GTCT38-401M-R10

Gas Discharge Tube Arresters (GDT) are electrical components designed to protect electrical power systems from transient overvoltage conditions. GDTs are effective against lightning strikes, switching operations in electric power systems, electrostatic discharges, and other environmental conditions. GTCT38-401M-R10 is a gas discharge tube arrester manufactured by Chinese manufacturer, Shanghai GT Avionics Electronic Co., Ltd., and is widely used in various electrical power systems.

GTCT38-401M-R10 is a three-element gas discharge tube arrester. It consists of a main element, a secondary element, and a series element. The primary element is made up of a low-capacitance gapless gap gap tube. This element is responsible for diverting any high voltage/current surges away from the secondary element. The secondary element is made up of a low-capacitance varistor over which the current is diverted. The series element consists of a resistor which adds resistance to the current and thereby reduces the power released by the arrester. The buffer between the main and the secondary elements also helps in limiting the current from getting too high.

GTCT38-401M-R10 is a stable, reliable and self-healing arrester and it can handle up to 130 kV peak in an AC environment, and has a response time of less than 200 µs. It is suitable for operation in a temperature range of -45oC to +50oC. All of these features make it suitable for a wide variety of power system applications that require surge protection, such as substations, power plants and industrial locations.

The working principle of the GTCT38-401M-R10 is as follows: when high voltage or current overloads occur, the primary element of the arrester conducts, diverting the current to the secondary element, where it is vaporized. This vaporization is followed by an increase in the voltage across the varistor. The varistor then conducts, limiting the magnitude of the overvoltage and thereby protecting the power system components. The current is then dissipated through the resistor element, which helps in further dissipating the energy.

In conclusion, GTCT38-401M-R10 is an excellent, reliable and efficient gas discharge tube arrester from GT Avionics Electronic Co., Ltd. It has excellent voltage/current protection capabilities, making it suitable for a wide variety of power system applications. It also has a fast response time, and is stable and self-healing.
