Gas Discharge Tube Arresters (GDT) are used to protect electrical circuits against high voltage transients by passing the surge current to the ground safely. They are designed to enable a low-impedance path to ground, allowing high-energy transients to quickly divert away from the equipment. GDTs are typically used in power transmission lines, telecommunication networks, broadcast transmission lines, and medical equipment for electrical protection. Gas Discharge Tube Arresters (GDT), such as the PMT3(310)35004 model, have a simple construction. This model consists of two electrodes, one at the centre and one placed inside a metallic housing. The electrodes are separated by an insulating material such as mica. The gap between the two electrodes is filled with a gas, typically nitrogen or sulfur hexafluoride. When there is an increase in voltage to the GDT, the electrodes become negatively charged. The electric field created by the negatively charged electrodes ionizes the gas, forming a channel through which electric current will flow. This forms a path to ground for the energy, protecting the system from damage.The PMT3(310)35004 GDT is designed for overvoltage protection of a variety of circuits, such as power distribution networks, telecommunications, and broadcast transmission lines where lightning protection is required. The GDT has a maximum discharge current of 5 kA and a maximum surge protection of 3 kV. The unit is also designed to be resistant to weathering, vibration, and other environmental factors.Gas Discharge Tube Arresters (GDT) are a reliable and cost-effective method of providing surge protection to circuits. They provide higher levels of protection than traditional surge protection devices, allowing for greater safety and reliability. GDTs can be used for a variety of applications, including power distribution, telecommunications, and broadcast transmission lines, as well as medical equipment. The PMT3(310)35004 GDT is designed for superior protection and reliability, with a maximum discharge current of 5 kA and surge protection of up to 3 kV.
