A Gas Discharge Tube (GDT) arrester is an electrical protective device that is designed to protect electrical circuits from the harmful effects caused by transient voltage surges. The PMT3 (310) 23006 arrester is a particularly robust type of GDT arrester that is designed to eliminate short-duration electrical disturbances in high voltage power systems caused by lightning strikes or electrical faults. The PMT3 (310) 23006 arrester is also suitable for use in high intensity radio frequency (HIF) and extremely high voltage (EHV) applications.

The PMT3 (310) 23006 arrester is a two-stage GDT arrester that uses a composite structure to ensure optimal circuit protection. The first stage is a nonlinear non-thermically exploding GDT element that is designed to clamp the voltage at a predefined level. The second stage is a metal oxide varistor (MOV) element whose primary purpose is to limit the current flowing through the GDT when the voltage reaches a certain level. The MOV element also diverts the lightning strike current to ground via the GDT element.

The PMT3 (310) 23006 arrester has a number of advantages over other types of GDT arresters. These include its higher capacity for protecting against large voltage surges, a smaller size, improved response time, and increased reliability. In addition, the PMT3 (310) 23006 arrester has been designed to ensure ease of installation, support for the high levels of thermal cycling associated with HIF and EHV applications, and enhanced durability in extreme temperatures.

The working principle of the PMT3 (310) 23006 arrester is relatively simple. When the applied voltage reaches the pre-set voltage level, the GDT element is triggered and the base current is circulated between the anode and the electrode. This lowers the voltage to the GDT electron emission level, thus providing the EHV/HIF circuit with electrical protection. The current then flows through the MOV element and is discharged safely to ground.

The PMT3 (310) 23006 arrester is suitable for a variety of application fields including HIF and EHV power distribution networks, surge protection for electrical systems, and high-voltage overhead power lines. It is capable of providing reliable circuit protection against lightning, switching activity, surges, transient overvoltages, and fault currents. The arrester can also be used in a wide variety of industrial, commercial, and residential settings.

In conclusion, the PMT3 (310) 23006 arrester is a robust and reliable GDT device that is designed to protect electrical systems from the harmful effects of transient voltage surges. Its composite structure ensures maximum circuit protection, while its size and ease of installation make it ideal for a variety of applications in industrial, commercial, and residential settings.
