Gas Discharge Tube Arresters (GDT) are surge protection products that are mainly used to protect transmission systems, telecommunication systems, power and instrumentation systems. The SL1002A260SM is one type of GDT with specific applications and working principles. In this article, both the applications and working principles of SL1002A260SM are described in detail.

The SL1002A260SM GDT is suitable for an operating voltage up to 26 kV. It is used for protection against lightning surge voltages at locations in medium voltage systems. One distinctive feature of the SL1002A260SM GDT is that it is zener supported, often referred to as “zebra strip” type for lower voltage GDT. This type of GDT is composed of a pair of parallel zener diodes connected in series. With such a configuration, the SL1002A260SM GDT can limit surge current to both the negative and positive polarities of the arrester. This makes it ideal for use in high voltage systems.

The working principle of the SL1002A260SM GDT can be best explained with the help of an equivalent circuit illustration. In this circuit, the zener diodes serve the role of current shunts. Thus, when a surge voltage is applied, the high voltage current will be shunted off through the zener diodes, thereby preventing the surge voltage from reaching the protected equipment. The SL1002A260SM GDT also features a semiconductor switch that triggers the current shunts in the presence of the surge voltage, so that the surge current can be quickly diverted away from the equipment.

The SL1002A260SM GDT can also provide immunity from electric field stresses. When the going electric field reaches the breakdown voltage of the device, the entire SL1002A260SM GDT breaks down and discharged the electric field. This helps to protect equipment from electric field damage as well. Therefore, these GDTs are suitable for locations that are exposed to lightning strikes, such as those at the top of tall towers or in coastal areas.

The SL1002A260SM GDT offers various benefits including fast response, high current capacities, low operating voltage and good protection against high voltage discharges. This makes it ideal for various applications such as those in outdoor communication systems, telecommunication stations, and others where protection from lightning strikes is needed. Also, the SL1002A260SM GDT is designed to be easy to install and maintain.

In conclusion, the SL1002A260SM GDT is a gas discharge tube with a variety of applications including protection from lightning strikes, electric field stresses, and surge voltages. This GDT features a special zener-supported design and operates on a low operating voltage. It is also easy to install and maintain, which makes it suitable for many locations. With these benefits, the SL1002A260SM GDT can be a valuable asset on any transmission system or telecommunication system.
