Gas Discharge Tube Arresters (GDTs) are devices used to protect electrical components and systems from alternating current (AC) voltages. They are commonly used in power plants, substations, telecommunication equipment, and other high-voltage, high-current applications. GDTs are designed to divert surge current beyond a predetermined breakdown voltage into a gas filled tube, and then leak away to the ground.

XT350A-B application fields and working principles are a type of GDT which is used in high-voltage power systems. They are designed to divert high levels of current away from electrical components and systems to ground, in order to prevent injury or destruction to the components. The XT350A-B is composed of a spark gap, an insulator, a gas-filled tube, and a metalised layer. The spark gap acts as the point of breakdown when the voltage surpasses the minimum breakdown voltage of the gap. This causes electron emission, which forms an arc between the electrode points of the gap. The insulator around the spark gap keeps the arc from coming in contact with other parts of the device.

The arc from the spark gap then passes through the gas-filled tube to the metalised layer which wraps around the exterior of the tube and forms the primary point of grounding. The arc is dissipated into the ground, away from the electrical components and systems, and the device is then able to reset itself after the arc is dissipated. The XT350A-B devices can be used in both AC and DC electrical systems, and can be used to protect components from surges ranging from 1kV to 66kV.

In conclusion, XT350A-B application fields and working principles are an important component in the world of electrical safety. They are used to protect electrical components and systems from AC and DC voltages, and can be used in a variety of applications. They are composed of spark gap, insulator, gas-filled tube, and metalised layer, and provide protection from surges ranging from 1kV to 66kV. By using the XT 350A-B, businesses can ensure the safety of their electrical systems and components.
