Abstract
The impression of visual unsteadiness caused by the fluctuation of the voltage supplying a lamp (flicker) is a power quality phenomena evaluated according to standards endorsed by both the IEC and IEEE. However, it is widely recognized that flicker measurements provide a correct estimation of the relevant human being annoyance only if a certain light source is considered (60W, 120V incandescent filament-lamp). In recent years, approaches based on the analysis of the light have been proposed. Nevertheless, all these lack of any kind of robust validation. In this respect, this paper presents the results of a study aimed at investigating on the performance of different methods for correlating the annoyance due to flicker with the behavior of some human physiological aspectsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
