EN Very often, voltage fluctuations can cause a decrease in power quality. It is possible to improve this quality by changing the characteristics of the fluctuation source and/or the supply circuit. To do so, it is necessary to find the source of a given fluctuation and determine its properties. The problem-causing loads are most often identified through the analysis of fluctuation amplitude variations. Less popular is a method that compares the variations of the current with the variations of the voltage fluctuation indices. In this paper, both methods are described, and their properties are compared.
