Gas Discharge Tube Arresters (GDT) are a form of electrical surge protection devices. They are used to protect electronic equipment from damage due to electrical surges or voltage spikes caused by lightning strikes, power line faults, and switching operations. GDTs are made up of a gas discharge tube, a diode, and a resistor. These components work together to provide surge protection, reduce noise, and limit the voltage that can be applied across a circuit.

2027-42-SM-RPLF Arresters are GDTs that are specifically designed for use in outdoor applications. These arresters have a higher temperature rating than other GDTs, and are capable of withstanding temperatures up to 85°C. They also have a higher voltage rating (up to 8kV) and shorter life span. 2027-42-SM-RPLF Arresters are designed to provide a medium level of protection against electrical surges in all medium voltage installations.

The working principle of the 2027-42-SM-RPLF Arrester is based on the GDT. When a surge voltage is applied, the resistor limits the current passing through the diode, while the gas discharge tube becomes illuminated with the additional energy introduced by the surge. The discharged gas within the tube serves as an insulator, preventing the surge voltage from entering the protected equipment. When the surge voltage decreases, the current flowing through the diode increases, and the illumination in the tube is quickly extinguished. The discharge gas then reabsorbs the voltage and the protected equipment is returned to its original state.

In addition to providing surge protection, 2027-42-SM-RPLF Arresters are also capable of preventing electrical noise from entering into the protected circuit. Electrical noise can cause erratic operation of electrical equipment, and is particularly damaging to sensitive electronic equipment. The diode integrated within the 2027-42-SM-RPLF Arrester prevents the noise from entering into the protected circuit, preserving the integrity of the electronics.

The 2027-42-SM-RPLF Arrester is designed for use in medium voltage environments. It is suitable for overhead transmission lines, as well as in HV/LV substations, power transformers, switchgear, electrical installation works, electrical control systems, and other protective applications. This Arrester provides a cost effective and reliable form of surge protection, allowing equipment to be protected from electrical surges while also eliminating electrical noise.

In summary, 2027-42-SM-RPLF Arresters are Gas Discharge Tube (GDT) Arresters that are specifically designed for outdoor medium voltage applications. The working principle of the Arrester is based on the GDT, and it is capable of limiting the voltage applied across a circuit, preventing electrical surges from reaching the protected equipment, and eliminating electrical noise. This Arrester is suitable for a variety of applications, providing an effective and reliable form of surge protection.
