, GDTs can provide cost savings by reducing the need for other surge protection devices and wiring. GDTs are also cost-effective when compared to other surge protection devices, as they do not require frequent inspection or maintenance.

In conclusion, GDTs are a reliable, cost-effective, and easy-to-install device for protecting electronic and electrical equipment from high energy transient over voltages. They are composed of two components: an electric conductor and a dielectric gas-filled tube. The resistor element contained in the device functions as a current-limiting device, helping to restrict the flow of surge energy. GDTs are used in a variety of applications and offer a cost-effective way of protecting electrical and electronic devices from electrical surges.
