GTCS23-351M-R01-2 Circuit Protection

Gas Discharge Tube Arresters (GDT)

Gas Discharge Tube Arresters (GDT), such as GTCS23-351M-R01-2, are devices designed to protect electrical equipment from transient overvoltages arising from lightning, switching operations, or other disturbances. As such, GDTs are used as surge protection devices in a variety of different industries in order to safeguard vulnerable electrical systems from damage.

Application Field

GDTs can be found in many industries ranging from telecommunications to home appliance manufacturing. In the telecom industry, GDTs are used to protect sensitive communication equipment from lightning and other overvoltages. As most modern telecommunication systems are vulnerable to damage from transient overvoltages, GDTs are often installed in order to minimize the potential for costly repairs and downtime resulting from an overvoltage event. In the manufacturing industry, GDTs are used to protect automation and industrial control systems from overvoltage events. GDTs are also used in residential applications, such as in electrical panels, power strips, and battery backup systems, to help protect home appliances from damaging power surges.

Working Principle

GDTs, such as the GTCS23-351M-R01-2, work by creating a short-circuit path for transient overvoltages. A GDT uses a sealed glass tube filled with a gas, usually air, and a special metal electrode. The metal electrode is connected to the ground side of the system, forming one pole of the GDT. The other pole of the GDT is connected to the power line. When an overvoltage travels along the power line, a spark is created across the electrodes, creating a low impedance path to ground. This allows the transient energy to be diverted away from the sensitive equipment, thus protecting the system from potential damage.

GDTs are often used in series with a capacitor. This helps to reduce the peak overvoltage seen by the system, further improving the protection afforded by the GDT. The capacitor helps to reduce the rate of rise of the transient waveform, which in turn helps to prevent damage to the sensitive equipment.

Conclusion

Gas Discharge Tube Arresters (GDTs), such as the GTCS23-351M-R01-2, are an important component in protecting electrical equipment from transient overvoltages. GDTs can be found in a wide variety of industries, ranging from telecom to manufacturing and residential home electrical panels. GDTs work by creating a low impedance path to ground for transient energy, allowing that energy to be safely diverted away from the sensitive equipment. GDTs are often used in combination with capacitors in order to further reduce the peak overvoltage seen by the system.
