Gas Discharge Tube Arresters (GDT)

SL1003A090RF is a type of Gas Discharge Tube (GDT) arresters. GDT arrester is an external overvoltage protection device used in electrical power s ystems. GDTs provide overvoltage protection by dissipating electrical energy in a controlled manner when hit by a lightning impulse. The SL1003A090RF, with a nonlinear resistive gas medium, is an important component used in the electrical power system for protection against electrical surges and transients.

Application Field

Gas discharge tube arresters are widely used in telecommunications, power grid, and other electrical or electronic equipment. This type of arrester has a wide range of applications, such as radio and television equipment, hardware and software for computer communication, lightning protection systems, bridges, ports and airports, oil and gas pipelines, power station secondary voltage equipment, electric power control systems, medical facilities and more. In addition, they are used in applications such as spacecraft, aviation, military and extreme environment.

Working Principle

When an external overvoltage appears, an arc discharge occurs in the inrush current of the SL1003A090RF, and the spark breakover efficiently interrupts the current due to the improved pressure drop. The working principle of the SL1003A090RF is based on the air gap triggered by an overvoltage voltage. When the applied voltage overcomes the protection voltage provided by the air gap, the arrester is triggered into action and provides a high current path for the discharge. This is because theresistance of the arrester is much lower than that of the air gap. After the overvoltage is removed, the arrester returns to its normal state.

The SL1003A090RF is a gas discharge tube arrester with an operating voltage of 900 volts and a surge arrestor operating voltage of 470-820 volts. It has a high capacitance and a low-resistance self-recovery process. It can ensure that most surge signals above its operating voltage are suppressed, avoiding damage to the target equipment. This type of arrester can be used in low voltage systems, such as single-phase, three-phase and lightning protection systems, and is suitable for applications such as communication networks, power systems and medical equipment.

Conclusion

SL1003A090RF is a type of gas discharge tube arrester, which provides protection against overvoltage for electrical power systems. It is widely used in telecommunications, power grid, and other electrical or electronic equipment. The working principle is based on the air gap triggered by an overvoltage voltage, and it has a high capacitance and a low-resistance self-recovery process. It can ensure that most surge signals above its operating voltage are suppressed, avoiding damage to the target equipment.
