Study of Parameters of a 6 kV Distributed Electrical Network in the Tarror Quarry

To ensure uninterrupted supply of electric energy to electric receivers, as well as for safe and reliable maintenance of electrical installations under operating voltage, it is necessary to know the insulation parameters according to which organizational and technical measures are being developed, the use of which allows to obtain positive effects both social and economic. This article discusses the developed methodology for determining insulation parameters in quarry distribution networks. Using the developed methodology, a study was conducted in the “Tarror” quarry, during which the dynamics of changes in the insulation resistance of the network phases relative to the ground was evaluated. Based on the results obtained, it was concluded that it is advisable to carry out such measurements at least a year in advance, which will make it possible to draw reasonable qualitative and quantitative conclusions about the influence of environmental parameters on the insulation resistance of phases of quarry distribution networks relative to the ground.
