Gas Discharge Tube Arresters (GDT) are used to protect sensitive electrical equipment from potentially damaging electrical surges due to lightning strikes. The ST-0800-BLT-STD is a type of Gas Discharge Tube Arrester (GDT), designed to protect electrical systems from transient voltage changes due to weather-related or other environmental influences. This type of surge protection device is designed to provide a path for the current to flow in a restricted area, that is different than the primary circuit being protected.

The ST-0800-BLT-STD application field is mainly used in electricity distribution systems, outdoor equipment cabins, control systems, computer systems, telecommunications equipment, signal collection, and control system applications. Its main working principles is that during normal operation, the device acts as an insulator, preventing the flow of electrical current. When a high-level voltage caused by lightning strikes occurs, the device automatically switches from its insulating state to a conducting state, providing a path for the electrical current to be safely directed away from the sensitive electronics, protecting them from potential destruction due to the transient voltage.

The device contains a GDT component that acts as a negative temperature coefficient thermistor, providing the necessary negative temperature coefficient characteristics. A resistor connected in parallel with the GDT helps reduce the surge current that passes through it, and the resistor is also used to limit the current that passes through the GDT during normal operation. The device also contains an inductor that is used to absorb the energy from the surge and dissipate it.

The working principle of the ST-0800-BLT-STD is based on its ability to detect transient voltage changes due to lightning or other environmental influences and to quickly switch from its normal state of insulation to a conducting state, allowing for the electrical current to be safely redirected away from the sensitive electronics. This protects the equipment from potential destruction due to the transient voltage.

The combination of the GDT, resistor, and inductor helps to quickly and safely redirect the high-voltage surge away from the sensitive equipment, thus protecting it from harm due to transient voltages. Other features of the ST-0800-BLT-STD include a low surge leakage current, protection from unpredictable or sporadic power surges, a wide operating temperature range, and high reliability due to its robust construction and self-resetting capabilities.

Ultimately, the ST-0800-BLT-STD is an effective and reliable surge protection device that can protect sensitive electronic equipment from electrical surges due to lightning and other environmental influences. The device is designed to quickly and safely redirect the current away from the delicate electronics, thus protecting them from potential damage due to the transient voltages.
