Unlocking Symmetrical Components from Any PQ Recorder's Stripchart Data
This white paper presents a practical method for calculating positive, negative, and zero sequence symmetrical components from any power quality (PQ) recorder or dataset that provides fundamental magnitude and phase angle data. By leveraging basic trigonometry and a structured workflow‚ using ProVision software and a spreadsheet template‚ users can derive these components even when they are not natively recorded. The approach enables effective voltage imbalance investigations and customer contribution analysis, regardless of the original data source.
Key topics include:
- Configuring a Recorder to Record 60Hz Magnitudes and Phases
- Using the PMI Symmetrical Components Sheet
Why utilities should care:
Enables rapid, accurate voltage imbalance analysis and customer impact assessment using existing PQ data, reducing the need for specialized equipment and streamlining investigations with accessible tools and workflows.
