Introduction

Gas Discharge Tube Arresters (GDT) are a type of electrical device used to protect electronic circuits and systems from high voltage. GDTs generally protect by providing a low impedance path to ground when the voltages exceed a predetermined level, allowing the current to bypass the protected device or circuit and be directed to ground. VS800A-B are a type of GDT specifically developed to provide the greatest protection possible against high frequency energy, and to ensure safe and reliable operation in environments with very high voltage. This article will discuss the application field and working principle of the VS800A-B GDT.

Application Field of VS800A-B

VS800A-B GDT are designed to provide maximum protection against high frequency signals and surges. They are often used in potentially hazardous or highly sensitive environments, such as commercial buildings, smart grid systems, telecommunications systems, and medical equipment. The VS800A-B GDT is also well-suited for applications requiring high-voltage protection with rapid response times.The VS800A-B GDT can be used in both AC and DC systems. It can operate in temperature ranges from -40 to +70°C and offers a high operating voltage of up to 24kV. Additionally, the VS800A-B GDT is UL and FCC certified, ensuring a safe and reliable operation in multiple environments.

Working Principle of VS800A-B

The VS800A-B GDT is designed to provide superior protection against high frequency energy. When the voltage in the system exceeds the predetermined level of the VS800A-B, the GDT is triggered and the current is diverted to ground. This process is known as a “tripping” mechanism.The tripping mechanism of a VS800A-B GDT is based on the principle of a spark gap. A spark gap is a physical space between two electrodes that is filled with a gas. When the voltage across the electrodes rises to a certain level, an electric spark or arc is created, allowing the current to jump across the gap. The VS800A-B GDT uses a gas-filled spark gap to achieve the same effect.When the voltage in the system exceeds the VS800A-B’s tripping threshold, the electrodes of the GDT will become ionized, forming a conducting path between them. The current travelling through the system will then be diverted to ground, protecting the system from damage.The VS800A-B GDT is designed to be a fast-responding protection device. A typical GDT can respond to high voltage conditions within one microsecond, ensuring that the protected circuitry is safe from any dangerous levels of voltage.

Conclusion

Gas Discharge Tube Arresters (GDT) are a type of electrical device used to protect electronic circuits and systems from high voltage conditions. The VS800A-B GDT is specially designed to provide superior protection against high frequency signals and surges. It is often used in potentially hazardous or highly sensitive environments such as commercial buildings, smart grid systems, telecommunications, and medical equipment. The working principle of the VS800A-B GDT is based on the principle of a spark gap, which is triggered when the voltage in the system exceeds the predetermined level. The VS800A-B GDT is UL and FCC certified and offers a rapid response time of 1-2 microseconds.
