DEHN Air-Termination Tool

The DEHN Air-Termination Tool can be used to calculate the length of the air-termination rods depending on the class of LPS as per IEC 62305-3.


To determine the height of the air-termination rods, drawings are required which must be produced depending on the class of LPS. To facilitate this process, the software includes different calculation constellations. The aim is a technically correct external lightning protection system. In this context, it is important to dimension the protected zones depending on the height of the air-termination rod.
