Gas discharge tube arresters (GDT) are semi-conductor devices used to protect circuits from harmful surge voltages created by lightning or other transient signals. They are designed to divert the surge energy to the ground, thereby protecting downstream components connected to the protected circuit. GDTs have rapidly become an industry standard protecting against voltage surges, which can damage, destroy or disrupt a wide range of electronic equipment and industrial machinery.

A modern GDT works on principle similar to that of a Zener diode. The device has two electrodes, a cathode and an anode which are separated by a gas-filled tube held in neutral pressure. Above a certain pressure, which is set by the user, an internal arc is created and the device rapidly discharges the surge energy to ground. This provides effective protection from the harmful voltage surges.

GDT’s have a wide range of application fields. They are used in industrial and commercial electronics, including power, process control, communications, and medical equipment. They are also used in the automotive industry, providing voltage surge protection for vehicle electronic systems and providing power for numerous sensors. GDTs are also used in telecommunications systems, providing suitable protection for telephone lines and computers. In addition, GDTs are also common in domestic applications, providing protection for electrical systems in the home.

The working principle of a GDT is fairly simple. The device consists of two terminals, a cathode and an anode, which are separated by a tube filled with a special gas. In the event of a voltage surge, the neutral pressure of the tube is exceeded and an arc is created which rapidly discharges the surge energy to the ground. This protects downstream components connected to the protected circuit as well as providing protection from further voltage surges. In addition, GDTs also provide steering protection, which is important when running circuits from multiple sources.

To conclude, gas discharge tube arresters (GDT) are designed to protect circuits against voltage surges caused by lightning or other transient signals. They have a wide range of application fields, including industrial and commercial, automotive and telecommunications systems. The working principle of a GDT is fairly simple and effectively discharges the surge energy to ground, providing downstream protection from further potential voltage surges.
