Gas Discharge Tube Arresters (GDT)
Gas discharge tubes, abbreviated as GDT Surge Arrestors, function as voltage-base switches. When a voltage is distributed throughout the devices and is greater than its direct current leakage or breakdown voltage, the gas supplied to the gas discharge tube will, moreover, initiate to ionize and manage until and unless it approaches the impulse spark over voltage. The gadget is now completely operational, and regardless of discharge current, a low arc voltage is maintained. The Gas Discharge Tube Arresters (GDT) will revert to their non-conducting condition after the transient has passed. GDT technology is appropriate as a stand-alone protector or as the first stage in a multi-stage Circuit Protection system because it can handle extremely large surge currents, has extremely high off-state insulating resistance, and has very low capacitance.
How do Gas Discharge Tube Arrestors work?
A gas discharge arrestor is a type of surge-protected device or gas tube. They work the same as a MOV, like the deviation of extra current from the defect or hotline to the ground line. These devices are primarily employed in areas such as industrial plants, power grades, substations, and household applications. Moreover, a gas discharge arrester can be installed in the gas tube using a Power Transformer and mounted on the external side of the wall.
How do I choose a Gas Discharge Tube?
Due to their extremely low capacitance and quick response time, gas discharge tubes are used on DC power lines in a variety of systems. Due to their significantly lower leakage current compared to conventional surge protection components, they can also be employed on AC power lines.
