Gas discharge tube arresters (GDT) are widely used to protect electrical and electronic equipment from high voltage surges. A GDT is a device that utilizes a special gas-filled enclosure containing two electrodes. When an excessive voltage is applied, the voltage causes an electric current to flow between the two electrodes, creating an arc. The arc ionizes the gas, creating a plasma state. The energy from the arc is then dissipated, preventing the surge current from continuing to flow.

A popular GDT utilized in electric power systems is the CG2145LS. It is one of the most widely used GDTs, providing fast-acting commutation and excellent radio frequency interference mitigation. The CG2145LS has many unique features that make it a desirable candidate for a variety of application fields. It has low switching losses and hyper fast response times, coupled with low capacitive coupling and low electromagnetic interference (EMI). Its small size also makes it ideal for easily fitting into tight environments.

The CG2145LS is mainly used in power grids, especially those with high-frequency data. These grids often experience frequent power surges, which can damage or destroy sensitive equipment in its vicinity. The GDT can react quickly by ionizing the surrounding gas and dissipating the surge energy in order for it to be safely absorbed. This prevents power surges from ravaging delicate circuits and electrical components.

The working principle of the CG2145LS is simple. The gas chamber is filled with SF6 gas, and there are two electrodes located inside. When the voltage of the power supply is higher than specified, the gas will become ionized, forming a plasma arc. The electric current flowing through the arc will cause a spark, and the resulting heat will dissipate the surge energy. The CG2145LS produces a consistent, low disturbance voltage, making it well suited for power systems with frequent high-voltage disturbances.

The CG2145LS is also widely used in data and communication networks. It is particularly useful in preventing electromagnetic interference (EMI) from high-frequency data, which is generated when surges occur. The GDT acts as a barrier to these disturbances, and the resulting plasma quickly dissipates the surge energy, eliminating the interference and protecting any connected electrical equipment.

The CG2145LS is an effective and reliable solution for a variety of applications, from power grids to communication networks. Furthermore, its compact size allows it to be easily fitted into a wide range of spaces and environments. That makes it the perfect choice for protecting both sensitive equipment and personnel from the harm of power surges.
