Gas Discharge Tube Arresters (GDT) are extensively used in high voltage applications due to their excellent performance. The 2020-15T-C2FLF application field and working principle is an important topic to consider in this regard.

The 2020-15T-C2FLF (Fixed Nonlinear Lightning Arrester) belongs to the GDT surge arrester family, and is mainly used for surge protection in industrial and commercial applications. It is designed to withstand high transient voltages triggered by voltage spikes and lightning strikes. The arrester has a very high level of surge current and voltage withstanding capability, and is also equipped with short circuit temperature compensation, making it one of the best choices in terms of cost/performance and reliability.

The operating principle of a 2020-15T-C2FLF Gas Discharge Tube Arrester is simple yet highly effective. The arrester consists of a pair of oppositely charged electrodes, known as a cathode and anode. When a high-voltage surge is detected, current is induced in the GDT and the current rises and then suddenly drops to zero. The sudden drop in current results in an increase in the anode voltage, which in turn triggers the voltage controlled spark gap of the GDT, releasing a spark and discharging the surge energy. As this spark clears, the capacitive discharge current will be re-established, thus resulting in an overall reduction of the long-term energy and voltage being impressed on the protected system.

In addition, the 2020-15T-C2FLF arrester is designed with a unique combination of nonlinear resistors, diode bypass capacitors, and silicon avalanche diodes that provide enhanced protection against external lightning strikes, as well as any subsequent transient over-voltages. The diode bypass capacitors provide short-term energy storage, which helps to ensure that the GDT’s spark gap remains closed and the arrester can still perform its protective function. Meanwhile, the nonlinear resistors reduce the current peaks produced by lightning strikes, thus limiting the amount of energy that passes through the arrester. Furthermore, the silicon avalanche diodes are designed to protect the GDT against over-voltage conditions, and ensure that the arrester is able to remain in its quiescent state when no transient occurs.

In conclusion, the 2020-15T-C2FLF GDT arrester is an effective and reliable product for surge protection in industrial and commercial applications. Its effective working principle consists of a pair of oppositely charged electrodes coupled with a voltage-controlled spark gap, which ensures the safety and reliability of the system. In addition, its combination of nonlinear resistors, diode bypass capacitors, and silicon avalanche diodes allow for the arrester to remain in its quiescent state when no transient event occurs, and significantly reduce the amount of energy that passes through the arrester when external lightning strikes occur.
