Gas Discharge Tube Arresters (GDT) are an integral component of power systems for protection against lightning induced transients. Used in combination with other components like surge suppressors or surge diverters, GDT is an important element in lightning protection assemblies. GDTs are designed to protect electrical and electronic equipment from transient overvoltages caused by lightning strokes.

A GDT is a specialized non-linear electronic protection element that works by providing a conductive path for current generated by lightning or surges in power lines. It can be described as a two-terminal, non-linear resistor characterized by a negative resistance characteristic. This negative resistance characteristic works in two ways: first, it causes the GDT to be more conductive at higher voltages; second, it causes the GDT to be more conductive at lower currents.

The 2003-25-SM-RPLF GDT works by providing low-impedance, high-resistance paths for current generated by lightning. This low-impedance path provides protection against overvoltage transients caused by lightning strikes. At the same time, the high-resistance path limits current surge levels to keep transients from damaging protected equipment during a lightning strike. As a result, the 2003-25-SM-RPLF GDT has high performance for use in lightning protection assemblies.

In addition to its application in lightning protection, the 2003-25-SM-RPLF GDT has other important uses. It is used in many industries for surge protection, such as medical equipment, IT and telecoms, industrial automation, home appliances, and so on. The GDT is also used in power electronics and in high-frequency radiating devices, as its low-impedance, high-resistance characteristics can help reduce interference or crosstalk from other sources. The 2003-25-SM-RPLF GDT can also be used in printed circuit boards to limit the current flowing through components.

The 2003-25-SM-RPLF GDT has a working principle based on metal-oxide varistors (MOVs). The varistor element of the GDT is composed of zinc oxide pellets or strips, which are surrounded by a metallic case and wrapped in an insulating material. The settling time of the varistor is based on the type and size of pellets or strips used. When exposed to a voltage over a certain threshold value, the MOVs operate in an non-linear manner, becoming more conducting and allowing current to flow. This allows the GDT to provide protection against overvoltage transients.

The 2003-25-SM-RPLF GDT also provides protection against multiple lightning strikes in an area. A majority of GDTs also have multiple leads, enabling them to be connected in parallel. This arrangement allows them to have a very low impedance and to share the current load between them, ensuring a greater level of safety. Furthermore, GDTs are also designed to self-regulate their current and noise levels, making them suitable for use in sensitive equipment.

The 2003-25-SM-RPLF GDT offers a number of advantages for use in lightning protection assemblies. Its low impedance, high-resistance characteristic is suitable for use in sensitive equipment. Additionally, it provides high performance even under multiple lightning strikes, and its self-regulation ensures reliable protection. Finally, GDTs are highly reliable components, with a long service life and low maintenance requirements.
