Electrical Harmonics Testing
Prevent Equipment Damage and Maintain Power Quality
Electrical harmonics—frequency distortions from nonlinear loads such as VFDs, UPS systems, and LED lighting—can quietly degrade equipment performance, cause overheating, trigger nuisance breaker trips, and reduce system efficiency.
Excel Engineering’s electrical harmonics testing & analysis services deliver comprehensive diagnostics and mitigation planning, backed by data. We help you maintain IEEE‑519 compliance, extend equipment life, and reduce energy and maintenance costs—so your facility runs smoother, safer, and more efficiently.
What Is an Electrical Harmonics Testing Analysis?
An electrical harmonics analysis measures voltage and current waveforms, quantifies total harmonic distortion and individual harmonic orders, and identifies resonance points. It helps pinpoint the sources of distortion and assesses their impact on power quality and system reliability.
How Electrical Harmonics Testing Works
We perform a walk-through of your facility to identify potential harmonic sources—like VFDs, UPSs, lighting arrays, and nonlinear machinery— while documenting operational profiles and system layout.
Our technicians use calibrated power‑quality analyzers to capture voltage and current waveforms under typical and peak-load conditions. We measure THD, individual harmonics (up to the 50th order), and phase angles.
Engineers analyze the captured data to evaluate THD levels, identify problematic harmonic orders, and detect resonance risks. Results are benchmarked against IEEE‑519 and utility requirements.
Using simulation software, we model your system’s harmonic behavior. From here, we develop solutions — including passive, active, or hybrid harmonic filters, reconfiguration of transformers (e.g., 12‑pulse), or power factor correction enhancements.
Finally, we compile a comprehensive report with measured data, simulation outcomes, resonance risk mapping, filter design options, cost/benefit analysis, and implementation guidelines.
This process identifies and addresses harmonic distortion thoroughly—protecting your electrical infrastructure, improving reliability, and ensuring long-term efficiency with targeted, cost-effective solutions.
