Gas Discharge Tube Arresters (GDT) are designed with a high-voltage arrestee, typically in the range of 25500V, and a low-voltage conductor, typically in the range of -800V. These arrestors are used to limit the maximum voltage surges that may be present in the electrical system. This is done by providing an alternate path for the excess electric charge, or by providing a "shunt", which prevents the system from becoming overloaded. GDTs are often used to protect appliances and networks from power surges and lightning strikes.

The 2037-25-B GDT is typically used for line-to-ground applications, and is commonly used in high-voltage AC distribution systems to protect against lightning strikes and faulty connections. This type of arrester reduces the risk of equipment damage due to over-voltage surges, and allows for a smoother voltage rise in the event of a lightning strike or other overload condition. The 2037-25-B GDT features a low-voltage conductor which is designed to absorb energy and dissipate it over a short period of time. The low-voltage conductor is typically enclosed in a gas-filled tube.

The working principle of a 2037-25-B GDT involves a high-voltage arrestee constructing a connection between the phase wire and ground. When a surge of electricity surpasses the arrestee burning point, the arrestee breaks down, forming a current and voltage limiting variable resistor. When the voltage surpasses theburning point, the arrestee starts to conduct electricity using a spark gap, allowing the remaining surge energy to flow safely to ground instead of the electrical equipment.

When operating properly, the 2037-25-B GDT also reduces the risk of equipment damage due to over-voltage surges, and allows for a smoother voltage rise in the case of a lightning strike or other fault event. The GDT is sized according to the application\'s anticipated voltage rise and flash-over voltage, as well as the temperature, humidity, and environmental factors associated with the application.

The 2037-25-B GDT is also highly reliable and provides a very long lifespan, often lasting for decades without requiring any maintenance. The GDTs also have high thermal resistivity and high electromagnetic compatibility, making them well-suited for use in sensitive equipment such as computers and other electronics. Furthermore, the GDT offers superior surge protection capabilities, allowing it to protect against both direct and indirect lightning strikes.

In conclusion, the 2037-25-B GDT is a highly reliable and effective device designed to protect equipment from power surges and lightning strikes. It has a low-voltage conductor designed to absorb energy and dissipate it over a short period of time, and its operation involves a high-voltage arrestee which forms a connection between the phase wire and ground. By providing an alternate path for the excess electric charge, the 2037-25-B GDT is able to provide superior protection against voltage surges and lightning strikes.
