Using Harmonic Analysis to Troubleshoot Issues Caused by Power Factor Correction

The growth in electric power consumption during the last two decades has imposed significant strain on an aging power grid in the US. In an effort to encourage more efficient use of the infrastructure, utilties are starting to assess a power factor demand penalty if large customers exceeded a given power factor limit. Power factor correction was the prescription often suggested. Today, companies are choosing electronic motor control systems, incorporating digital frequency conversion, that are becoming the ‘go to’ solution to improve energy consumption. The result can mean that many industrial facilities, built even 15 years ago, are seeing harmonic frequencies which were not part of the original design specification. In this webinar, Jim Chastain will demonstrate the use of the Spectrum Module, the EasyPower harmonics tool, to analyze both system harmonic generation and areas of the plant which could be sensitive to those frequencies.
