Gas Discharge Tube Arresters (GDT)

Gas discharge tube (GDT) arresters are specialized surge arresters developed to protect electrical systems and equipment from high voltage transients. GDT arresters are composed of a series of gas-filled tubes that are electrically connected in series. A key feature of the GDT arrester is that it does not need a continuous current to be able to operate. This makes it a more efficient option than some other types of arresters.

The GDT arrester’s design makes it ideal for applications in unpredictable, high-voltage environments where a more traditional surge protector, such as a metal oxide varistor (MOV) or a transient voltage suppressor (TVS), might not work as well. Additionally, GDT arresters do not require external current and are free from degrading over time due to the lack of current.

GTCA28-312L-P03 Application Field and Working Principle

The GTCA28-312L-P03 GDT arrester is specifically designed for outdoor use in industrial, commercial, and utility-grade applications. The device is ideal for applications that require protection from high-energy transients of single or multiple lightning strikes.

The working principle of a GDT arrester is straightforward. When a transient voltage surge or overvoltage occurs, the gas in the tubes is ionized by the electricity, and the electrons are transferred to an ionized path, allowing the surge to be diverted to the ground. This is possible because of the special combination of electrode materials, dielectric, and gas used within the arrester.

The GTCA28-312L-P03 GDT arrester is designed to withstand higher surge currents than traditional surge protectors. It has a maximum continuous operating voltage (MCOV) of 162kV, a 50/60Hz lightning impulse withstand voltage of 128.7kV, and a closing voltage of 110V. It also has a maximum discharge current capacity of up to 156kA.

The GTCA28-312L-P03 also features several design elements that further improve its performance. These include a unique gas-filled tubes design, an optimized electrode material, and an optimized discharge chamber. Additionally, the arrester is designed to keep its mechanical and electrical performance from degrading over time.

The GTCA28-312L-P03 GDT arrester is a robust, reliable solution for applications requiring protection from high-level surge transients. With its combination of high electrical and mechanical performance, the GTCA28-312L-P03 is an ideal solution for protecting electronic systems and equipment from high-level voltage transients.
