Introduction to Gas Discharge Tube Arresters (GDT)

Gas discharge tube (GDT) arresters are devices used mainly for protection from overvoltage. The name “arresters” is derived from their ability to limit electrical flow, by stopping arcing or discharging excessive energy caused by a fault or surge. The GDT arrester is made up of a non-conductive gas-filled capsule within a conductive metal housing. These components are generally connected in parallel between two points of a DC power source or in series in an AC circuit, with one end earthed.

Working Principle of GDT Arresters

The working principle of GDT arresters is fairly straightforward. When the voltage in the power line is within the normal range, the GDT remains in its ‘non-conductive’ state, allowing the current to flow unrestricted. However, when the voltage level in the power supply exceeds a certain level, or an electrical surge occurs, the non-conductive gas inside the GDT starts to conduct. This creates an electrical pathway between the two terminals, allowing a large amount of current to be released in a very short amount of time. Before this current surpasses a certain level, and with the help of the grounded connection, the GDT provides a protective circuit that limits the current and voltage to within safe levels, thus preventing the connected devices from damage.

Applications For GDT Arresters

GDTs are mainly used in industrial applications, such as power transmission systems, rotating machinery, and high voltage transmission lines. They are especially useful in areas prone to extreme weather conditions, like lightning storms, as they provide a reliable and effective protection against any electrical surges caused by such disasters. GDT Arresters are also widely deployed in many other industries, including automotive, marine, avionics, and medical applications. Applications where the size of the arrester is a major deciding factor also benefit from the GDT. Due to their small size and easy installation, they are also ideal for use in homes and commercial buildings.
