Gas Discharge Tube Arresters (GDT)

Gas Discharge Tube Arresters (GDT) are used to protect telecommunications and power systems from over-voltage surges caused by lightning or other electric faults. By providing an electrical pathway, GDT arresters can protect these systems from the catastrophic effects of a sudden surge in voltage.The working principle of GDT is based on the gas-filled capacitor. This is usually enclosed in a glass envelope and consists of two metal electrodes, separated by a thin insulating film. When a surge of electricity passes through the tube, the film breaks down, forming an electric arc from the cathode to the anode.The arc is then extinguished as the released gas cools and the current is stopped. This process is then repeated with each surge in electric current. As a result, GDTs can protect electrical systems from surges of as high as several hundred kilovolts.The application field of GDT is very wide. It is mainly used in telecommunications systems such as telephone networks, satellite networks and radio networks. It can also be used in power transmission systems and electric motors. In addition, GDTs are used in industrial, military and medical applications.The main advantages of GDTs are their low cost, low maintenance and their ability to provide effective surge protection in a wide variety of applications. In addition, GDTs are also very reliable and can be used in many hazardous environments where normal surge protection devices may not be suitable.GDTs are highly effective and efficient surge protection devices. It is important to note, however, that GDTs are not a substitute for other forms of surge protection devices, such as adjustable voltage suppressors, which may be required for certain applications.In conclusion, Gas Discharge Tube Arresters (GDT) are widely used in various telecom, power systems and medical applications for providing effective surge protection. GDTs are highly reliable and efficient and offer a low cost solution for protecting electrical systems from the potentially devastating effects of extended over-voltage surges.
