Unlocking the Importance of Crest Factor in Power Compatibility Assessments
This white paper explains the concept of crest factor, its calculation, and its critical role in evaluating load compatibility with synthetic AC sources like inverters and UPS systems. It highlights how high crest factor loads can challenge power sources, discusses the distinction between crest factor and total harmonic distortion (THD), and provides a practical example of measuring crest factor in a real-world scenario.
Key topics include:
- Crest Factor Defined
- What Does Crest Factor Show Us
- Crest Factor Rating
- Crest Factor vs THD
- Measuring Crest Factor
Why utilities should care:
Understanding crest factor helps ensure compatibility between loads and synthetic AC sources, preventing overloads and shutdowns. Accurate crest factor assessment aids in equipment selection, system reliability, and proper derating, especially with modern electronic loads.
