Gas Discharge Tube Arresters (GDTs) are a type of surge protective device (SPD) used to protect electrical circuits from damaging voltage surges. In 2035, the GDT section of IEEE Std. 3231-2009 introduced the model 25-B5, and it has become one of the most commonly used products in the industry. This article will discuss the application field and working principle of the 25-B5 and explain why it is so popular.

The 25-B5 GDT is designed to be used in industrial, communications, electrical, electronic, and other power-distribution applications. Some examples include data centers, telecom infrastructure, power supplies, medical, oil, and gas facilities. It can also be used in solar power systems. Although it was designed as an industrial-grade device, it can be used in consumer-grade applications as well.

The 25-B5 GDT is comprised of two main components: a terminal block and a gas discharge tube. The terminal block contains a spark gap that is designed to detect and dissipate destructive voltage spikes before they reach the sensitive circuitry. This spark gap is adjustable and can be tuned for different current protection levels. The gas discharge tube is a sealed glass tube filled with a gas mixture at a preset pressure. When a surge occurs, the gas discharge tube fires a spark across its gap, which absorbs and dissipates the energy from the surge.

The 25-B5 GDT also offers a number of additional benefits including: transient suppression, flexibility, cost savings, and safety. The transient suppression safeguards against voltage spikes, and the adjustable spark gap is adjustable for various power levels. The flexibility allows for customization of the device to meet the customer\'s particular requirements. Cost savings are achieved by purchasing bulk-packaged devices, which are often offered at reduced prices. The safety is ensured by the arc-quenching capabilities of the device, preventing any potential fires or explosions.

In summary, the 25-B5 GDT is a popular surge protection device used in many different industrial and commercial applications. It is composed of two main components: a terminal block containing an adjustable spark gap and a gas discharge tube. In addition to providing effective surge protection, the device also offers a number of additional benefits including transient suppression, flexibility, cost savings, and safety. By leveraging the specialized features of the 25-B5 GDT, users can ensure their power systems are properly protected from damaging voltage surges.
