Unlocking Accurate Flicker Measurement with IEEE/IEC Flickermeter Standards
This white paper details the implementation of IEEE/IEC flicker measurement standards in modern power quality monitors. It explains the signal processing chain, including gain control, demodulation, filtering, brain response simulation, and statistical classification, to objectively quantify voltage fluctuations that cause perceptible light flicker. The paper also outlines recommended flicker limits and data collection strategies, enabling consistent, repeatable, and actionable flicker assessments.
Key topics include:
- Overview of Flicker
- Flickermeter Defined
- Flicker Signal Processing Chain
- Data Collection
- Flicker Limits
- IEEE 1453 Recommended Flicker Limits
Why utilities should care:
Accurate, standardized flicker measurement enables objective assessment of power quality issues, supports regulatory compliance, and helps prioritize mitigation efforts. Consistent data collection and interpretation reduce customer complaints and improve reliability of service delivery.
