Gas Discharge Tube Arresters (GDT) is a key technology used in electrical power applications, with the aim of protecting energy systems from transient over-voltage. GDTs are a type of surge-arrester which provides a high level of protection against voltage transients and surges. Typically, these devices are connected in-line with the power distribution system and absorb the excess energy generated by a transient. In order to provide effective protection, the GDT must be correctly selected for the required application and its working principle understood. This article will focus on the 2026-25-C4 GDT in particular, and provide an overview of its application field and working principle.

The 2026-25-C4 is a 225V gas discharge tube arrester designed to provide effective protection against transient impulses, lightning strikes, and voltage surges. This GDT has a high power handling capability of up to 100 kA (8/20 μs). It is also highly resistant to mechanical damage, with an IP65 rating and the ability to withstand up to 1.2kV of continuous voltage. Furthermore, its compact design and low leakage current makes it suited to a variety of applications.

The primary application field of the 2026-25-C4 is in outdoor energy distribution applications. It is often used in substations and electrical grids, providing protection against transient impulses which can damage systems and cause outages. It is also suitable for use in telecommunications systems, providing protection against lightning strikes and high-voltage surges.

The working principle of the 2026-25-C4 GDT is based on the phenomenon of electrical breakdown. Under normal operating conditions, the GDT is essentially an open circuit, allowing the power system to function without interruption. When a voltage transient occurs, the electrical field within the GDT is increased. At a critical voltage, electrical breakdown occurs and the arrester conducts the electrical energy away from the system, thus providing the necessary protection.

Furthermore, the GDT operates in a self-resetting manner. After the transient is absorbed, the current is diverted away and the arrester returns to its open-circuit state. This makes the device highly reliable, and ensures proper protection when needed.

In conclusion, the 2026-25-C4 GDT is a device designed to provide effective protection against voltage transients and surges. It is often used in outdoor energy distribution systems, and is suited to telecommunications applications as well. The working principle of the device is based on the phenomenon of electrical breakdown, in which the arrester absorbs and diverts surges away from the power system, protecting it from damage. It operates in a self-resetting manner, ensuring continuous protection against transients.
