Gas Discharge Tube Arresters (GDT),are components used in the distribution and transmission line systems. They help to protect electrical equipment from lightning strikes and other electrical lightning disturbances by limiting the voltage spikes. As the technology continues to develop, the applications and working principles of GDT become more and more complex. The most advanced GDT device today is the 2028-25-CLF.

Introduction To 2028-25-CLF

The 2028-25-CLF is a type of GDT with 25 kV surge rating and meets the UL 1449 standard for high-voltage arresters. It features a fast-acting Silicon Carbide (SiC) protective layer that can be used in lightning surge protection, current limiting, and frequency-response functions. This advanced GDT device is designed to handle a maximum peak current up to 4.5 kA, and a pulse repetition rate of up to 8 kHz. It has a natural frequency response of 50 Hz to 500 kHz and a surge current of 5 kA.

Applications

The 2028-25-CLF has a wide range of applications. It can be used in a variety of distribution and transmission line systems, including utilities, industrial, commercial, and residential. It is suitable for protecting against lightning strikes, as well as surges from non-lightning events. It is also an ideal device for monitoring current, limiting peak and repetitive currents, providing an impedance, and for frequency-dependent attenuation of harmful transient impulses.

In addition to protecting electrical equipment from lightning strikes, the 2028-25-CLF is suitable for applications such as over-voltage protection, low-impedance protection, and short-circuit protection. It can also be used in sensitive electrical commercial lighting systems, telecom systems, and data networks.

Working Principle

The 2028-25-CLF works by using an integrated SiC-based diodes protected by metal-oxide gas tubes. When a surge or transient occurs, the gas tube breaks down and a spark gap is formed. This spark gap limits the voltage that can pass through the device, thus protecting the attached equipment.

When the transient voltage spike is at its highest point, the spark gap can reach temperatures as high as 10,000 Kelvin. The SiC diodes simultaneously respond by applying a reverse voltage, creating a blocking effect which reduces the incoming voltage. This will then be followed by an inverse current that will gradually decrease, until the voltage reaches zero again. This ensures that the circuits of the attached equipment are not damaged by the surge or transient.

Conclusion

The 2028-25-CLF is the latest development in Gas Discharge Tube Arresters technology. The device is designed to offer superior performance and protection against prolonged surge activity and voltage spikes, and is suitable for a variety of distribution and transmission line applications. It works by employing an enclosed SiC based diode protection and a metal-oxide gas tube that limits voltage when there is a surge or transient. It is capable of responding and attenuating high-voltage transients quickly and efficiently, thus helping to protect attached electrical equipment from damage.
