This investigation develops a revisable method for estimating the estimate value of equivalent 10 Hz voltage flicker (DV10) of a DC Electric Arc Furnace (EAF). This study also discusses three 161kV DC EAFs by field measurement, with those results indicating that the estimated DV10 value is significantly smaller than the survey value. The key point is that the conventional means of estimating DV...

The design of a double balanced CMOS downconversion mixer is presented with a novel calibration scheme for pulse injection flicker noise reduction. This self-biasing calibration technique enables the reduction of the mixers’ noise figure by over 20dB at baseband frequencies without any additional reference voltages, manual adjustment, or large inductors. This results in simpler IC testing and m...

The present paper suggests two routines to diagnosis the Flicker by using discrete Wavelet analysis. The routines aim to classify the Flicker voltage limits of studied signals as acceptable or not, according to the standard limits. The first routine depends on the values of details and approximations due to the wavelet analysis. The second depends on separating the residuals (the amount of defo...

Cone signals in the luminance or achromatic pathway were investigated by measuring how the perceptual timing of M- or L-cone-detected flicker depended on temporal frequency and chromatic adaptation. Relative timings were measured, as a function of temporal frequency, by superimposing M- or L-cone-isolating flicker on "equichromatic" flicker (flicker of the same wavelength as the background) and...

Electric arc furnaces (EAFs) are regarded as one of the major sources of voltage fluctuation in power systems which can contribute to a phenomenon known as flicker. One of the most convenient ways to mitigate flicker is employing static VAr compensators (SVCs). By employing prediction models to forecast EAF reactive power SVC performance can be improved very noticeably. In this paper a Grey sys...

The general validity of both the Rovamo [Vision Res. 39 (1999) 533] and Barten (Contrast sensitivity of the human eye, SPIE Optical Engineering Press, 1999), modulation transfer function models for describing flicker sensitivity in vertebrates was examined using published data for goldfish, chickens, tree shrews, ground squirrels, cats, pigeons and humans. Both models adequately described the f...
