Gas Discharge Tube Arresters (GDT)

The 2061-35-ALF application field and working principle of Gas Discharge Tube Arresters (GDT) are a form of overvoltage protection devices. They are designed to protect electrical equipment from any potentially hazardous electrical surges and transients. Typically, GDTs are composed of an insulated plastic or glass tube filled with a pressurized gas. Inside the tube, an electrical charging plate is located which is maintained at a lower voltage than the outer electrode. Upon occurrence of an electrical surge, the gas within the tube ionizes and forms a conductive plasma path between the two electrodes, thus allowing the surge to be safely discharged.

The advantage of using a GDT lies in the fact that it can dissipate high surge voltages with much lower let-through currents than any other form of arrester, such as air gaps, spark gaps and various other current-limiting devices. This allows for more efficient protection, which is especially important in applications with medium and high voltage installations, where the protection of expensive equipment becomes critical.

The 2061-35-ALF GDT is designed for use in applications where medium voltage and high voltage power lines are present. It is ideal for use in areas with high lightning activity and strong electrical disturbances. The unit is excellently capable of protecting transmitting antennas, power lines, radio systems, and any other expensive electronic devices against severe damages.

Typically, the 2061-35-ALF GDT consists of two electrodes, one positive and one negative. The positive electrode is held at a greater potential than the negative electrode and thus is also referred to as the \'leader\'. When an overvoltage condition is detected in the system, a spark gap is activated and the voltage in the system is grounded, thus allowing the high voltage to discharge across the spark gap. The GDT\'s spark gap is designed to be extremely sensitive and able to detect even the smallest changes in voltage within a system. Once this trigger is activated, the two electrodes on the GDT create a plasma bridge and, in a matter of microseconds, allow the voltage in the system to be safely and quickly reduced back to a safer level.

Overall, the 2061-35-ALF GDT is an incredibly useful device which offers both immediate and long-term electrical protection, ensuring that your electrical systems can remain operational for years to come. Thanks to its ability to easily detect overvoltage conditions, the GDT provides an excellent level of protection to any system, allowing for complete peace of mind and lower costs associated with electrical system maintenance.
