English term or phrase: flicker
Definition from NEMA Surge Protection Institute:
Slow variations in voltage that cause the light intensity in a fluorescent light to vary and give the impression of unsteadiness of visual perception.

Example sentence(s):
  • Flicker is a difficult problem to quantify and to solve. The untimely combination of the following factors is required for flicker to be a problem: 1) some deviation in voltage supplying lighting circuits and 2) a person being present to view the possible change in light intensity due to the voltage deviation. The human factor significantly complicates the issue and for this reason flicker has historically been deemed "a problem of perception." grouper.ieee.org
  • Voltage flicker tracking is essential for electric power quality analysis. The instantaneous voltage flicker magnitude, frequency and phase are estimated using Kalman filtering technique. Acta Press
  • This flicker is objectionable only when the magnitude and frequency of occurrence of the voltage drop exceed certain thresholds. cipco.apogee.net

Definition from Tampereen teknillinen yliopisto:
Jännitteen vaihtelut aiheuttavat ärsyttävää valojen valkyntää. Tätä vaikutelmaa kutsutaan
välkynnäksi (flicker).

Example sentence(s):
  • Välkyntä aiheutuu yleensä tasaisesti tai satunnaisesti vaihtelevista isoista kuormista, valokaariuuneista, pistehitsauksesta ja kuljettimien moottoreista. Se aiheuttaa valojen välkyntää sekä ongelmia tietokoneiden toiminnalle ja kommunikaatiolaitteille. - www.abb.com  
  • Elektroninen liitäntälaite poistaa sähköjännitevärinän (-välkynnän) loistevalaisimesta. 50 - 100 Hz:n sähköjännitetaajuus nostetaan 30 000 Hz:iin. - www.adlux.fi
