Gas Discharge Tube Arresters (GDT) are used in electrical systems to provide natural protection against large lightning-induced overvoltages and other transient-voltage spikes. The purpose of the GDT is to act as a protective device between the power source and the equipment connected to it. GDTs work by detecting and diverting sudden variations in voltage away from the power source and into a network of dissipative resistors, while simultaneously limiting the voltage. A popular type of GDT is the 2095-270-BLF.

Application Field of 2095-270-BLF

The 2095-270-BLF GDT is a medium-size thunder and lightning arrester designed for use in electrical equipment subjected to high-voltage protection. It’s suitable for installation along AC distribution systems, in telecommunications systems, and in industrial control systems. When the voltage exceeds the pre-set level, the 2095-270-BLF triggers an internal spark gap, reducing the voltage and protecting the equipment from further damage.

Working Principle of 2095-270-BLF

The 2095-270-BLF GDT works by combining two different types of components. The first is a metal oxide varistor (MOV), which is a device that detects sudden spikes in voltage and diverts them away from the power source. The second component is a spark gap, which acts as a resistor and limits the voltage to an acceptable level, while also providing some protection from lightning.

The GDT has a built-in voltage monitor, which detects when the voltage rises above a certain level. When this happens, the MOV detects the spike and sends it to the spark gap, which then dissipates the energy by splitting the incoming voltage into several smaller, less dangerous pulses. This helps protect the equipment from further damage and provides a more reliable power source.

Conclusion

The 2095-270-BLF GDT is an effective device for providing protection from large lightning-induced overvoltages and other transient-voltage spikes. It combines a MOV and a spark gap to detect and dissipate sudden surge in voltage and protect connected equipment from further damage. The device has been tested to be very reliable and is reliable in providing protection against high-voltage spikes.
