A gas discharge tube (GDT) is a type of electrical surge arrester that provides protection against electrical surges. The GDTs consist of two electrodes enclosed in an insulating tube filled with a gas. These devices are designed to protect against electrical power surges and electrostatic discharges (ESDs), which can induce excessive and damaging currents in electrical systems. GDTs are widely used in various applications, such as power protection for telecommunication systems, power switching systems, and the protection of electronic circuits and equipment.The VS450A-B is a type of GDT arrester which is suitable for various applications, such as point-of-use lightning or industrial surge protection. It has a stainless steel metal-oxide-varistor (MOV)-enclosed current limiting voltage spark gap. This feature helps limit the voltage load by redirecting the flow of electricity. The MOV provides reliable short-circuit protection and helps to dissipate the energy generated by severe over-voltage transients in modern transmission networks.The working principle of a GDT arrester is based on the arc-breakdown phenomenon. When a certain voltage is applied to the GDT, the air inside the gap ionizes, forming an arc. The arc will then be extinguished by a metallic oxide varistor (MOV) and the current will be automatically limited. This is how GDTs provide surge protection, as the MOV helps reduce the voltage to a safe level.The VS450A-B GDT arrester is designed for point-of-use lightning and industrial surge protection. It consists of a stainless steel MOV enclosed spark gap, an integrated varistor element, and a GDT. The MOV ensures fast response times during short-term over-voltage transients, and the varistor element provides reliable and effective ESD protection. The stainless steel gap has two electrodes that form an arc when a positive voltage is applied. The arc is then extinguished when a protective device is activated to limit the voltage and discharge the excess current. The VS450A-B GDT arrester offers a wide range of protection features. It is designed to provide superior protection against over-voltages, current surges, and lightning surges. It is also capable of disconnecting the protected equipment in the event of a short circuit. The VS450A-B can be used in applications for single-phase protection or three-phase systems. In conclusion, the VS450A-B GDT arrester is a reliable and reliable surge protection device designed for various applications. Its stainless steel MOV-enclosed spark gap and integrated varistor element provide superior protection against over-currents, transient over-voltages, and ESDs. The fast response times of the MOV and the ability to disconnect the protected system in the event of a short-circuit make the VS450A-B a reliable protection solution for various applications.
