Voltage Unbalance Made Actionable in PQCanvass
This white paper explains how PQ Canvass Analytic Reports simplify voltage unbalance analysis, turning field data into clear, standards-based compliance summaries. With automated reporting, utilities can quickly pinpoint the time, phase, and conditions where unbalance occurs—helping engineers reduce investigation time and strengthen grid reliability. Voltage unbalance is one of the most common, and costly, power quality issues in three-phase systems. Even small deviations can reduce motor efficiency, shorten equipment lifespan, and increase losses across distribution networks. Utilities need reliable, fast ways to identify when unbalance is happening, why it’s happening, and how to fix it.
Key topics covered:
- How PQCanvass analytic reports present standardized, compliance-focused results
- Use of NEMA-defined voltage and current unbalance ratios
- Graphs, statistics, and exception lists that highlight unbalance events
- Identifying whether unbalance is load-driven or system-related
- Compliance targets from ANSI C84.1 and typical utility thresholds
Why utilities should care:
Unbalance is more than a nuisance—it drives heating, waveform distortion, and premature equipment failures. PQCanvass analytic reports give engineers a consistent, automated way to detect issues, share results, and plan corrective action. By reducing the time it takes to generate and interpret reports, utilities can act faster, minimize downtime, and maintain confidence in their system performance.
