Introduction to Gas Discharge Tube Arresters (GDT):

Gas Discharge Tube (GDT) Arresters, also known as surge arrestors, are devices used to regulate and protect electrical systems from excess voltage. GDTs are designed to protect sensitive electrical and electronic equipment, as well as personnel, from the damaging effects of over voltage. GDTs have been extensively used in power distribution systems worldwide to provide efficient protection against lightning strikes, transients, and other causes of excessive voltage.

2057-07-BLF Application Field and Working Principle:

The 2057-07-BLF GDT arrester is a Type 0 arrester designed for 24 kV AC systems and is capable of handling up to 30 kV of surge current. The 2057-07-BLF GDT arrester consists of a zinc oxide core with a metal housing. This device is designed for indoor and outdoor installation.The 2057-07-BLF GDT arrester is designed to provide protection from high voltage spikes, transients, and lightning strikes that could cause damage to electronic equipment or personnel. This GDT arrester is capable of absorbing pulses as high as 30 kV and has a maximum discharge current of 38 kA. During normal operation, the 2057-07-BLF GDT arrester operates as an open circuit and passes power from the system to the protected load appropriately. However, when a transient voltage spike or lightning strike occurs, the GDT\'s zinc oxide core breaks down and allows the excess voltage surge to be diverted through the arrester\'s path to ground, thus protecting the system from damage.

Conclusion:

The 2057-07-BLF GDT Arresters provide reliable protection to electrical systems against transient and lightning surges. The Type 0 GDT arrester is suitable for use in 24 kV AC systems and is capable of handling up to 30 kV of surge current. This GDT arrester is designed for both indoor and outdoor installation and is capable of absorbing pulses as high as 30 kV and has a maximum discharge current of 38 kA.
