CG90SN

CG90SN application field and working principle are categories of Gas Discharge Tube Arresters (GDT).A gas discharge tube (GDT) is an electrical component that is used to protect circuits from high voltage transients. GDTs are installed between source and load, typically at the point of entry to the facility, and will limit the surge\'s magnitude, providing a conducting current path for the surge when it occurs. CG90SN GDTs are primarily used to protect against damage from lightning strikes, electrical surges and other electrical transient events. The core elements of a CG90SN arrester are its two electrodes, the anode and cathode. Both the anode and cathode are fully enclosed in a glass tube, which is filled with a special gas mixture. When the applied voltage exceeds the arrester\'s specified operating voltage, a current will flow between the electrodes, creating an arc of ionized gas. This ionized gas acts as a conducting channel, allowing the current to pass safely through the arrester and dissipating the energy of the transient. When the current is removed after a transient event, the ionized gas dissipates, restoring the GDT back to its relatively high impedance state (above the arrester\'s operating voltage). When selecting the correct GDT for an application, one must consider many parameters, including the manufacturer, voltage rating, current rating, continuous operating voltage, protection level, and maximum fault current rating (if applicable). CG90SN application field of GDTs is wide and varied, ranging from electronic circuitry to industrial machinery. Despite the wide range of applications, the same essential principles dictate their use. For example, the GDTs used in consumer electronics usually have a leakage current rating of 10 mA or less, whereas larger industrial applications may require a higher rating such as 200 mA or more. In this way, the current rating of the GDT can be tailored to suit the specific protective requirements of the application. The working principle of a CG90SN arrester may be summarized as follows. When a transient voltage exceeds the arrester\'s specified operating voltage level, an arc of ionized gas is created between the anode and cathode electrodes of the GDT. Because ionized gas is a low-impedance conductor, this will allow the surge current to pass through the arrester, thereby protecting the circuit or system from damage or malfunctioning. In addition to its simple design, another advantage of the CG90SN GDT is that it can be used both as a stand-alone component and as part of a larger protective system. For example, GDTs can be connected in parallel to increase their current carrying capacity or in series to increase their voltage rating. In summary, Gas Discharge Tube Arresters (GDTs) are an essential part of many electrical circuits, providing surge protection from electrical transients and other voltage spikes. CG90SN GDTs are particularly well suited for circuit protection, as their relatively low cost and easy installation make them a popular choice. The simple operating principle of the GDT is such that once the specified voltage or current rating is exceeded, the ionized gas between the anode and cathode electrodes will provide a conducting current path that will allow the surge current to pass safely through the arrester, while dissipating the energy of the transient.
