Introduction: Gas Discharge Tube Arresters (GDT) are an important component of electrical and power systems that protect against lightning impulses, damaged and overvoltage surging. The 2036-07-B2LF GDT is a peak current limiting arrester used for protecting MV power systems from lightning and other high-voltage transients. In this article, we will discuss the application field and working principle of the 2036-07-B2LF GDT.

Application Field: The 2036-07-B2LF GDT is designed for overhead and substation uses to protect power transformers, switchgears, and distribution and transmission lines. This arrester can be used in applications ranging from 3 to 27kV. It can be used in industrial, utility, and commercial power systems. The arrester is also suitable for outdoor and indoor use in harsh environments, as it is able to operate from -40 °C to +60 °C.

Working Principle: The 2036-07-B2LF GDT operates by using a gas-filled discharge tube that acts as a lightning and surge protector. When subjected to a lightning impulse, the gas-filled discharge tube conducts the transient current, thus providing the protection. The arrester is designed to withstand high transient current and to limit the peak current to be within the acceptable range. The arrester is equipped with a spark diverter protection that protects it from short-circuiting during a lightning event. The discharge tube is composed of a dielectric material with a pre-set voltage threshold. When the voltage exceeds the threshold, the dielectric material breaks down and conducts the current, thus limiting the current to a safe level. The discharge tube can be recharged after each surge event and is designed to remain inactive when there is no surge.

Conclusion: The 2036-07-B2LF GDT is a reliable and efficient peak current limiting arrester that can be used to protect MV power systems from lightning and other high-voltage transients. This arrester is suitable for use in various environments, from industrial to commercial use, and can withstand high transient currents. Its gas-filled discharge tube is used to conduct the transient current, thus providing the protection, and a spark diverter protection prevents short-circuiting during a lightning event. The discharge tube can be recharged after each surge event.
