Gas Discharge Tube Arresters (GDT)

Gas Discharge Tube Arresters (GDT), commonly known as gas surge protectors, are designed to protect electrical and electronic devices against transient overvoltage and lightning strikes. GDTs are a type of voltage-limiting device, which uses a bulb filled with a gas which absorbs electrical energy from surges and lightning strikes, dissipating the energy as heat. This act of dissipating electrical energy keeps any spikes or damage from occurring to the protected device. GDTs are used to protect circuits in telecommunications and other systems all over the world from lightning and other transient overvoltage runs.The distant surge protector, commonly referred to as the 2027-09 BLF application, is a form of GDT. The device works by providing a path for a surge to be diverted away from the protected device. When used, the device acts as a capacitor, thus limiting the voltage which is fed into a protected device. It is also designed to provide a low series resistance to the surge, meaning that GDTs can absorb larger individual surge voltages.GDTs can come in a variety of sizes to fit the specific application, and an individual GDT can have multiple paths or configurations in order to help absorb and dissipate multiple surges. Furthermore, they are designed in such a way that they can all work in conjunction with one another in order to provide multiple levels of surge protection within a single space. The 2027-09 BLF application, for example, is made up of multiple interconnecting GDT paths, whose aim is to withstand the surge and divert its energy to the ground. The GDTs are connected in such a way as to induce a low current impedance at the point of connection, thus providing the extra surge protection.When making a GDT selection, it is important to consider both the voltage level and the surge rating of the device. Voltage levels are determined by the application, while the surge rating determines the amount of energy which the GDT can absorb during an overload event. ARCON, the company which produces 2027-09 BLF application, provides GDTs ranging from 4 to 60 kilovolts with a range of surge ratings. With the right combination, one can create a reliable surge protection solution for any application.Protection levels of GDTs can be enhanced further by incorporating them into solutions which include other technologies, such as MOVs or polymeric SPDs. These technologies, when used in conjunction with GDTs, create an effective surge protection solution that can last for many years, even in the most demanding of environments. Such solutions provide reliable and sustained protection, while at the same time ensuring that the protected device is able to function safely and reliably.In conclusion, GDTs are just one part of an overall electrical surge protection system. GDTs, while providing effective and reliable protection in most cases, may not be suited to all applications. That said, when used in combination with other surge protection technologies, such as MOVs and SPDs, GDTs can provide reliable and sustained protection against transient overvoltage and lightning strikes, and the 2027-09 BLF application is a perfect example of this.
