The grounding system of the subsurface should ensure the safe and reliable operation of power systems, and guarantee a human being's safety in the situation of grounding fault in the power system. The safety of power apparatus in the subsurface can be reached by decreasing grounding resistance and grounding potential rise of subsurface. This paper presents a method based on the design of an artificial neural network(ANN) model for modeling and predicting the relationship between the grounding resistance and temperature-humidity in the subsurface.

The accurate measurement of soil resistivity and earthing system resistance is fundamental to electrical safety. However, geological and meterological factors can have a considerable effect on the accuracy of conventional measurements and the validity of the measurement methods. This paper presents optimization method of dc resistivity data acquisition system using ERT.
