Gas Discharge Tube Arresters (GDT) are considered one of the most reliable and efficient techniques to protect electrical equipment from transient over-voltages. GDTs provide protection with minimal load-break interruption and have a long lifespan with minimal degradation. The 2057-13-BLF GDT is specifically designed for mounting in outdoor medium voltage networks and other applications requiring surge protection. This article will discuss the application field and working principle of the 2057-13-BLF GDT.

The 2057-13-BLF GDT is an excellent solution for high voltage applications. It is designed to protect outdoor medium voltage networks from lightning strikes, switching, and voltage jumps. It has an operating voltage range of 12 to 36 kV and a maximum rated continuous working voltage of 34 kV. It is also capable of providing protection against multiple strikes and has an excellent pressure limitation performance culminating in a long service life.

In terms of its application field, the 2057-13-BLF GDT can be used for overhead lines, solar inverters, substations, distribution lines, and telecom networks. It is also suitable for other transition over-voltage applications. It is designed to be straightforward to mount and is available in a variety of sizes, making it suitable for a range of applications. It is also certified to UL4704, making it both safe and reliable.

The 2057-13-BLF GDT works on a gas-filled chamber and uses pressure differences between the atmosphere and the electrodes of the GDT. The GDT utilizes a dielectric that interrupt the current when it reaches a certain threshold. When an overvoltage occurs, the gas is ionized and the current flows through it, triggering the arrester to open and release the current. The dielectric then reverts back to its initial state, providing a secondary protection from any remaining transient effects.

The 2057-13-BLF GDT also utilizes a zinc-oxide varistor component which acts as an additional protection layer. The varistor helps to eliminate surges along the line and makes sure that the system is protected from any possible damage. It also helps to reduce power losses and improves the over-voltage protection performance of the GDT.

In conclusion, the 2057-13-BLF GDT is an excellent choice for protection in outdoor medium voltage networks. It has a long lifespan and provides exceptional pressure limitation performance. It requires minimal load-break interruption and is available in a variety of sizes, making it suitable for a range of applications. It utilizes a gas-filled chamber and zinc-oxide varistor components to protect the system from transient over-voltages, ensuring that the system is kept safe and reliable.
