Résumé	Motor drive efficiency analysis quantifies energy losses in electrical motors and variable frequency drive (VFD) systems, which together comprise the largest industrial electrical load. Methods assess copper losses in windings, core (iron) losses, mechanical losses, and converter losses to identify efficiency improvements and estimate annual energy and cost savings.	Power quality assessment evaluates the suitability of electrical voltage and current waveforms for reliable equipment operation. It measures deviations from ideal sinusoidal waveforms, including voltage sags, swells, harmonics, transients, and imbalance. Comprehensive assessment is critical for ensuring equipment protection, identifying root causes of malfunctions, and optimizing mitigation strategies.
