FIELD: electricity.
SUBSTANCE: grounding device of electrical equipment in soils of high specific resistance is intended for grounding of electrical equipment as protective measures of electrical safety and creation of necessary modes of operation of electrical networks. Physical essence of the coefficient of influence consists in the fact that the spreading current along one, for example, vertical electrode, leads to occurrence of the opposite induction EMF in the adjacent located vertical electrode, thus increasing resistance to spreading current.
EFFECT: reduction of resistance value of grounding device of electrical equipment from climatic effect, as well as reduction of electromagnetic effect from spreading currents in adjacent grounding metal conductors.
