Gas Discharge Tube (GDT) arresters are devices that are used to provide protection against lightning strikes, surges, static electricity, and other overvoltage phenomena in power and communications circuits. GDTs are designed to divert and reduce the voltage before it can do any damage to the circuit. They are also available in a variety of shapes and sizes to fit any application.The 2028-25-C2LF arrester is a three-hole GDT designed for limited circuit protection. This arrester is constructed with three gas tubes—two for voltage threshold and one for current threshold. The arrester’s two voltage-threshold gas tubes act as spark gaps for voltage protection, while the current-threshold gas tube allows for current limitation. When an overvoltage condition occurs, the arrester begins to conduct, creating what is known as a spark gap. This spark gap limits the voltage on the circuit by diverting it from the protected circuit to the ground. The size of the spark gap is determined by the intensity of the overvoltage. The spark gap created by the 2028-25-C2LF arrester is limited to 2-5 kV for normal operational voltages in power systems and communications networks. This arrester is also designed to withstand up to 20 kV peak power surges and limit short-circuit currents to less than 3 kA.The current-threshold gas tube serves two purposes—it allows greater fault current protection and extended response times. When the arrester senses an overvoltage condition, the spark gap formed by the two voltage-threshold gas tubes will clear it quickly. However, in the case of a sustained overvoltage such as a lightning strike, the current-threshold gas tube will continue to conduct the fault current, providing extra protection to the circuit. When the fault current has dissipated, the current-threshold gas tube will also break the circuit and return the arrester to its quiescent state.The 2028-25-C2LF arrester is designed for use in power and communications circuits with an operating voltage of up to 6 kV and a maximum peak power surge of 20kV. It can be installed in a variety of applications, including transformer towers, distribution lines, and cable networks. The arrester is also designed to provide effective protection for both AC and DC circuits.Overall, the 2028-25-C2LF arrester is a well-designed device for use in a variety of high-voltage applications. It is designed with three gas tubes to provide reliable protection against overvoltage conditions, while the current-threshold gas tube ensures maximum protection in the event of prolonged overvoltage. The arrester is able to provide reliable protection with limited response time, making it ideal for a variety of applications.
