Gas Discharge Tube arresters, or GDTs, are devices that are used to protect electro-mechanical and electronic systems from lightning-induced surges and related high-voltage transients. While these devices are designed to have a wide range of settings for handling the varying scenarios that might arise, they all share a common design and operating principle. In this article, we will be discussing the application field and working principles of the 2035-42-B model GDT.

Application Field of the 2035-42-B Model GDT

The 2035-42-B is designed to protect sensitive electronic and electro-mechanical systems against high voltage transients, as a result of nearby lightning strikes or other means. It is typically used in distribution networks, particularly telecommunications, where high-energy currents can be expected due to lightning strikes or other sources. It is also suitable for protecting systems from over-voltages, such as those caused by switching surges.

The device is designed to have a wide operating voltage range, from 7V to 13kV. It is rated for high-voltage operations up to 35kV, and is resistant to thermal and shock stress. As with other GDTs, it also protects against large transients, such as those caused by the power line hitting an object.

Working Principle of the 2035-42-B Model GDT

All GDTs share a similar design and operating principle. The 2035-42-B model is no exception. The device has an outer shell that surrounds a gas-filled tube. This tube contains both a protective coating and a triggering device, typically a varistor or metal oxide varistor (MOV).

When a high voltage transient occurs, the fast-acting triggering device will short the tube. This creates a path for the electrical current to flow, which has the effect of dissipating the high voltage and preventing it from entering the protected system. This process is known as current limiting, and is what distinguishes GDTs from other protective devices.

After the transient has passed, the GDT will reset itself and be ready to protect again. This is due to the design of the tube, which enables it to quickly cool down and reset. In addition, some GDTs, including the 2035-42-B, also feature a moisture displacement system, which helps protect against excess moisture in damp, humid areas.

Conclusion

Gas Discharge Tube Arresters (GDTs) have become increasingly popular as a means of protecting sensitive electronic and electro-mechanical systems from lightning-induced surges and related high-voltage transients. This article has provided an overview of the application field and working principles of the 2035-42-B model GDT, which is designed to provide a wide operating voltage range and strong protection against large transients.
