Gas Discharge Tube Arresters (GDT)

Gas Discharge Tube (GDT) Arresters are the most important type of surge protection device for high frequency transmission and communication systems. They offer protection from transient overvoltages caused by lightning strikes and other sources. GDT arresters are designed to absorb high peak currents generated by the sudden surge of energy, and it is capable of providing sustained protection from multiple, closely spaced surges.

PMT3(310)40004 Application Field and Working Principle

The PMT3(310)40004 is a type of GDT arrester developed by Phoenix Contact. It is designed for use in transmission, communication and data processing systems in low voltage (up to 2kV). It can be used in a wide variety of applications, including power plants, substations, industrial switchgears, ß-DIN rail mountable housing, and telecom systems.The basic working principle of a GDT arrester is to provide a path to ground for the transient current generated by a lightning strike or other electrical surge. This path is formed by a series of arc-quenching or spark-gap cells. The cells are filled with an inert gas, such as argon or nitrogen, and have electrodes that create an arc when the voltage exceeds the preset breakdown voltage of the tube. The arc then dissipates the energy across the gas, providing a safe passage for the current to the ground. The PMT3(310)40004 arrester has an adjustable breakdown voltage that can be set to the specific needs of the application. The adjustable breakdown voltage allows the arrester to be used in a variety of voltage levels, from just above the normal working voltage to well above the normal breakdown voltage.The PMT3(310)40004 arrester also has an adjustable spark gap that provides a very low voltage fault alarm and trip function. This low voltage alarm allows for early detection of any spark activity and can be used to trigger alarm devices or trip circuit breakers.The PMT3(310)40004 arrester also has a surge quenching circuit that provides surge protection for both outgoing and incoming surge energy. This quenching circuit helps to protect the customer\'s systems from the full force of the incoming and outgoing surge.Finally, the PMT3(310)40004 arrester also has a built-in monitor circuit that helps to identify any malfunctioning arc-quenching or spark-gap cells. This provides a safe, convenient way to monitor the performance of the arrester and ensure that it is operating within expected parameters.In summary, the PMT3(310)40004 is a robust and reliable GDT arrester that provides reliable surge protection for a wide range of high frequency transmission and communication systems. It is easy to install and can be used in a variety of applications, from power plants to telecom systems. With its adjustable breakdown voltage, low voltage fault alarm, surge quenching circuit, and built-in monitor circuit, it is an ideal solution for any application requiring reliable surge protection.
