Gas Discharge Tube Arresters (GDT)

A Gas Discharge Tube Arrester (GDT) is a type of surge arrester that is used to protect electrical systems from the damaging effects of electric current surges. These GDTs are normally rated in kilovolts (kV) and typically range in size from 5kV to 25kV.GDTs are commonly used in the telecommunications industry, power generation, power transmission, and industrial applications. GDTs are designed to provide protection against voltage surges in the form of lightning strikes, short-circuits, and other electrical disturbances.A GDT consists of a metal tube that is filled with a gas mixture that consists of both noble gases and elements, such as sulfur hexafluoride (SF6). The main components of a GDT are the electrodes, the core, and the gas mixture.The core of a GDT is a metal core that is made of an alloy that is specifically designed to conduct electricity. The core carries the charge that is generated from an electrical surge.The electrodes of a GDT are specially designed to conduct electrical energy. They are placed at the ends of the metal tube and are connected to the core.The gas mixture inside the metal tube of a GDT acts like an insulator. When an electric surge passes through the tube, the gas molecules within the gas mixture begin to break down and create a plasma. This plasma is what carries the electrical current away from the system, protecting it from damage.The 2003-47-SM-RPLF application field and working principle of GDTs are relatively simple. GDTs protect systems from lightning strikes, power surges, and other electrical disturbances. They work by conducting the electrical current away from the system before it can cause any damage. This is done by creating a plasma with the gas mixture inside the metal tube. The plasma carries away the excess charge from the system, protecting it from any damaging effects.GDTs are becoming increasingly popular due to their ease of installation and maintenance, as well as their high level of protection. GDTs are used in a variety of applications, from telecommunications systems to power generation and transmission. GDTs are an important part of any systems electrical protection equipment.
