Identify Harmonic Resonance Faster with PQ Canvass 3D Graphs
This white paper explains how to visualize harmonics using PQ Canvass’s 3D Waterfall graphing tool. By moving beyond simple THD numbers, PQ Canvass’s interactive 3D waterfall graphs expose resonance, distortion, and shifting harmonic orders in ways that make problems easier to spot and quicker to solve. From nonlinear loads like VFDs and EV chargers to capacitor bank resonance, harmonics can cause costly stress on transformers, motors, and capacitor banks. The right tools help you quickly see which harmonics are the problem, when they occur, and where they come from—before they lead to equipment damage or compliance issues.
Key topics include:
- How 3D waterfall graphs show order, magnitude, and time together
- Spotting harmonic shifts and resonance events in real-world systems
- Using stripchart graphs for deeper, targeted investigation
- Applying PMI recorders with PQ Canvass for live and historical harmonic analysis
Why utilities should care:
As today’s grids take on more EVs, capacitor banks, and nonlinear loads, harmonics are no longer edge cases—they’re everyday challenges. Simply measuring THD isn’t enough. PQ Canvass’s 3D harmonics graphs let you see trends at a glance, confirm the source of problems, and reduce troubleshooting time. The result: fewer surprises, extended asset life, and the data you need to demonstrate compliance.
