Gas Discharge Tube (GDT) Arresters are overvoltage protection devices which use the principle of optical discharge to arrest overvoltages.

GDT Arresters are used to protect electrical circuits, equipment and facilities from damage due to lightning and other electrical disturbances. GDT Arresters are usually mounted at ground level, or at the point of entrance to a building or facility. The GDT Arresters provide protection against voltage spikes and overvoltage surges by using a series of gas discharge tubes which operate in the event that a voltage threshold is exceeded. The tubes are connected in series and are designed to fail open when a pre-set voltage level is exceeded, providing a short-term “break” in the electrical circuit, thereby preventing an overvoltage surge from entering the protected area(s).

GDT Arresters can also be used to protect against power frequency disturbances. These disturbances can be caused by a variety of factors such as a faulty appliance, electrical equipment, or a lightning strike. GDT Arresters are designed to provide protection against power frequency disturbances up to several hundred Hertz. The GDT Arresters use a series of capacitors and inductors to provide a low-impedance path for the disturbance current, thus reducing the effects on the protected area, and preventing the disturbance current from entering the building.

GDT Arresters can be used in a variety of applications. These include industrial, commercial and residential applications, and can be used to protect sensitive electronics, motors, and other equipment from damage in the event of an electrical surge or lightning strike. In addition, GDT Arresters can be used in communication systems, which require protection against lightning strikes and other high voltage disturbances. GDT Arresters can also be used in conjunction with other surge protection devices such as MOVs, varistors, and fiber-optic cables.

GDT Arresters are designed to provide reliable, long-term protection against overvoltage surges and power frequency disturbances. The GDT Arresters are designed to provide a high level of protection and to operate in a variety of environments and conditions. In order to ensure a long life, the GDT Arresters should be tested on a regular basis and should be inspected for possible damage or other concerns. GDT Arresters should also be maintained by trained personnel to ensure their optimal performance.

GDT Arresters are highly reliable devices which provide effective protection against overvoltages and other power frequency disturbances. They are used in many applications and provide a cost effective solution for protecting sensitive equipment from damage due to lightning strikes and other electrical disturbances. GDT Arresters are easy to install and will provide your building or facility with reliable, long-term protection.
