Gas Discharge Tube Arresters (GDT) are devices that are used to protect electrical equipment from the effects of high energy surges. They are used to prevent damage from lightning and other electrical disturbances such as lightning-induced transients and high-voltage switching. GDTs utilize the natural resistance of gases in their construction, which allows them to provide a low impedance path from the source of the surge to the ground, allowing the energy to be directed away from the sensitive components of the electrical equipment.

The 2038-80-SM is a special type of GDT that utilizes an advanced gas combination to provide maximum protection while being one of the smallest arresters available on the market. The 2038-80-SM is a spark gap arrestor which is designed for use on high voltage circuits. This type of arrester differs from other spark gap arresters in that it does not require an internal ground connection. Instead, it utilizes an output line resistor and a corresponding ground connection which is external to the arrestor. This allows for easier installation, and a lower cost of protection without sacrificing protection against high voltage phenomenon.

The 2038-80-SM is designed to operate in two different modes. The first and most common mode is the alternating current (AC) mode. In this mode, the arrester is used to provide the necessary paths for the current to travel to the ground, while limiting the voltage potential and protecting the equipment from surge voltages. The second mode is the direct current (DC) mode. In this mode, the arrester acts as a low impedance connection, redirecting the energy away from the sensitive components of the equipment.

When the 2038-80-SM is in AC mode, the internal gas within the arrester will be activated by the high voltage current. The electrical current will pass through the spark gap portion of the arrester, which will produce a spark to ignite the gas. The gas will then create a lower impedance path, which will stretch the voltage potential and provide a short time arc path to ground. This will limit the surge voltage and provide overall protection to the equipment it is protecting.

When the 2038-80-SM is in DC mode, the gas will behave differently. The arrester will activate a current path, but the gas will be not be ignited and no spark will be produced. The current path will be of lower impedance, which will stretch the voltage potential and again provide protection to the equipment it is protecting, albeit at a slightly lower level than in AC mode. This is because the current can flow through the resistor and still provide the protection needed.

Overall, the 2038-80-SM gas discharge tube arrester provides reliable and effective protection from high voltage surges and is one of the smallest and most cost effective GDTs on the market. It is designed to provide protection in both AC and DC modes, and is therefore well suited for use in high voltage applications.
