Gas Discharge Tube Arresters (GDT) is widely used in many electrical systems, providing a high level of protection against any voltage transient. The XT600A-B model of GDT is one of the most popular and reliable, and offers steady and reliable protection against voltage transients. This article will introduce the application field and working principle of XT600A-B.

Application field of XT600A-B

XT600A-B is a type of metal oxide surge arrester with two tubes, suitable for low frequency and low-voltage power distribution system up to 600V. XT600A-B operates in two stages, with a fast response for small energy transients such as lightning strikes, and a slower response for higher energy transient operations. It is often used for lightning protection broadband systems, and for protecting signal and communication systems against voltage transients. It is also ideal for protecting small transformers and induction motors, as it allows for short-term overload current protection.

XT600A-B is designed to operate in a wide range of temperatures, from -40°C to +85°C, and in a wide range of atmospheric conditions, from 0% to 100% humidity. It also offers excellent protection against mechanical impacts, and has an extensive life expectancy provided it is operated in accordance with the manufacturer’s guidelines and rated conditions. Additionally, XT600A-B has an improved sparkover voltage, suitable for both AC and DC applications, and offers a wide range of mounting options, from direct mounting to suspension mounted configurations.

Working Principle of XT600A-B

The XT600A-B gas discharge tube arrester consists of two tubes, each having its own capacitive and resistive elements. The first tube, known as the "parallel circuit" or the "capacitor tube", is composed of two electrodes, which are connected to a protective equipotential bar in series with the ground. The second tube, known as the "auxiliary tube" or the "voltage limiter tube" is composed of two electrodes connected across the output. When a transient voltage spike is applied to the arrestor, the parallel circuit is designed to rapidly discharge any energy stored up in the capacitors, while the auxiliary tube allows for a slower discharge of any transient energy.

The two tubes are connected in series, with the parallel circuit having a much lower capacitance than the auxiliary tube. This results in the parallel circuit having a very fast response and the auxiliary tube having a slower response. When a transient voltage spike reaches the arrestor, the first stage of protection is provided by the parallel circuit. This circuit absorbs energy from the voltage spike and dissipates it quickly, dissipating the spike without it reaching the equipment. The second stage of protection is provided by the auxiliary tube, which will limit the peak voltage and enable the discharge of any energy that has already been left by the parallel circuit.

The XT600A-B metal oxide surge arrester is able to provide protection against discording electrical power surges in environments with very high levels of humidity, temperature range, humidity fluctuations, strong solar radiation, and strong electrical fields. In addition, its two-stage technology aids XT600A-B in providing precise and reliable protection against transients, even in difficult environmental conditions.

Conclusion

XT600A-B is one of the most popular and reliable gas discharge tube arresters, suitable for protecting small transformers, induction motors, signal and communication systems, broadband systems, and other electrical systems. This model of GDT operates in two stages, with a fast response and slower response, and is designed to work in a wide range of operating temperatures and atmospheric conditions, including high humidity and strong solar radiation. Additionally, its two-stage protection scheme helps XT600A-B accurately and reliably protect any electrical system against transient voltage spikes.
