DEHN Earthing Tool:
Length of earth electrodes

Calculation of the length of earth electrodes
The DEHN Earthing Tool allows to calculate the length of
earth electrodes as per IEC 62305-3. In this context, the
different types of earth electrodes are important: Founda-
tion earth electrode, ring earth electrode or earth rod. The
soil resistivity is also an important factor for determining the
required length of the earth electrodes.
