Gas Discharge Tube Arresters (GDT) are a type of overvoltage protection device used in high-voltage power systems. The GDT works by suppressing high-voltage transients caused by lightning strikes or other sources of electrical overvoltage. The GDT also provides protection against intermittent overvoltage, which occurs when there is a power outage and the voltage level increases above the normal operating range. GDTs can be used to protect electrical equipment such as motors, electronic controls, and circuit breakers.The 2038-20-SM-RPLF application field is the protection and limiting of high frequency voltage transients and noise associated with electrical power systems. It is intended for use in the following applications: motor control, circuit protection, construction industry protection, and communication systems. The 2038-20-SM-RPLF GDT can be used in two-wire, three-wire, four-wire, and five-wire systems.The working principle of a GDT is based on the electric gas discharge principle. The GDT contains a cylindrical glass tube that is filled with a mix of rare gases and a coupling agent. The tube is sealed except for two metal electrodes, one at each end, separated by the rare gas mixture. When an electrical potential is applied to the electrodes, electrons are accelerated across the tube, creating an electric current. As the electric current passes through the tube, the rare gas molecules become ionized and a spark is created. The spark dissipates the excess voltage, allowing the overvoltage to be safely discharged.When an overvoltage occurs, the 2038-20-SM-RPLF GDT reacts with a rapid current rise. The GDT’s spark gap is designed to be wide enough so that its arc voltage is low and its breakdown voltage is high. This allows for a rapid discharge of the transient overvoltage and helps protect the connected electrical components.The GDT also has a low burning voltage, which is the maximum voltage allowable without damage to the circuit. This helps safeguard electrical devices from permanent damage due to an overvoltage condition. Once the transient voltage is dissipated, the GDT automatically returns to its normal, non-conductive state.In conclusion, GDTs provide an effective solution to suppress high-voltage transients by providing a fast, safe, and consistent overvoltage protection. It does this by quickly discharging the transient voltage and protecting sensitive components from permanent damage. The 2038-20-SM-RPLF GDT has a wide range of applications and is designed to be reliable and efficient in high voltage power systems.
