Visualize and Diagnose Power Quality Issues with Harmonic Bar Charts
This white paper explores the use of harmonic bar charts in Provision software for analyzing voltage and current waveform harmonics up to the 51st order. It details how these charts provide an immediate, visual snapshot of harmonic content, enabling users to identify and investigate power quality issues efficiently. The paper explains the benefits of examining harmonics directly from captured waveform data, describes key metrics such as THD, TIF, and K-factor, and outlines best practices for leveraging bar charts to optimize troubleshooting and memory usage.
Key topics include:
- Introduction to Harmonic Bar Charts
- Accessing Harmonic Bar Charts in Provision
- Understanding the Harmonic Bar Chart Display
- Key Harmonic Metrics: THD, TIF, and K-Factor
- Best Practices for Harmonic Analysis
- Memory Optimization and Diagnostic Workflow
- Generating and Interpreting Harmonic Analysis Reports
Why utilities should care:
Harmonic bar charts enable rapid identification of waveform distortion, streamline root-cause analysis, and optimize recorder memory usage. Their visual and numeric insights support effective monitoring, troubleshooting, and long-term maintenance of power distribution systems.
