Gas Discharge Tube Arresters (GDTs) are protective devices that are used to arrest the effects of lightning, voltage spikes, switching transients, and other power line surges. They are a combination of a spark gap, a relay, and a resistor placed in strategic locations on a power line. They work by allowing a voltage surge to be diverted to the ground instead of flowing directly to the load. GDTs are designed to divert high-energy power surges away from sensitive electrical and electronic components, thus preventing them from becoming damaged or destroyed.

The LT800-A-B is a GDT device designed to provide protection from power line surges. The device is designed to operate in both AC and DC applications. When placed on a power line, the LT800-A-B uses a combination of relay switching, spark gap resetting, and voltage limiting to protect the power line and connected equipment. Its design allows it to detect power line disturbances, such as voltage spikes and overvoltage conditions, and divert them away from the power line and connected equipment. The LT800-A-B works by diverting excess voltage away from equipment. The device consists of two distinct sections – an overvoltage detection section and a spark gap resetting section. The overvoltage detection section contains two relays that detect overvoltage conditions on the power line and close the spark gap to divert the excessive voltage. The spark gap resetting section reset the spark gap when the voltage returns to normal levels. The LT800-A-B\'s unique design also allows it to provide protection from lightning strikes by monitoring voltage gradients on the line. When a lightning strike occurs, it causes a rapid increase in line voltage. The device\'s two relays detect this surge in voltage and quickly close the spark gap, diverting the electrical strike away from the power line and connected equipment.In addition to its overvoltage and lightning protection capabilities, the LT800-A-B also features a voltage limiting resistor which prevents excessive current from flowing through the network and into connected devices. This resistor limits the voltage to a preset value, preventing it from becoming too high and possibly damaging connected equipment.The LT800-A-B is an effective and reliable tool for power line surge protection. Its design provides protection from power line overvoltage, lightning strikes, and also controls current flow to prevent excessive voltage from entering the connected device. By combining the features of a spark gap, relays, and a voltage limiting resistor, the LT800-A-B is an excellent choice for protecting sensitive electrical and electronic components from power line surges.
