SA2-3000-CLT-STD Circuit Protection

Gas discharge tube (GDT) arresters are designed to limit transient overvoltages and protect electrical and electronic components from potentially damaging effects such as breakdown or discharging. The most commonly used GDT arresters are SA2-3000-CLT-STD, which are designed for medium to high voltage applications. These arresters operate by allowing lightning or other overvoltages to \'bleed\' through, or be discharged, from the GDT whilst protecting the components inside the equipment. In this way, GDT arresters are an ideal solution to protect devices from the effects of lightning strikes when installed in lightning prone areas.

SA2-3000-CLT-STD Gas Discharge Tube (GDT) arrester is a low capacitance arrester specifically designed for medium/high voltage applications for medium frequency work. To work in these applications, the GDT arrester needs to provide a high level of protection whilst allowing a low charge transfer. The SA2-3000-CLT-STD GDT arrester is able to achieve a charge transfer of less than 0.1 picofarads, making them suitable for applications in the 30kV to 95kV range. The SA2-3000-CLT-STD GDT arrester is a robust design that can withstand multiple entries of pulses and is suitable for indoor or outdoor applications in lightning prone areas.

The working principle of SA2-3000-CLT-STD GDT arresters is based on a gas filled spark gap. The GDT contains two electrodes constructed from pressed or sintered alloys. When a surge exceeds the discharge level of the GDT, the resulting spark gap will ionize the gas and create a conducting path. This allows the current to travel safely through the GDT, and away from the components attached to it, thus protecting them from overvoltage damage. Once the surge passes, the arc extinguishes in a fraction of a second, allowing the GDT to reset ready for the next surge.

The SA2-3000-CLT-STD GDT arrester is designed for use in a variety of different application fields, such as industrial or commercial buildings, telecommunications towers, railway signaling systems, transmission and distribution systems, and power utilities. These arresters can be installed easily onto a variety of mounting points, including a pole, wall, overhead line , or as a component of a system like a transformer. Due to their low capacitance characteristics, SA2-3000-CLT-STD GDT arresters are also suitable for medium frequency applications in which the GDT is required to operate at a relatively high frequency..

In conclusion, the SA2-3000-CLT-STD Gas Discharge Tube (GDT) arrester is a reliable and robust solution for medium/high voltage applications in medium frequency fields. Its ability to provide an optimum level of protection whilst maintaining a low charge transfer rate makes it an ideal arrester for lightning prone areas. The SA2-3000-CLT-STD GDT arrester is designed for use in a wide variety of applications, from commercial and industrial buildings to transmission and distribution systems, making it a suitable solution for any situation.
