Gas Discharge Tube Arresters (GDT) are used in a variety of high-voltage applications, from lightning protection to power-factor correction. The 2036-47-B3LF GDT is an example of a GDT specifically designed for lightning protection and lightning discharge applications. This article will provide a brief overview of the 2036-47-B3LF GDT application field and working principle.

The 2036-47-B3LF GDT is designed for energized overhead or underground power distribution system structures and poles. The arrester’s rated voltage is 150kV, the maximum discharge current is 100kA, and the maximum energy dissipation is 1MJ. The GDT is designed to limit the voltage surges created by lightning strikes and other line disturbances, and to protect the connected equipment from electrical disturbances.

GDTs have a working principle that is based on the Townsend avalanche. In a Townsend avalanche, a high-voltage electric field is generated, which causes the electrons in the gas-filled tube to accelerate and collide with the gas atoms or molecules. As a result, the molecules are ionized and a high-current pulse is generated. The pulse current passing through the GDT causes its impedance to rapidly increase, thus limiting the voltage surges in the distribution system.

On the protection capability side, the 2036-47-B3LF GDT offers excellent protection for explosions, lightning strikes, and transient overvoltages. The arrester is also designed with a wide range of lightning protection features, such as an enhanced surge capability, a 10/350 μs pulse shape rating, and ring current protection. It also has a reverse-connection protection feature that can help protect the connected equipment and system from unintended electrical disturbances.

The 2036-47-B3LF GDT is also designed with reliability in mind. It has an IEC 61643-1 Type 3 air-break switch, which is designed to ensure reliable protection in the event of a short circuit. The arrester also has a high-power limiting function, which prevents the breach of system overcurrent limits. In addition, the GDT is resistant to corrosion, making it well suited for use in outdoor applications.

In conclusion, the 2036-47-B3LF GDT is designed to provide reliable and efficient protection for energized overhead or underground power distribution systems. It has a rated voltage of 150kV, a maximum discharge current of 100kA, and a maximum energy dissipation of 1MJ. The GDT offers excellent protection for explosions, lightning strikes, and transient overvoltages, and is designed with a wide range of lightning protection features. Finally, the GDT is designed with a high-power limiting feature for reliable protection in the event of a short-circuit.
