Harmonic Analysis Using a Digital Twin of The Electrical System
We construct a digital twin of your electrical system’s key elements and run computer simulations to take virtual measurements throughout the power system for our harmonic analysis reports. We use numerous probes at all critical points where data is required. We quickly and cost-effectively model your system. We do not need to enter your facility!
What we need: a single line electrical diagram, ratings of power sources and major equipment, and your objectives.
What we provide: a written summary report with key wave-forms and harmonic data to the 100th harmonic, explanation of the results and our recommendations to meet your power quality objectives.
Industries served: We have provided harmonic analysis reports for hundreds of power systems including water and wastewater treatment facilities, oil/gas pipelines, oil/gas drilling, and pumping, irrigation systems, casinos, mining, induction heating, arc furnaces, industrial facilities, food processing facilities, data centers, office buildings and more. We can offer our standard analysis & report format or follow the report requirements identified in your engineering specification.

Information required for Harmonic Analysis
In most cases, we can perform a complete report from our office, eliminating the cost of an on-site visit. Typically, we will need the following information:
- Single line diagram with ratings of power sources & major loads
- Explanation of your power quality problems or concerns
- Power quality measurement data if available
- Operating conditions to be considered
- State your power quality objectives
Please Call us at 1-262-618-2403 or Email us or Visit our Contact Us page.
Following the guidelines of IEEE-399, we can perform a system analysis of single or multiple loads and provide you with a meaningful report complete with our explanation of the problem and the recommended solution. Drawing from decades of experience and using computerized simulation software we are able to analyze disturbance sources, quantify the magnitudes of current and voltage at any point in a circuit and evaluate wave-forms and harmonic spectra throughout a system. Our in-depth reports can include waveform analysis, harmonic data, power factor, DC bus stability, motor voltage, resonance conditions, and more.
