Gas discharge tube arresters (GDT) are essential components of electrical systems that are designed to protect them from damage due to overvoltages. The 2036-42-C2 application field and working principle are important for understanding how these devices work and how they protect the power systems.

Overview of GDTs

GDTs are devices composed of two electrodes encapsulated in an outer tube that is filled with an insulating gas. There are two main types of GDTs: spark gap type and pressure exhausting type. The construction and working principle of both types are based on a two-stage current interruption process. In the first stage, the overvoltage is transmitted to the arrester and its insulation resistance is broken down. This causes a large current to flow in the GDT. In the second stage, the energy stored in the GDT is transformed into a light and heat discharge which neutralizes the overvoltage.

2036-42-C2 Application Field and Working Principle

The 2036-42-C2 application field includes both indoor and outdoor applications for protection against power system overvoltages. These Arresters are purpose-designed to provide clear and reliable protection against lightning strikes and power surges. The 2036-42-C2 is a pressure exhausting GDT arrester with a strike voltage of 4.25kV. The internal construction and working principle of this arrester involve several components. First, there is an insulating pellet of quartz crystal which serves to break down the insulation resistance of the device when an overvoltage is present. The quartz crystal then allows a small current to flow through the arrester, which is then transformed into a light and heat discharge. This discharge transfers the excess energy safely away from sensitive components of the power system such as, transformers and circuit breakers.

Advantages of GDTs

GDTs are superior to conventional surge arresters in several ways. First, GDTs are lightweight and smaller than conventional arresters which makes them easy to install and maintain. GDTs also have a longer life span as compared to conventional arresters due to their consistent performance over time. Furthermore, GDTs are not prone to aging due to temperature changes, time-dependent accumulations of energy, or corrosion. Finally, GDTs provide superior protection against lightning strikes, power surges, and overvoltages when the appropriate type of device is installed.

Conclusion

In conclusion, Gas Discharge Tube Arresters remain one of the most reliable and essential components of any power system. The 2036-42-C2 GDT device is an important part of the protection system and requires a clear understanding of its application field and working principle in order to provide the necessary protection. GDTs have numerous advantages over conventional arresters, such as their small size and long life span, and offer superior protection against lightning strikes and power surges.
