Gas Discharge Tube Arresters (GDT) has been widely used in electrical protection systems for quite a long time. It is composed of various parts such as gas tube, arrester grid, movable contact, dummy contact points, pressure regulating diaphragm, etc. SL1024B400RG is one of the leading GDT arresters with advanced design. In this article, we will discuss about the application field and working principle of SL1024B400RG.

Application Field

SL1024B400RG GDT arrester can be used in the protection of high voltage circuits and substations, in order to protect the device from overvoltage surges or short circuits. It is also ideal for use in power plants, telecom base stations, transmission lines and other high voltage power systems. Moreover, this device can be used as a surge suppressor or overvoltage protector in outdoor equipment, such as high altitude towers, telecom and power lines.

Working Principle

SL1024B400RG GDT consists of two basic parts. The first part consists of a gas-filled tube, which acts as the main part of the arrester. Inside the tube is a combination of different gases, such as nitrogen, hydrogen, and a noble gas. The gas molecules in the tube are highly conductive, and the gases, due to their ionization, can absorb a lot of voltage energy.

The second part is the grid. It has a mesh of conducting wires which surrounds the gas filled tube. These wires act as a shield to prevent any direct ‘short’ in the case of an overvoltage surge. In other words, it serves as an electric ‘fuse’, by quickly discharging the excessive surge voltage to the ground.

In the event of an overvoltage surge, the grid absorbs the extra energy, which is then dissipated by the gas tube. The gas molecules act as a ‘buffer’, and the excess voltage supplied by the surge remains safely conducted away from the system without doing any damage to the circuits or the equipment.

Overall, the SL1024B400RG GDT arrester is an efficient apparatus, which provides protection against a wide range of overvoltage conditions with minimal malfunction. It provides superior insulation performance, is low in cost, and is easy to install and maintain. It is designed for high performance in all types of weather conditions and offers an accurate voltage protection level.
