how is quality measured in iron ore mine

Improved power quality and productivity in an iron ore mine by means of SVC In 2009, an SVC supplied by ABB was commissioned in the LKAB iron ore mine at Kirunavaara in the north of Sweden. The SVC, rated at 0-35 Mvar at 6.3 kV, has the purpose of improving power quality at the 145 kV Point of Common
