Measurement of Soil Resistivity
The soil resistivity is the geological and physical quantity for calculation and design of
earthing systems. The measuring procedure shown in Figure 10 uses the method
developed by Wenner (F. Wenner, A method of measuring earth resistivity; Bull. National
Bureau of Standards, Bulletin 12 (4), Paper 258, S 478-496; 1915/16).

1. Four earth stakes of the same length are positioned into the soil in an even line and
with the same distance "a" to each other. The earth stakes should not be hammered
in deeper than a maximum of 1/3 of "a".
