Gas Discharge Tube (GDT) Arresters are devices that provide protection against various electrical and electronic threats including short-term over-voltages, lightning, and static electricity. They are commonly used in residential, industrial, and commercial applications to guard against equipment damage caused by power surges or cross voltage.

GDT Arresters are composed of a gas filled tube (or gas charged tube) along with a triggering mechanism and a spark gap. The purpose of the tube is to conduct high voltage electricity, while providing a low resistance path for lightning or surge currents. The triggering mechanism allows the internal electrodes inside the tube to be connected when a particular voltage is reached, by breaking or making the connection with the GDT. This triggers the spark gap which acts as a safety valve, allowing additional surge current to be diverted away from sensitive equipment.

In most cases, GDT Arresters are designed to redirect high-voltage electricity away from vulnerable systems. They serve to limit electrical surges by providing a pathway for their discharge, thus preventing damage to sensitive components. The GDT arrester becomes the weaker link in the electrical system, absorbing or dissipating excess current before it can reach sensitive components.

The working principle of a GDT arrester is based on the concept of gas ionization. When a sufficiently high voltage is applied, the hydrogen gas in the GDT is ionized which forms a conductive path between the electrodes inside the tube. This path reduces the resistance so that the surge current can be diverted safely. The gas can then recombine and the tube can go back to its normal state.

GDT Arresters are widely used in many industries and applications, such as energy distribution, telecommunications, industrial electronics, home appliances, and industries with hazardous environments. They are also used in power transformers, solid state rectifiers, motor controllers, electronic equipment, and circuit breakers.
