RESAP | Soil Resistivity Analysis
The RESAP (Soil Resistivity Analysis) computation module is used to determine equivalent earth structure models based on measured soil resistivity data.
Correctly interpreted soil structures are essential for the analysis of grounding systems, cathodic protection scenarios, electromagnetic induction (EMI) problems, and for the computation of transmission line parameters.
RESAP compares field data to apparent resistivities produced by different soil models, and automatically determines a soil structure yielding a closely matching electric surface response.
In addition, RESAP can be used to approximate the real earth structure using a simplified model based on a reduced number of layers specified by the user. It can also be used to generate limiting soil models, e.g. to ensure that safety requirements are met with a conservative margin despite the fact that the soil structure model exhibits local variations (multiple soil models within the geographical area of interest).
With RESAP, you can develop four fundamental types of soil models:
