Gas Discharge Tube Arresters (GDT) are an important technology used in electrical power systems. They are effective at limiting the propagation of electrical faults in the system and protecting it from damage caused by lightning disturbances. They are typically placed at the beginning and end of power systems to protect from voltage transients caused by lightning strikes.GDTs are made up of two electrodes, with a dielectric material between them. The dielectric material is made of quartz, mica, or plastic and provides a mechanical insulation between the two electrodes. The electrodes and dielectric form the basis of the GDT and are known as the arrestor body.When normal operating conditions exist, the arrestor body is open and electric current does not flow between the electrodes. During an electrical fault, the electrodes and the dielectric material have a tendency to break down and rather than current passing between the electrodes, a spark gap is created. This creates a spark gap, which is then used to divert the fault current away from the power system.GDTs are generally used in high voltage applications, where the voltage is above 10kV. The high voltage helps to ensure that the spark gap is created quickly, before a significant amount of current can flow through the system.GDTs are used in a variety of application fields. They are used in power substations, power lines, and in many other electrical systems. GDTs have been used to protect electronics and data centers, and to reduce the risk of electrical fires in buildings due to lightning strikes.GDTs are also used in power supply systems for industrial operations, such as in heavy industry, and in motor drives and renewable energy plants. In motor drives, GDTS are used to limit the motor supply voltage and limit the inrush current into the drive during starting. In renewable energy, GDTs are used to protect against lightning strikes and to protect inverters from damage due to overvoltages.The working principle of a GDT is relatively simple. The dielectric material between the two electrodes has a certain breakdown voltage at which it will break down. When the voltage between the electrodes reaches or exceeds the breakdown voltage, the dielectric breaks down, creating a spark gap which acts as a current diverter. The spark gap is designed so that it will break down quickly, before a significant amount of current can flow between the electrodes, thus preventing the system from suffering any serious damage.In conclusion, Gas Discharge Tube Arresters (GDTs) are an important technology used in many applications to protect electrical power systems from damage due to fault currents or lightning strikes. They are relatively simple devices and work by diverting the current away from the power system when the breakdown voltage of the dielectric material between the electrodes is reached or exceeded. GDTs are used in a variety of applications, from power supplies to motor drives and renewable energy plants.
