Gas Discharge Tube Arresters (GDT)

The 2036-23-SM-RP arrester is a Gas Discharge Tube (GDT) arrester. This type of arrester utilizes gas filled tubes filled with noble gases or sulfur hexafluoride gas and can be used to protect a wide variety of transformer or generator components from transient currents and lightning strikes.

Application Field

GDT arresters are commonly used in distribution, substation and power factor correction equipment such as transformers, generators and voltage regulators. They are also capable of providing surge protection to a wide variety of over-voltage protection applications, including electronic instrumentation, communication cables, navigation buoys and aircraft avionics and power systems.

Working Principle

The GDT arrester works on the principle of spark gap conduction. The gas filled tube, filled with either noble gas or sulfur hexafluoride, is the spark gap. When current rises above a certain threshold level, the spark gap conducts, thus carrying the current and preventing damage to the protected equipment or system.

The spark gap is designed to allow current pulses above a certain threshold to occur without causing damage to the arrester. The spark gap contains an electrically charged material. When a surge or voltage that is higher than the breakdown voltage of the material occurs, current is conducted through the spark gap, allowing the pulse to pass through without significantly damaging the arrester.

Conclusion

GDT arresters, such as the 2036-23-SM-RP, are designed to provide surge protection to a wide variety of applications. The spark gap in the GDT arrester allows current pulses above a certain threshold to pass without damaging the arrester and the protected components.
