Gas Discharge Tube Arresters (GDT), or Gas Tube Protectors, are solid-state devices used in electronic circuits to protect equipment against transient/high voltages and surges. The GTCA28-402M-R03 is a GDT designed for applications requiring the combination of high-power handling, high-reliability, and high surge capability. In this article, the application field and working principle of the GTCA28-402M-R03 will be discussed. The GTCA28-402M-R03 is a Gas Tube Protector with a nominal breakdown voltage of 402VDC and a maximum surge handling capability of 4000Amps (8x20µs waveform). It is suitable for use in applications such as power supply lines, solar systems, telecommunication circuits, electric wiring systems, and cable networks. The GTCA28-402M-R03 is designed to protect against high ambient temperatures and the ingress of dust, moisture, and corrosive gases.The working principle of the GTCA28-402M-R03 is similar to that of traditional high-voltage arresters. The device consists of two main components: a ceramic housing that contains a gas or vacuum and a metallic conductor. The metallic conductor has a central terminal that is insulated from the housing. When a potential is applied to the device, the gas in the ceramic housing ionizes and forms a conductive path between the central terminal and the housing, allowing current to flow. When a surge or transient is applied to the GTCA28-402M-R03, the device immediately begins to break down. This breakdown process occurs in two stages: an ionization stage and an absorption stage. During the ionization stage, a high voltage is applied to the device. As the voltage increases, electrons begin to rapidly collide with the gas molecules in the device, producing a chain reaction of ionization. This process continues until the voltage overcomes the ionization potential of the gas. Once the voltage reaches the ionization potential, an electric arc is created, allowing current to flow from the central terminal to the housing. This current is then absorbed into the protective ground system, thus preventing further damage to the equipment. After the current has been dissipated, the electric arc is extinguished and the device returns to its normal state.In conclusion, the GTCA28-402M-R03 is a Gas Tube Protector designed for applications requiring high-power handling, high-reliability, and high surge capability. The device is suitable for use in power supply lines, solar systems, telecommunication circuits, electric wiring systems, and cable networks. Additionally, the working principle of the GTCA28-402M-R03 is based on the two-stage breakdown process, where ionization and absorption are used to dissipate the surge current away from the equipment.
