VS230A-B

GDT, or gas discharge tube arresters, are devices that are designed to protect the user from damage to electrical equipment due to overvoltage or short circuiting. VS230A-B GDTs are new high quality products used mainly in medium voltage applications. This article will discuss the specifics of the VS230A-B GDT application field and working principle.

VS230A-B GDT Applications

The VS230A-B GDT is designed for some applicable uses in medium voltage applications. It is advantageous for applications that require quick response time, such as quick clearing down of the overvoltage. The VS230A-B GDT also features outstanding performance against transient overvoltage surges and works well with alternating voltage. The flat surge characteristics of the VS230A-B GDT makes it a suitable solution for power utility distribution in many countries. The VS230A-B GDT has a wide operable temperature range from -50℃ to +125℃ and is completelly UL recognized.

VS230A-B GDT Working Principle

The VS230A-B GDT is made up of a special high-thermal conductive material that can withstand high temperatures. The insulated electrodes are connected to the external leads of the device. When an overvoltage occurs, the insulation between the electrodes is destroyed, resulting in an arc discharge between them. The arc is extinguished by the dielectric material, stopping the flow of current. The arc causes the gas inside the GDT to expand rapidly, pushing the internal pressure of the device high enough to reduce the arc voltage. This activates the fast recovery of the insulation medium, restoring the device to normal. It is important to note that the GDT’s working principle guarantees the absorption of shockwaves and electrical surges which can occur during usage. This effectively eliminates the risk of personnel being injured or equipment damage due to the shockwaves or surges that would otherwise occur.

Conclusion

Overall, the VS230A-B GDT provides excellent protection to personnel and equipment from the effects of overvoltage and transient current surges. The fast response time and wide temperature range make it a great choice for medium voltage applications. Furthermore, the technology behind the GDT ensures that it operates reliably and safely in order to protect against the potential damages that could be caused by overvoltage or transient current surges.
