Gas Discharge Tube Arresters (GDT), one of an advanced level of surge protection devices, is designed with a high arc extinction capability and have low operating and follow current values. A typical GDT is often made of porcelain, having a length ranging from 1 to 6 inches, which may contain anywhere from 2 to 8 tubes filled with an inert gas. The conductive particles are being provided to the active Region, allowing a surge to travel through the tube and getting grounded upon contact.

BPG255NPE is a silicon-oxide-based GDT, is designed as a general-purpose and medium-voltage surge arrester for use in a variety of applications, such as Telecommunications Equipment, Electrical Meters, Lightning Protection, and Motor Control Circuit Surge Protection.

The BPG255NPE GDT is designed with a spark gap which is made of stainless steel. It has a low spark gap impedance, a low follow-on current value, and a high breaking capacity. The spark gap is filled with an inert gas mixture that is maintained at a specific pressure, allowing the GDT to improve repeatability and reliability. It also has a high surge current capacity and excellent protection to transient over-voltages.

The excellent thermal stability of the sparking gap allows it to dissipate energy rapidly, leading to improved follow-on current performance. The spark gap also helps reduce control level voltages and spark over problems. The spark gap also has a self-cleaning feature which helps reduce contamination in the spark gap.

The BPG255NPE GDT is designed to protect low voltage equipment from short-term over-voltage conditions. It is typically used for low voltage applications between 0.2 and 0.3 kV. The GDT works by using the spark gap to limit the surge energy that flows into the protected equipment. The spark gap in the GDT also prevents backflow of the surge energy by re-directing it to the ground. This allows the protection of the protected equipment from damage.

The BPG255NPE GDT is usually installed in close proximity to the protected equipment. It must be connected to the common return lead of the protected equipment, which is typically the low voltage cable for most applications. The screw terminals of the GDT must then be connected to the low voltage cable. This will allow the surge current to travel through the GDT and be discharged to the ground.

The BPG255NPE GDT is an excellent solution for medium voltage surge protection applications. It is designed with a spark gap that is highly efficient at handling surge energy and is able to withstand multiple transient overvoltages. The BPG255NPE GDT is also highly reliable and has an extended life expectancy. It is an easy to install solution that provides excellent protection against surges and is ideal for low voltage applications.
