Mastering Interharmonic Recording: Practical Approaches for Accurate Power Quality Analysis
This white paper demystifies the complexities of interharmonic measurement and analysis in power quality monitoring. It details the IEC 61000-4-7 framework, explores efficient recording strategies using the Revolution and ProVision tools, and offers best practices to balance data granularity with memory constraints. Recommendations are provided for setup, data capture, and analysis workflows, enabling effective identification and resolution of interharmonic-related power quality issues.
Key topics include:
- Understanding Interharmonics and Standards
- Measurement Types and Data Aggregation
- Recording Methods with the Revolution
- Configuring Interharmonic Recording
- Recommended Recording Strategies
- Analyzing Interharmonic Data in ProVision
Why utilities should care:
Effective interharmonic analysis enables early detection of complex power quality disturbances, supports compliance with evolving standards, and optimizes data management. Streamlined workflows reduce unnecessary data collection, improving investigative efficiency and system reliability.
