Gas Discharge Tube Arresters (GDT) are used in a variety of applications, such as telecommunications, networking, power distribution, and lightning protection. GDTs are designed to protect sensitive devices and power lines from transient overvoltage by providing a controlled path to ground when the voltage exceeds a certain level. The GTCA25-401M-R02 is an exemplary Gas Discharge Tube Arrester (GDT). Here, we will discuss its application field and working principle.

The GTCA25-401M-R02 is designed to protect against overvoltage and transient pulses on up to 100 kV systems. This surge protector has two separate gas discharge tubes, which provide reliable protection for different types of overvoltages, such as those induced by lightning and other sources. With its superior high-current performance, the GTCA25-401M-R02 is suitable for use in telecommunications systems, as well as in powerlines, computer systems, and other electrical appliances. Its dual tube design makes it highly effective in preventing damage from transients.

The working principle of the GTCA25-401M-R02 is based on Gas Discharge Tube (GDT) technology. The arrester comprises of two tubes, each filled with a noble gas mixture. When a high voltage surge or transient is generated, the gas molecules become ionised, creating a conducting path between the two tubes. This allows the current to pass from one tube to the other, dissipating the surge and protecting the connected equipment from damage.

The GTCA25-401M-R02 also has a built-in safety feature to protect against catastrophic arcing. This ensures that the GDT is not damaged if an overload is applied. The arrester also has a temperature correction circuit which ensures its performance over a wide temperature range, from -50°C to +70°C. Additionally, it has a reviver warning light that indicates when the arrester needs to be replaced.

In summary, the GTCA25-401M-R02 Gas Discharge Tube Arrester is designed to protect up to 100 kV systems from damaging transients. It uses GDT technology to provide a conducting path for the surge current, and a built-in safety feature prevents catastrophic arcing. The arrester also comes with a temperature correction circuit and a warning light, ensuring that it works reliably over wide temperature ranges.
