Abstract

The paper deals with the use of Flickermeter and DFT based techniques for the assessment of light flicker and interharmonic distortion produced by arc furnaces. After some recalls on the main interharmonic voltages effects, considerations about the band limitation and sensitivity to interharmonics of IEC Flickermeter are developed. Then, advanced procedures based on the use of DFT spectral analysis are recalled. Finally, experimental results are reported and discussed.
