Research of Grounding Systems of Electrical Complexes in the Conditions of Permafrost Soils

The article conducted a study of the effectiveness of the grounding systems of industrial electrical systems in permafrost conditions. On the basis of comparison of regulatory documents in the field of protective grounding, the main approaches to the design of protective grounding devices were considered, in relation to the features of the geographical location of the object and the characteristics of the soil. The technologies and possibilities of using classical and electrolytic grounding methods are studied. As a result of modeling, the scheme of rational protective grounding of electrical installations in the conditions of the working enterprise has been proposed.
