Make planning easier for yourself with the calculation programmes in the DEHNsupport Toolbox. The four modules help you to evaluate the potential risk for structures. You create a risk analysis and calculate required separation distances and the length of air-termination rods and earth electrodes.
You get a clearly laid out plan with the appropriate protective devices for your project.

With the 4 modules you can determine the potential risk for the building structure, create a risk analysis, calculate the length of air-termination rods, the length of earth electrodes, the separation distances ... and find the appropriate surge protective devices for your project.
With DEHN Risk Tool you determine the potential risk for the building structure and find the suitable class of LPS for your building. You assess the risk and receive
No problem – with the DEHN Risk Tool you plan on the basis of country-specific standards and regulations and the corresponding calculation values.
Note: the standards available in the DEHNsupport Toolbox are based on the standard versions Edition 1 and/or Edition 2 of the IEC 62305-2 lightning protection standard. A risk analysis in accordance with Edition 3 of IEC 62305-2 will be offered in our new DEHNrisk Web tool shortly after the release date of the new version of the standard and is not part of the DEHNsupport Toolbox (expected Q4 2024).
With DEHN Air-Termination Tool, you can calculate the length of air-termination rods as per IEC 62305-3.
The length of the air-termination rods is calculated for different building constellations depending on the class of LPS.
With DEHN Earthing Tool, you can determine the required length of earth electrodes according to the lightning protection standard IEC 62305-3.
The basis for calculation is
DEHN Distance Tool makes it easier to calculate the separation distance using nodal analysis.
Pre-defined building types are available for selection in a picture gallery. This saves you time and makes planning easier.
