Abstract (en)
[origin: WO2004046702A1] The invention relates to a method for determining properties of soil, especially the humidity content thereof. Said method comprises the following steps: a temporary or permanent electromagnetic field is generated in at least one electroconductive overhead line by applying an alternating voltage, in such a way that the at least one field penetrates the soil; at least the running time of the wave packet used to generate the temporary electromagnetic field, or a change in the alternating voltage parameters of the field between at least two points interspaced in the longitudinal direction of the overhead line, is measured; and the at least measured running time and/or the measured change in the alternating voltage parameters between the at least two points in the at least one electroconductive overhead line are compared with standard values.
