Gas Discharge Tube Arresters (GDT) are devices used to protect electrical circuits from high voltage transients. The AG20PC152F-H3D is a three-phase gap GDT arrester with two different operating principles. It is used to achieve higher levels of transient protection in a range of different applications.

In its steady-state operation, the AG20PC152F-H3D acts as a conventional surge arrester, providing protection against lightning strikes and other transient high voltage sources. When a transient surge occurs, the arrester operates by diverting the excess energy away from the protected equipment. It does this by using a combination of three parallel gas discharge tubes (GDTs) and two capacitors in order to dissipate the energy. The GDTs act as clamps and the capacitors provide the necessary energy storage.

In addition to its surge protection function, the AG20PC152F-H3D also provides transient voltage protection. This protection is achieved through a combination of two operating principles: peak-clipping and peak-limiting. Peak-clipping mode limits the output of the arrester to a preset maximum voltage, while the peak-limiting mode reduces the arrester output as the transient voltage increases. When used together, these two operating principles enable the arrester to effectively limit the amount of transient voltage that can be transmitted to protected equipment.

The AG20PC152F-H3D is suitable for a wide range of applications, including industrial, renewable energy, oil and gas, and telecommunications networks. It is particularly suitable for equipment which is subject to frequent transient surges, such as power meters and other control systems. The arrester is easy to install and requires minimal maintenance, making it an ideal choice for protection against transient surges.

The AG20PC152F-H3D is designed to meet the needs of both professional and amateur electrical engineers. Its advanced design and reliable performance make it an ideal choice for those looking for reliable surge protection.
