Introduction. Overvoltage caused by single-phase ground short circuits are the main reason of multiple breakdowns of insulation. Assessment and forecast of overvoltage in SPGSC in the 6–10 kV mains is therefore a relevant task, and the solution to this problem will make it possible to select effective methods and means of limiting overvoltage and improve the conditions of electrical safety. Research aim is to improve the methods of assessing and forecasting overvoltage of arch SPGSC in the 6–10 kV mains of mining facilities. Methodology. This article provides analysis of current hypothesis and methods for the assessment of overvoltages in the single-phase ground short circuit (SPGSC) mode. Currently the hypothesis of Peterson, Peters–Slepyan, Belyakov–Djuvarl does not fully reflect the factors that affect the maximum overvoltage emergence of the single-phase arc ground short circuits in the 6–10 kV mains, because they don’t take into account the capacitive current value of SPGSC, arc combustion conditions, lifetime of SPGSC, inductance of engines and transformers. Results. There have been obtained dependences that show the dependences of frequency with which overvoltage happens from the factors that were mentioned above. The shown dependences can be used for calculation and assessment of overvoltage in the 6–10 kV mains with different neutral modes to justify the need for activities that will protect electrical systems, transformers, electrical engines from overvoltage in the SPGSC mode and considering its lifecycle. Summary. It was established that from the electrical safety positions of 6–10 kV mains with resistive or combined modes of neutrals on mining and extractive facilities create conditions for the safer exploitation of technological complexes, facilities and electrical equipment, because it can reduce maximum overvoltage ratios by half and thus reduce the number of repeated breakdown of insulation in the SPGSC mode.

Introduction. This article provides analysis of electrical traumas and single-phase ground short circuits (SPGSC) in the 6–10 kV electrical systems in the period from 1995 to 2018. It has been shown that reduction in the number of SPGSC will improve electrical safety at coal mines. Research aim is to determine the interrelation between the indicated factors based on the statistical data in the 6–10 kV mains of coal mines according to SPGSC minor and moderate electrical traumas. Methodology. Coal production, development of single-phase ground short circuit and changes in numbers of injuries in the period from 1995 to 2018 have been analyzed making it possible to vividly and qualitatively estimate the dynamics of changes in coal output, the number of SPGSC, electrical traumas and determine the interrelation between these parameters. The discovered interrelation between SPGSC and electrical traumas allows to handle the problem of improving the electrical safety more seriously by means of reducing the number of SPGSC. Results. This article shows the main reasons of single-phase ground short circuit incidence depending on time. The article shows the main ways to lower the amount of single-phase ground short circuit in the 6–10 kV electrical systems of coal mines. Summary. Significant reduction in the number of single-phase ground short circuit in the 6–10 kV electrical systems and, as a consequence, reduction of electrical traumas at coal mines can be achieved by means of effectively limiting switching overvoltage, overvoltage in the mode of single-phase ground short circuit, reaching high selectivity of protection from ground short circuit and improving the quality of electrical energy, and limiting the overloading of electrical equipment and cables.
