This article is devoted to development and application of system of monitoring of electric power quality indicators at mining enterprises. There are considered the questions of provision of quality standards of electric power. There was defined the equipment of mining enterprises, which creates the electromagnetic interferences and makes a negative influence on electric power quality. There are set the tasks of monitoring of quality indicators. There are considered various means of measurement for the control quality. There are shown new standards, which regulate methods of measurement of electric power quality indicators. Underground diamond-bearing rocks' extraction mine was chosen as an object for creation and application of system of monitoring of electric power quality indicators. List of measured characteristics was defined according to requirement of the State Standard 13109-97. There are considered various schemes of connection of analyzer to three-phase circuit. There was carried out the analysis of results of researches and indicators of quality of electric power, obtained during the use of monitoring system.
