Gas discharge tubes (GDTs) are arresters which have been designed and developed for overvoltage protection in power systems, electronic circuits, and other applications, where voltage surges and lightning strikes are frequent. GDTs are widely used in industrial, commercial and residential applications, to protect all types of delicate electronic equipment, to protect against power line disturbances and to provide continuous reliable protection. This article will focus on the application field and working principle of GDTs for 2037-09-A.

GDTs offer excellent protection against overvoltage surges, including those caused by lightning strikes and LV/HV switching operations. GDTs provide short-circuit protection even at very high currents, as well as lightning protection, line disconnection and isolation, and other features. GDTs are designed to automatically reset and remain operational even after repeated surges. GDTs are used in applications requiring a lot of current handling, such as in power plants, substations, laboratories, and broadcasting with high frequencies.

The working principle of GDTs is based on the discharge of electrons from a low breakdown gas-filled tube, also known as a spark gap, when an overvoltage is applied. When current flows through the GDT, the gas ionizes and breaks down, creating an electrical discharge or "arc." The arcing in the GDT is controlled in order to protect the system from the damaging surge. The GDT operates by conducting the power of the surge to the grounding system or to neutral, thus protecting the system from the damaging effects of the surge.

GDTs provide an ideal protection against voltage surges, as they can handle both low and high frequency surges and provide precise control of arcing conditions. GDTs are designed with an absorbent material or by adding a resistor which can absorb and dissipate energy during the surge. The absorbed energy is then dissipated to the grounding surface. GDTs are also designed to reduce voltage spikes and also the peak voltage to a safe level. GDTs are tested and certified for safety and reliability, ensuring a high level of protection for power systems.

GDTs can also be used to provide protection from harmonics and abnormal waveforms caused by switching and load demands. GDTs can protect against short circuits and other voltage-related disturbances, including line power failures, equipment malfunction, and transients caused by lightning. GDTs are also able to provide protection against radio frequency interference. GDTs can be configured to provide protection from a single line or multiple lines, depending on the application.

In conclusion, GDTs are a reliable and effective form of overvoltage protection, and are used in a wide variety of applications. GDTs offer a high level of protection against many different types of voltage disturbances, including lightning, short circuits, harmonics, and abnormal waveforms. GDTs are tested and certified for safety and reliability, and can be configured to provide protection from a single line or multiple lines. The working principle of GDTs is based on the discharge of electrons from a low breakdown gas-filled tube, creating an electrical discharge or arc, which is controlled in order to protect the system.
