Comparing IEEE 141 and IEEE 1453: Advancing Flicker Measurement for Modern Power Quality Challenges
This white paper examines the evolution of flicker measurement standards, contrasting the traditional IEEE 141 (GE Flicker Curve) with the advanced IEEE 1453 Flicker Meter standard. It highlights the limitations of the older approach in handling complex, multi-source flicker and demonstrates how IEEE 1453 provides a more accurate, quantitative assessment aligned with human perception. The paper details the technical differences, measurement methodologies, and practical implications for power quality monitoring.
Key topics include:
- Introduction to Flicker and Its Causes
- Overview of IEEE 141 GE Flicker Curve
- Human Perception and Subjectivity in Flicker
- Limitations of Traditional Flicker Measurement
- IEEE 1453 Flicker Meter Standard and Methodology
- Flicker Meter Definitions and Equations
- Comparative Analysis: IEEE 141 vs. IEEE 1453
Why utilities should care:
Accurate flicker assessment ensures compliance with evolving standards, improves customer satisfaction, and supports effective resolution of power quality complaints. Adopting advanced measurement methods enables reliable analysis of complex, multi-source flicker events in modern distribution systems.
