Why THD-F is the Preferred Metric for Power System Harmonic Distortion
This white paper compares Total Harmonic Distortion referenced to the Fundamental (THD-F) and to RMS (THD-R), demonstrating that THD-F provides more accurate and meaningful measurements for power systems, especially when harmonic distortion is high. THD-R, while common in audio applications, can lead to misinterpretation and lacks sensitivity at higher distortion levels. The paper concludes that THD-F should be the standard for power system analysis.
Key topics include:
- Introduction to Total Harmonic Distortion
- Defining THD-F and THD-R
- Application Differences: Power Systems vs. Audio
- Measurement Limitations and Practical Implications
- Case Studies and Data Visualization
Why utilities should care:
Accurate harmonic distortion measurement ensures reliable power quality assessments, supports compliance with industry standards, and enables effective mitigation of equipment stress and failures caused by high distortion levels.
