Gas Discharge Tube Arresters (GDT) Application field and working principle

Gas Discharge Tube (GDT) Arresters are used to control and smooth voltage and current surges in high voltage power delivery systems. The GDT Arrester has the ability to absorb and control extremely high voltage and current spikes, that can potentially injure people and damage electrical and electronic components.GDT Arresters are also commonly known as Spark Gap Arresters (SGAs), Surge Diverters or Surge Limiters.When a high-voltage surge enters the arrester, a spark will form across an air gap between two electrodes. The spark, in turn, creates a highly conductive path between the two electrodes. This path conducts the electricity and dissipates the surge into the ground. This process is known as clamping.The SL1021B150RG is a GDT Arrester that is designed to protect electrical and electronic systems against high-voltage transients. It is a gas-filled surge protector which is designed to become an electrical conductor when its pre-set threshold is exceeded. It can be used to protect consumer electronics, computing equipment and communications systems from electromagnetic interference (EMI).The SL1021B150RG has a peak current rating of 150 kA, a peak voltage rating of 10 kV, and an energy absorption rating of 100 Joules. It is a ozone-safe unit, and is UL certified.The SL1021B150RG also features an inhibit connector, allowing the device to be disabled when not in use. This can be used to prevent wear and tear on the device, thus prolonging its life.The application field of the SL1021B150RG ranges from industrial, military, and transportation to consumer electronics, wherever overvoltage or EMI protection is required. Its proven design makes it perfect for high energy applications such as motor starters, remote control transformers, radio frequency interference, and high-voltage lightning protection.The working principle of SL1021B150RG is based on the GDT technology. A high voltage surge will cause a spark to form across an air gap between two electrodes. This spark creates an electrical current, which is conducted away from the system, thus dissipating the surge. The amount of surge that is absorbed by the arrester is determined by its peak current rating, peak voltage rating, and energy absorption rating.The SL1021B150RG also has built-in safeguards and LED indicators to signal when the device has been activated. It has an inhibit connector, to disable the device when not in use, thus prolonging its life and preventing wear and tear. The SL1021B150RG is both UL approved and ozone-safe, making it an ideal choice for a range of high-voltage protection needs.Overall, the SL1021B150RG GDT arrester is a reliable and highly-effective solution for a range of high-voltage protection needs. Its proven design and reliable functioning make it perfect for industrial, military, transportation, and consumer electronics applications. Its inhibiting connector and LED indicators enable it to be monitored and enabled/disabled according to the operational requirements. Therefore, the SL1021B150RG is an ideal choice for protection against electrical surges and EMI.
