Unlock Deeper Insights from Daily Power Quality Profiles with Standard Deviation Analysis
This white paper explores how overlaying standard deviation on Daily Profile Graphs in the Canvass power quality portal reveals critical variations in voltage and current data that average values alone can obscure. By visualizing both the mean and the variability of readings, users gain a more nuanced understanding of power quality events and system behavior throughout the day, enabling more effective analysis and troubleshooting.
Key topics include:
- Daily Profiles Overview
- Limitations of Averages in Profile Graphs
- Standard Deviation Overlay: Method and Value
- Closer Analysis with Stripcharts
Why utilities should care:
Standard deviation overlays highlight hidden fluctuations in voltage and current, enabling earlier detection of anomalies and more accurate assessment of system stability. This leads to improved reliability, targeted maintenance, and optimized operational decisions.
