In the paper, theoretical and experimental studies including measuring of the electricity quality indices at mining enterprises were made. The evaluation of the efficiency of the applied means of high-harmonic compensation was fulfilled. The proposals to create the system for continuous monitoring of power quality indices were developed. Electrical devices of surface and underground complexes of mines connected to distribution networks 6 kV and used in mining and processing of diamondiferous ores were considered as the research objects. The results of installation of the monitoring system of electric power quality indices at electric drives and frequency converters of some process units were studied. Technical and economic analysis was carried out, and the guidelines concerning the improvement of energy efficiency of frequency-controlled electric drives were formulated.
