Gas Discharge Tube Arresters (GDTs) are an important component in the lightning protection system used in various industries such as information technology, communications, building and construction, automotive, aerospace, and defense. GDTs are designed to protect systems and equipment from high-voltage surges by providing an electrical barrier. They are used in series to protect an electrical circuit from transients, such as lightning strikes, surges, and electromagnetic intrusions caused by the sun\'s radiation.

In particular, 2027-47-A GDTs are designed to protect against overvoltages caused by Lightning (Bolt voltage) and Electric Noise (induced voltages). They are capable of withstanding high voltages up to 10 kV/μs, and feature low voltage specific and linear current characteristics. This GDT is made up of a two-part assembly, the gas discharge tube (GDT) and a spark gap. The GDT works by providing an electrical barrier for the system, which breaks down and starts conducting during an overvoltage condition, thus discharging the excess energy.

The 2027-47-A GDT has a gas discharge tube that is filled with a special natural gas and a spark gap that is filled with neutronium gas. The spark gap creates an ionization field and sets off a spark when the voltage exceeds a certain threshold. This ionization zone increases the voltage at which the spark gap starts to conduct. This is the principle of operation of the GDT – it works by creating an ionization channel that protects the system from high voltage spikes or transient energy.

The 2027-47-A GDT features an adjustable voltage clamping range that enables it to be customized to the needs of the system. This feature prevents unnecessary voltage spikes and helps to protect sensitive components. It also acts as a test port, allowing the system protection technician to check the performance and adjust the settings if necessary.

2027-47-A GDTs can be used in a variety of different applications, from power distribution systems to telecommunications networks. They are also used in aerospace and military applications for protection from high-voltage events. Additionally, they can be used in residential, commercial and industrial settings for lightning protection, surge protection and noise protection.

In conclusion, the 2027-47-A GDT provides a reliable and cost-effective solution for overvoltage protection in many different industries. Its adjustable voltage clamping range and spark gap give it an advantage over other GDTs, allowing it to be adjusted to specific applications. Its low voltage characteristic makes it suitable for use in sensitive systems and its ability to withstand high voltage transients makes it ideal for protection from high energy events such as lightning strikes.
