Sažetak
One of the important aspects of the power quality in electric power distribution and transmission networks is estimation of the light flicker caused by voltage variations. International standards governing design of power quality recording devices and various standards for evaluating power quality include model-based estimation of visual discomfort using UIE/IEC Flickermeter. Newer standards also use assessment of Rapid voltage changes (RVC) - computationally simplified but yet less precise model. Both models are based on the discomfort level reported by test subjects, which limits them on perceivable disturbances. However, many studies indicate that light flickering may cause number of physiological effects even when affected individual is not aware of the disturbance: headaches, eyestrain, decreased performance, interference with cortical processes, seizures etc. Some of these potential effects require further detailed research, but all of them should be considered as a topic in future development of the power quality standards.
