Abstract	This paper presents research of phenomena in the soil around activated grounding system considering behavior of fields and their correlation, as well as reflection of these appearances on main grounding parameters. If through grounding system flows current with significant intensity then generated heat in the soil around grounding electrode will cause heat rise in that soil. Under specific circumstances this heating causes evaporation of moisture in the soil, so that resistance and temperature, considering mutually strong positive feedback, start to rise progressively. This kind of unstable condition causes spiral breakdown, which can be followed by extremely high values of soil resistance, inadmissible high values of grounding system potential and finally by high values of touch voltage and step voltage. Also, a model of fields' correlation shall be tried to be established in the soil around grounding system at the flow of high amplitude currents through that grounding system.
