Gas Discharge Tube Arresters (GDT): 2039-110-B5LF application field and working principle

Gas Discharge Tube (GDT) arresters are electrostatic devices used to protect electrical equipment from power surges. These devices use a gas-filled tube to act as an electrical "circuit breaker," allowing electrical current to flow through it when the voltage is within safe levels and disconnecting it when the voltage reaches unsafe levels. GDT arresters are designed to protect circuit components from damage due to high-energy transient voltages, such as lightning or overvoltage due to switching operations.

GDT Arresters are widely used in a variety of applications ranging from telecommunications to industrial process control. Some of the most common applications include:

• Power Line Protection
• Industrial Control Systems Protection
• Telecommunications Line Protection
• Surge Protection for Computer Networks
• Lightning Protection Systems

The 2039-110-B5LF GDT arrester is an encapsulated, dual stage transient voltage surge suppressor, designed for a wide range of operating environmental conditions. It is designed to operate effectively at AC rated voltages of 200 to 320V and at a frequency range of 50 to 60Hz. The primary stage of the 2039-110-B5LF incorporates a gas-filled spark gap. This spark gap provides a low impedance path when the surge energy exceeds the spark gap tolerance. The secondary stage utilizes two MOVs in series. The MOVs provide protection for long duration surges and spikes.

The primary and secondary stages of the 2039-110-B5LF protect against overvoltages and line disturbances such as lightning-induced transients, switchgear operations, line-to-line overvoltages, line-to-ground overvoltages and long duration surges. Its internal structure is designed so that the voltage clamping occurs simultaneously in both the primary and secondary stages. This ensures that the device responds quickly to transient voltages, preventing damage to the protected equipment.

In conclusion, the 2039-110-B5LF GDT arrester is designed to provide protection from overvoltages and to disconnect the power line when the voltage reaches dangerous levels. The primary stage of the arrester utilizes a spark gap to provide a low-impedance path, while the secondary stage utilizes two MOVs in series to provide protection against long duration surges and spikes. This device is suitable for a variety of applications, including power line protection, industrial control systems protection, telecommunications line protection, surge protection, and lightning protection systems.
