    Energy Quality And Efficiency Of An Open Pit Mine

    Oct 09, 2014 This paper presents a solution to energy quality problems in an open pit mine distribution system. Specifically, mine shovel operation is frequently disrupted by energy quality issues. A number of alternative approaches to deal with this problem include the use of reactive power compensator technologies (i.e. passive filters electronically switched capacitor banks and static VAR compensators ...
