Gas Discharge Tube Arresters (GDT)

GTCA25-900M-R02 application field and working principle

Gas Discharge Tube Arresters (GDT) are surge protection devices which protect electronics from over-voltage transients caused by lightning and other electrical disturbances. GTCA25-900M-R02 is a surge suppressor specially designed for protection against both direct lightning strikes and induction coupling. This arrestor is designed with two components, the GCT-900M voltage-limiting component and the RT series spark gap component.

In operation the surge current (caused by a surge such as a lightning strike) passes through the GDT. The GCT-900M voltage-limiting component limits the voltage across the GDT to a safe value. Once the voltage reaches a predetermined level, the RT series spark gap component will fire, and combustible gas is released. This gas will then create a spark and the entire spark arrestor will be extinguished, preventing further damage to the system.

Application Field

The GTCA25-900M-R02 is suitable for a wide range of applications. It is ideal for use in places where high voltage surges and electrical noise are present. Common places include industrial, commercial and residential buildings, shielded LAN cables, electric power devices, computer systems, appliances, and home theater systems. This surge suppressor is also suitable for use in applications where there is a combination of direct lightning strikes and induction coupling.

The GTCA25-900M-R02 is designed to provide the highest level of surge protection against direct lightning strikes and can be used in combination with other surge protection devices to provide an integrated system. This type of arrester also provides excellent protection against ESD or EMI related disturbances.

Working Principle

The GTCA25-900M-R02 works in two stages. In the first stage, the GCT-900M voltage-limiting component limits the voltage across the GDT to a safe value. At the same time, the spark gap component of the arrestor will fire when the voltage reaches a predetermined level. This operation results in the production of a combustible gas which extinguishes the spark. This gas will extinguish the arrester and prevent any further damage to the system.

In the second stage, the device will reset once the voltage is back to a safe level. This resetting process is done automatically and the surge suppressor will be ready to protect against another surge. The GTCA25-900M-R02 is designed to provide maximum protection against direct lightning strikes and can be used in combination with other surge protection devices to create an integrated protection system.

Conclusion

The GTCA25-900M-R02 is a surge suppressor specially designed for protection against direct lightning strikes and induction coupling. The device works in two stages to protect the system against surges, and its resetting process ensures that it is ready to protect against future surges. This surge suppressor is ideal for use in places where high voltage surges and electrical noise are present, and is suitable for use in industrial, commercial and residential buildings, shielded LAN cables, electric power devices, computer systems, appliances, and home theater systems.
