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).
