THE FEASIBILITY OF USING ELECTROLYTIC GROUNDING IN SOILS WITH HIGH RESISTIVITY

Abstract

The high resistivity of the soil leads to many problems, among which the most significant are a decrease in the level of electrical safety, high material costs and an increase in the amount of excavation work when using a traditional grounding device. In this regard, it is necessary to resort to various technical measures, for example, the device of vertical earthing devices of increased length, the device of remote earthing devices, if there are places with lower resistivity near the electrical installation, laying wet clay soil in trenches around horizontal earth      ing devices, the use of artificial soil treatment in order to reduce its resistivity, etc.

The purpose of this article is to assess the feasibility of using electrolytic grounding in areas with high soil resistivity. In addition to this, it is necessary to choose the most advantageous offer among the manufacturers of these products widely known in this environment, as well as to make a visual comparison of the proposed grounding with standard ones and to identify the advantages of using this type of grounding when designing a new traction substation.

The article presents the calculation results for the design of a traction substation in the Severobaikalsky district, according to which a number of advantages of using electrolytic grounding can be identified when comparing with a standard grounding device, the specificity of the application conditions, and the economic feasibility of this type of grounding. It is also proposed to use electrolytic grounding in the design of new traction substations in order to increase the electrical safety of service personnel.
