Gas Discharge Tube Arresters (GDT)

Gas discharge tube (GDT) arresters are electrical surge protection devices designed to protect sensitive electrical circuits from the potentially destructive forms of lightning, switching, and environmental disturbances. GDTs are designed to react quickly to high-voltage transients and suppress the energy of the circuit to protect it from various types of damages. The primary advantages of using GDTs are cost-effectiveness, fast response, and reliability in protecting sensitive equipment.

C2LF application field

C2LF Gas Discharge Tube Arresters are designed for use in environments where transient over-voltages may occur. These applications include telecommunications, power transmission and distribution systems, computer networks, and industrial process control systems. C2LF units are designed to limit the voltage in a given circuit to a predefined safe level in the event of a transient surge. This provides protection to the equipment the arrester is connected to, such as computers, actuators, power supplies, and other sensitive electronic equipment. C2LFs are also used to protect power systems from direct lightning damage. The C2LF\'s fast response time helps to protect equipment from lightning surges, which can range from 10 µs to 50 µs.

Working principle of C2LF

The operation of the GDT is based on the principle of gas ionization. During normal operating conditions, there is no current flow through the tube since the voltage across it is lower than its breakdown voltage. However, when a transient voltage occurs, the voltage across the tube exceeds its breakdown voltage, and electrons start to ionize the gas inside the tube. This ionized gas, or plasma, reduces the effective electrical pass of the tube, thus limiting the voltage across the tube and thus protecting the equipment connected to it. The GDT will remain in this state until the over-voltage is removed. Once the over-voltage is removed, the tube can recover to its initial state and is ready to provide protection again when needed.

Advantages of C2LF

The use of GDTs offers a number of advantages over traditional surge protectors. First, GDTs can handle a greater range of surge energy levels while still providing protection. Second, they react more quickly than traditional protectors, allowing them to react faster to a transient surge. Finally, they are more reliable and cost-effective. GDTs are capable of withstanding multiple transient surge events without needing to be replaced, making them a more economical option over the long term.

Conclusion

Gas discharge tube arresters (GDTs) provide reliable, cost-effective protection from transient over-voltages in a wide range of applications. They can handle a higher range of energy levels than traditional surge protectors and react faster to transient surges. They are also highly reliable and capable of withstanding multiple surge events without needing to be replaced. The C2LF is specifically designed to provide superior protection against lightning induced transient over-voltages and thus provide the necessary protection against direct and indirect lightning damage.
