Gas Discharge Tube Arresters (GDT) is a specialized device that is most commonly used for protection against electrical surges. GDTs are of two types; a surge arrestor and a lightning arrester. A surge arrestor is used to protect against transient overloads or overvoltages, while lightning protection is used against direct lightning strikes.

The 2027-09-B GDT is a device used for protection against both overvoltages and more intense and damaging lightning strikes. It has two sections, a primary and secondary. The primary section consists of a gas-filled sealed glass tube with an electrically conductive region between the anode and the cathode. Depending on the type of GDT, the electrically conductive region is either filled with a noble gas or is dry and typically consists of an alloy of zinc and magnesium or other conducting material.

When an electric potential is applied to the anode and cathode of the GDT, the gas within the sealed glass tube will be ionized. The ionized gas forms an arc between the anode and cathode and current will flow to the other side of the device. It is the arc which is responsible for the protection that is provided by the GDT.

The Secondary section of the GDT is made up of an inductor which is designed to limit the current that is conducted across the device and protect it from damage. As the arc is formed, current will flow from the anode to the cathode of the GDT and the inductor will attenuate the current spike when the arc dissipates. Without the inductor, the current spike could damage the GDT and become a source of additional surges.

Once the current has been attenuated by the inductor, the secondary component of the GDT will also conduct a reverse voltage to the power source, limiting the potential effect of the surge and helping to protect equipment and devices to which the power source is connected.

The 2027-09-B GDT is designed to provide protection against voltage spikes, transient overvoltages, and lightning. It can be used in a variety of applications, including communication and power systems, automobile electronics, and home appliances. The device will provide protection against lightning events, as well as limiting the effects of both short and long-duration voltage transients.

In summary, the 2027-09-B GDT is a specialized device that is used to protect electrical systems and equipment from transient overvoltages and lightning strikes. It is typically composed of two parts, a primary section made up of a sealed glass tube containing an electrically conductive region, and a secondary section made up of an inductor that helps limit current spikes caused by the arc that forms between the anode and cathode of the GDT.
