Flikermeter = Flickermeter
Korošec, Andrej, 1966- ; Voršič, Jože ; Balan, Filip Samo
Kakovost električne energije lahko opišemo z več parametri. Naprave, priključene na omrežje, povratno vplivajo na omrežje; med drugim povzročajo nihanje omrežne napetosti. Nihanje napetosti imenujemo ...niz sprememb ali stalno spreminjanje ovojnice napetosti. Žarnice na žarilno nitko so zelo občutljive na nihanje napetosti, kar se kaže kot spreminjanje svetlobnega toka žarnice s spreminjanjem ovojnice napajalne napetosti. Spremembe svetilnosti svetlobnega vira lahko izzovejo pri človeku neprijeten občutek, kar imenujemo fliker. Temelji na psihofizičnih parametrih človekovega vizualnega sistema, kjer ne veljajo linearne odvisnosti, kar je največja težava pri meritvah in vrednotenju flikerjev. Način merjenja flikerja je standardiziran in temelji na analogni izvedbi. V članku je predstavljen flikermeter, ki je izveden deloma analogno, deloma digitalno.
