Elimination of disruption on the example of flicker

The paper presents an assessment of the electric energy quality in a industrial plant. The assessment was based on the PN-EN 50160: 2010 - Characteristics of supplied voltage in public power networks. The analysis was based on actual measurements made by power quality recorder Fluke 1760. In the analysis the particular attention was made to the flicker. On the basis of flicker have been identified the disruption coming from the network in which the device operates or from the outside source. Assessment of quality of electric energy will be discussed based on the performed measurements analysis.
