2097-120-DLF

Gas Discharge Tube Arresters (GDT) are specialized devices used in power systems to protect electrical equipment from transient overvoltage spikes caused by lightning strikes or system faults on high-voltage lines. The 2097-120-DLF GDT arrester is designed to protect power systems from such damaging overvoltages. This article will discuss the application field and working principle of this arrester.

Application Field:

The 2097-120-DLF GDT arrester is designed to protect power systems from all types of transient overvoltages. It can be used in high-voltage distribution systems, such as 3-phase and single-phase lines, as well as in applications such as substations, telecommunications, power substations, nuclear plants, and lightning. The arrester is designed to protect against overvoltages ranging from 1.2 kV up to the maximum working voltage of its end-use system.

Working Principle:

The 2097-120-DLF GDT arrester functions like a valve. It contains a gas-filled element such as oxygen, nitrogen, or a mixture of gases. This gas has a low dielectric strength, which means that it can break down under excessive voltages. When an overvoltage occurs, the gas-filled element is subjected to an ionization process which causes it to create a conductive path that channels the overvoltage away from the power system and dissipates it.

The arrester works on a reactive principle, meaning that it is able to respond quickly to changing electric fields and currents, allowing it to protect power systems from fast-rising transient overvoltages. The 2097-120-DLF arrester also utilizes a metal oxide varistor (MOV) element which is designed to absorb voltage peaks and reduce overvoltages.

The 2097-120-DLF GDT arrester is designed with a number of features that provide enhanced protection for power systems. These features include surge protection from lightning, protection from ground-fault currents, and transient harmonic wave protection from power surges. Additionally, the arrester features a built-in indicator light that displays the status of the arrester, allowing for easy monitoring of its functioning.

In summary, the 2097-120-DLF GDT arrester is designed to protect power systems from transient overvoltages. It utilizes a gas-filled element that is subjected to an ionization process, which allows it to create a conductive path for the overvoltage. The arrester also features an MOV element designed to absorb voltage peaks and reduce overvoltages. Additionally, the 2097-120-DLF GDT arrester features a number of features that provide enhanced protection for power systems, including surge protection from lightning, protection from ground-fault currents, and transient harmonic wave protection from power surges. With its ability to provide reliable protection from overvoltages, the 2097-120-DLF GDT arrester is an invaluable asset to any power system.
