Gas Discharge Tube Arresters (GDTs) are devices which protect electrical and electronic systems from over-voltages caused by transient events such as lightning strikes or power spikes. The 2057-23-BT1LF is a Gas Discharge Tube Arrester designed and manufactured by Teledyne Lecroy for use in a variety of high voltage environments. In this article, we will discuss the application field and working principle of the 2057-23-BT1LF GDT.

The 2057-23-BT1LF GDT is designed for a wide range of applications, including DC overvoltage protection on power distribution lines, surge protection of telephone and communication lines, and overvoltage protection of AC power and signal lines. It has a wide temperature range of operation, with a maximum operating temperature of 105°C and a minimum of -40°C. It also has a high current handling capability, with a maximum current rating of 200A. Additionally, the 2057-23-BT1LF GDT is designed with a low insertion loss, which minimizes the transient voltage drop across the GDT.

The 2057-23-BT1LF Gas Discharge Tube Arrester works on the principle of “gap closure”. The GDT is designed with an insulated gap between two electrodes. Under normal operating conditions, the two electrodes are separated by a large gap and no current can flow between them. When an overvoltage occurs, the gap closes, allowing current to flow through the gap, thus providing protection from overvoltage. The 2057-23-BT1LF GDT is specifically designed with a high gap closure current to ensure that it can effectively protect against high voltage transient events.

The 2057-23-BT1LF GDT is also designed with a self-resetting feature. After a transient event, the GDT will reset itself back to its original state, allowing it to continue to provide protection against future transient events. As an additional safety feature, the 2057-23-BT1LF GDT is equipped with an “off-state” indicator, indicating that the GDT is in an open state and no current is flowing. This ensures that the GDT is working properly and providing protection to the system.

In conclusion, the 2057-23-BT1LF Gas Discharge Tube Arrester is a ruggedly built GDT which is designed for high voltage environments. It can provide protection against transient events such as lightning strikes and power spikes, with a high gap closure current and a wide temperature range of operation. It is also self-resetting and has an “off-state” indicator for added safety and to ensure proper operation. The 2057-23-BT1LF GDT is a reliable and cost-effective solution for providing high voltage transient protection.
