Gas Discharge Tube (GDT) arresters are devices that protect electronic devices from electrical surges and other system anomalies. These devices can be used in power distribution systems, as well as in telecom and commercial applications. BSPS2255TT is a type of GDT arrester that is suitable for use in telecom and commercial applications. This article will discuss the application field of BSPS2255TT and its working principle.

Application Field of BSPS2255TT

The main application field of BSPS2255TT GDT arresters is in the telecom and commercial industry. This type of arrester can be used to provide protection against transient overvoltages on communication lines in telecommunication systems, such as in telephone exchanges, large LANs and WANs, and data and video transmission systems. It can also be used to protect electrical equipment from voltage transients on AC and DC power lines. In commercial applications, BSPS2255TT GDT arresters are used for protecting electronic devices from power surges caused by lightning or other external source of electrical disturbance.

Working Principle of BSPS2255TT

The working principle of BSPS2255TT GDT arresters is based on the principle of Gas Discharge Tube (GDT). The device consists of a sealed glass tube filled with an inert gas, such as argon. When a transient overvoltage or surge is applied, the voltage across the GDT causes an electrical breakdown of the gas inside the tube, resulting in an intense arc (steep change in current) across the gap. This arc dissipates the large surge energy and protects the device.

In addition to dissipating surge energy, BSPS2255TT GDT arresters also act as voltage-dependent resistors (VDRs). They resist currents above a certain voltage, preventing the device from being damaged due to high currents. The VDRs also serve to limit the overvoltage, allowing normal operation of the system even after a transient overvoltage.

Conclusion

BSPS2255TT GDT arresters are used in telecom and commercial applications to protect electrical equipment from transient overvoltages. They work by creating an intense arc across a sealed glass tube filled with an inert gas when the voltage rises above a certain level. This arc dissipates the surge energy and limits the overvoltage, protecting the device from damage. The voltage-dependent resistors (VDRs) incorporated into BSPS2255TT arresters provide additional protection from high currents.
