Streamlining IEEE 519 Harmonics Compliance with a Simplified Method
This white paper introduces a simplified approach for verifying compliance with IEEE 519-2014 harmonic voltage limits. By leveraging mathematical relationships between total harmonic distortion (THD), individual harmonics, and percentile thresholds, the method allows most sites with low voltage distortion to demonstrate compliance without a full, rigorous analysis. The paper outlines a stepwise procedure that quickly confirms compliance in typical cases and provides guidance for when a more detailed study is necessary.
Key topics include:
- Review of IEEE 519 Limits
- Theory Behind the Simplified Approach
- Simplified Procedure
Why utilities should care:
Adopting this streamlined compliance method reduces the time, complexity, and cost of harmonic analysis while maintaining accuracy. It enables faster resolution of power quality investigations and minimizes unnecessary in-depth studies when voltage distortion is already well within limits.
