Single-phase ground short circuits in the 6–10 kV mains and electrical traumas in the coal mines
Izvestiya vysshikh uchebnykh zavedenii Gornyi zhurnal, 2020 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.
