Flicker and Analysis
Flicker is the sensation that is experienced by the human visual system when it is
subjected to changes occurring in the illumination intensity of light sources. The primary
effects of Flicker are headaches, irritability and, sometimes, epileptic seizures.
IEC 61000-4-15 and former IEC 868 describe the methods used to determine Flicker
severity. This phenomenon is strictly related to the sensitivity and the reaction of
individuals. It can only be studied on a statistical basis by setting up suitable experiments
among people.
The EPM 9450/9650 meter with Software Option A (base configuration) offers Flicker
monitoring and analysis. The EPM 9650 meter with Software Option B has EN50160/
IEC61000-4-30 Power Quality Compliance analysis for Flicker and other power quality
measurements. (Refer to the licensing and order code information in Chapter 2.) Refer to
the GE Communicator Instruction Manual for additional information.
