AG15P152FB-K2M

Gas Discharge Tube (GDT) Arresters, or surge arresters, are passive electrical components used to protect parallel electric systems from overvoltage disturbances by limiting the voltage that reaches the equipment. GDT arresters provide an ideal solution for protecting electronic systems and devices from high-voltage surge disturbances that are commonly found in power transmission systems, industrial process control systems, and other sensitive applications. The AG15P152FB-K2M is an example of such a device and this article provides an overview of its application field and working principle.

Application field of AG15P152FB-K2M GDT arresters

The AG15P152FB-K2M GDT arrester is designed for use in industrial process control systems, power transmission systems, and other installations where single-phase or three-phase AC systems are cultivated. It has a broad operating voltage range, from 6 kV to 15kV, and a high peak surge current rating (SCR) of 40 kA (40,000 amps). In addition, the AG15P152FB-K2M has a long operational life of up to 20 years, and a low temperature coefficient of -0.5%/K.

Working principle of AG15P152FB-K2M GDT arresters

At normal operating conditions, the AG15P152FB-K2M GDT arrester conducts electrical current in the semiconductor state. When an overvoltage occurs, the current will rise to a certain level and the voltage across the arrester will reach the specified trip voltage. This trip voltage is the maximum voltage at which an acceptable current pulse can flow through the semiconductor material without activating the arrester’s protection function. At this point, the arrester’s protection function is engaged, and the arrester will begin to reduce the voltage across it. The AG15P152FB-K2M has an extremely high surge current rating (SCR), which is the maximum amount of current that the arrester can safely handle without sustaining damage. For this reason, it offers excellent protection against overvoltage disturbances.

Conclusion

The AG15P152FB-K2M GDT arrester is an excellent solution for protecting industrial process control systems, power transmission systems, and other sensitive applications from overvoltage surges. It has a high surge current rating, a broad operating voltage range, and a long operational life. Its working principle is based on reducing the voltage across the arrester when a certain trip voltage is reached. This device is ideal for protecting electronic devices in a range of settings and applications.
