Unlocking the Hidden Impact of Harmonics on Power Factor and System Efficiency
This white paper explores how harmonics from modern nonlinear loads degrade power factor differently than traditional inductive loads. While phase shifts from inductive loads are easily corrected, harmonics increase apparent power without contributing to real power, making correction more complex. The paper details the mechanisms, measurement techniques, and mitigation strategies for addressing harmonic-induced power factor reduction.
Key topics include:
- Power Factor Definition
- Real Power
- Power Factor with Undistorted Waveforms
- Power Factor with Distorted Waveforms
- Mixed Loads
Why utilities should care:
Understanding the distinct effects of harmonics on power factor is crucial for optimizing system efficiency, reducing losses, and selecting effective mitigation strategies. Addressing harmonic distortion helps maintain power quality, lowers operational costs, and prevents equipment stress.
