Unlocking Accurate Interharmonic Measurement with Advanced Recording Tools
This white paper explores the growing challenge of interharmonics in power distribution networks due to non-linear loads like VFDs and inverters. It details how PMI's Revolution recorder and ProVision software enable precise recording, measurement, and visualization of interharmonics, offering practical setup recommendations and compliance with IEEE 519 standards.
Key topics include:
- Defining Interharmonics
- Causes and Effects of Interharmonics
- Recording Interharmonics with the Revolution
- Data Management and Memory Optimization
- Visualization and Analysis with ProVision
- Best Practices and Recommendations
Why utilities should care:
Interharmonics can degrade power quality, causing equipment heating, filter overloads, flicker, and communication interference. Advanced monitoring and analysis tools help identify, quantify, and mitigate these issues, supporting compliance and system reliability.
