Gas Discharge Tube Arresters (GDT) are used to protect electrical systems from voltage surges caused by lightning or other electrical faults. The 2036-25-B is an example of such a device, designed for medium-voltage applications. This article will explain its field of application and working principle.

Field of application

The 2036-25-B is designed for use in medium-voltage (MV) applications, with a rating of 15 kV to 25 kV. It is suitable for new or existing overhead transmission and distribution lines, as well as for the protection of medium-voltage distribution transformers. As it is designed to work with AC or DC systems, it can be used in a wide range of applications.

Working principle

The 2036-25-B is a Gas Discharge Tube (GDT) based arrester. It works by discharging high voltage surges to ground through a gas-filled cavity. The gas within the cavity is made up of a number of noble gases, which will ionise and form a low-resistance path between the arrster and ground when a high voltage surge is present. This path will quickly dissipate the excess energy from the surge, protecting the device from damage.

The GDT also has an external resistor, which is used to absorb and dissipate any residual energy that is not dissipated by the gas discharge. This helps to reduce the energy of the surge, further protecting the electrical system. The GDT can also be used in conjunction with other surge suppression and protection devices, such as capacitors and arresters, to provide a more comprehensive protection system.
