Harmonics Measurement

Why Harmonics are Important

High levels of harmonics can cause power quality problems and accelerate the aging of impacted equipment like transformers. Industrial loads are often the source of harmonics problems and high levels of solar and EV charging on a feeder can make harmonics worse.  Harmonic solutions at substations help but line sensing with advanced analytics offers a new cost- effective, easier to deploy approach for measuring harmonics along feeders.

How It Works

Sentient Energy’s solution for harmonics measurement is the MM3ai System. The system combines advanced analytics, intelligent line sensors, and software to provide utilities with accurate harmonics measurements along feeders. The MM3ai System generates a weekly report of feeder harmonics activity using a redlight approach for areas  with elevated harmonics.

Key Features

With high-fidelity waveform data from MM3ai line sensors and proprietary algorithms developed by utility industry data science experts, the MM3ai System’s weekly harmonics report identifies feeders with elevated harmonic levels. The MM3ai System includes:

  • MM3ai Line Sensors for quarter point visibility on eight feeders
  • Ample software with managed cloud deployment
  • Deployment and ongoing support including report training & 1-hour monthly meetings
  • Software updates
  • Cellular fees
  • Warranty

Harmonics Measurement Benefits

Information from the weekly harmonics measurement report enables utility reliability teams to identify feeders with elevated levels of harmonic disturbances. They can then isolate sources of harmonics problems on those feeders and provide real system data to justify and direct actions to mitigate problems.

Customer satisfaction is enhanced when harmonics problems are eliminated. Reliability and asset life are improved, as unaddressed elevated harmonics will  prematurely wear out equipment.
