Pinpointing Voltage Sag Sources Through Advanced Data Capture Techniques
This white paper explores effective methods for identifying the origins of voltage sag by leveraging detailed voltage and current data. It emphasizes the importance of proper recorder settings, such as waveform and RMS capture, interval graphs, and histograms, to distinguish between customer load and supply-side issues. Real-world examples illustrate how analyzing these parameters can reveal the root causes of voltage fluctuations, enabling more accurate diagnostics and targeted solutions.
Key topics include:
- Key Recorder Settings for Voltage Sag Analysis
- Interval Data and Event Correlation
- Waveform Capture Techniques
- RMS Capture for Detailed Analysis
- Using Histograms for Voltage Regulation Assessment
Why utilities should care:
Accurate identification of voltage sag sources reduces misdiagnosis, improves power quality, and streamlines troubleshooting. Leveraging current and voltage data enables faster resolution of customer complaints and supports proactive grid reliability improvements.
