A study of the parameters of the 6 kV electrical network at Tarrorsky quarry

In order to ensure continuity in the supply of electrical energy to electrical receivers, as well as for the purposes of the safe and reliable maintenance of electrical installations under operating voltage, the insulation parameters according to which organizational and technical measures are being developed needs to be known. The use of such measures will allow ssocial and economic benefits to be achieved.This article discusses the method developed to establish insulation parameters in quarry distribution networks (QDN). Using the methodology developed, a study was conducted in the “Tarror” quarry. During the study the dynamics of changes in the insulation resistance of the phases of the network relative to the ground was evaluated. Based on the results obtained, it was concluded that such measurements should be undertaken at least one year in advance. This will enable reasonable qualitative and quantitative conclusions to be drawn about the influence of environmental parameters on the insulation resistance of the phases of QDN relative to the ground.
