Abstract :
The paper presents an analysis of the voltage fluctuations caused by interharmonics and its influence on luminous flux fluctuations of used combinations of fluorescent lamps and ballasts. One of the analysis results is a concept determining light sources sensitivity to such disturbing type based on frequency components utilization. Further a complex measured data file of sensitivity curves in various combinations of fluorescent lamps and ballasts are pointed. Measured and compared combinations include various types of fluorescent lamps, various wattages, modes of operation of the ballast and its specific designs and dimensioning of circuit elements etc.
