Gas Discharge Tube Arresters (GDT) are a type of electrical device that acts as a safety valve for high-voltage electrical systems. They are commonly used to protect switchgear, transformers, and other equipment from damage caused by electrical surges or lightning strikes. GDTs provide reliable protection from overvoltages and are an important component in any electrical system.GDTs are a type of surge-protection device that is composed of two electrodes which are connected by a dielectric. When an overvoltage or surge occurs in the system, a gas discharge will occur between the two electrodes, allowing the surge energy to be safely diverted away from the system. The two electrodes create a channel, and when a surge moves through the electrodes, it travels along this channel, providing a safe route of travel for the surge.The working principle of GDTs is based on the fact that when an electric current is applied to a wire, it forms an electric field, which is measured by the amount of force (voltage) applied to the wire. When a high voltage is applied to the GDT, the electric field created between the two electrodes accelerates electric particles, after which an avalanche breakdown occurs. This is when a spark occurs between the electrodes and a large quantity of ions are formed. These ions form a plasma-like channel between the two electrodes, allowing the surge to follow a safe path to ground.GDTs have a wide range of applications in various industries. In the telecom industry, they are used to protect switchgear and equipment from lightning surges. In the power sector, they are used to protect transformers and substations from power surges due to lightning strikes. In the medical field, GDTs are used to protect potentially explosive and sensitive medical equipment from damage caused by electrical surges. They are also used in applications such as radio broadcasting, computer hardware, and general-purpose switching.GDTs play an important role in protecting equipment from damage caused by electrical surges. They can be easily incorporated into existing electrical systems and their low cost makes them an attractive surge-protection option. GDTs are a reliable way to protect electrical systems from overvoltages and should be an essential component in all high-voltage systems.
