Gas Discharge Tube Arresters (GDT) are devices utilized to protect electrical circuits from overvoltage caused by lightning phenomena or by pollutant electric signals. The 2036-15-B3LF GDT is a device designed to provide circuit protection for a wide range of applications. This article will outline the application field and working principle of the GDT.

Application Field

The 2036-15-B3LF GDT is designed to be used in outdoor systems subjected to strong transient atmospheric disturbances and direct lightning discharges. It is capable of low capacitance, low leakage, and high attenuation. These features, combined with its lightning surge protection capabilities, make it an excellent choice for power line transmission and distribution systems, telecommunication systems, fire alarms, and medical equipment.

The GDT is capable of providing several levels of protection. It is able to protect the power transmission system from high voltage surges and overvoltages resulting from direct lightning strikes or transmission line faults. Additionally, the GDT can also protect circuits from high frequency conducted disturbances caused by switching or switching transients.

Working Principle

The 2036-15-B3LF GDT works by limiting current and diverting it away from sensitive electronic components. When the overvoltage produced by a transient surge exceeds the breakdown voltage of the device, a spark gap between the electrodes of the GDT forms. This spark gap then creates a high-voltage discharge path between the electrodes, allowing current to bypass the sensitive electronic components.

The spark gap is formed in three stages. In the first stage, the GDT\'s electrodes store energy which creates an electric field. This electric field increases in strength until it matches the breakdown voltage of the device, at which point the second stage of spark gap formation begins. In this stage, ionization of the air in the spark gap begins, allowing current to flow through the gap.

In the third stage, the sparks created by the discharge of current protects the circuit as a surge arrester. The spark gap acts as a barrier between the power line and the sensitive equipment, limiting the current that passes through it and providing surge protection. The current is then diverted through a safe conducting path, protecting the electronic components.

The GDT is a proven technology that has been in use for over fifty years. It is a reliable and cost-effective means of providing protection against lightning surges and other transient electrical disturbances. The 2036-15-B3LF GDT is an example of a high-performance GDT that can be used in a variety of applications, providing reliable surge protection for sensitive equipment.
