Harmonic Analysis

Get to the root of power quality issues.

Harmonics in electrical currents are an important indicator of poor power quality. They cause overheating in electrical components and can damage sensitive equipment, which affects your manufacturing process and assets.

If you're experiencing problems with power quality, Fleming Controls and Power Specialties have trained technicians available to help. Our experts can monitor your system for harmonics, voltage dips and other disturbances. We'll help you identify your power quality problems, reduce nuisance trips, extend equipment life and improve the overall reliability of your system.

Intermittent power quality disruptions can originate from inside your facility or from the electric utility system. Our professional technicians will recommend the most cost effective measures to reduce the number and severity of these disturbances. Poor power quality can impact manufacturing processes and system components, especially sensitive electronic equipment.


  • Solves process disruptions due to power disturbances
  • Reduces economic effects of poor power quality
  • Decreases maintenance costs
  • Identifies disturbances originating with the electric utility
  • Identifies wiring and grounding improvements
