Course Description

Flicker is the fluctuation of illumination, which may cause irritation to the eye. The physiological discomfort depends on the amplitude of the fluctuations. Mitigation can be needed to reduce the fluctuations to an acceptable level. As a result of rapid voltage variations, the illumination of most types of lamps will vary. It depends from one person to another whether the respective level of flicker is irritating. Nevertheless, the network operator is responsible for most of the customer complaints. In the module flicker we pay attention to the different causes of flicker; a phenomenon where the voltage varies for a short period of time (<1 second). In addition, the associated costs of flicker are discussed, the options to reduce flicker are shown, and three case studies regarding flicker are included.
