Flicker measurement has improved dramatically with the advent of the flicker measurement techniques described in IEEE-1453/IEC61000-4-15. It is a feature found in many power quality monitors that makes flicker measurement more objective, quicker and more thorough. This paper presents a description of the method described and the standards to implement flicker measurements.

This white paper includes:

• Overview of flicker
• Flickermeter defined
• How does it work?
• Block 1 - gain control
• Block 2 - demodulation
• Block 3 - weighing filter
• Block 4 - brain reaction
• Block 5 - statistical classification
• Data collection
• Flicker limits
• IEEE 1453 recommended flicker limits to avoid complaints
