Preface
Power quality defines the stability and cleanliness of AC supply delivered to end users. Today, quality degradation is driven primarily by terminal loads-especially non-linear, impact, and unbalanced equipment. While power electronics have improved industrial efficiency, they have also become the dominant source of harmonic distortion and voltage fluctuation in distribution networks.
Widespread use of rectifiers, variable frequency drives, arc furnaces, and railway traction systems introduces severe power pollution: voltage instability, over-voltage, and harmonics. These issues reduce transmission efficiency, cause equipment overheating, vibration, insulation aging, and premature failure. Harmonics can also trigger parallel or series resonances, amplifying disturbances and damaging capacitors and other assets.
The Power Quality Analyzer is the critical tool to identify, measure, and mitigate these problems. By delivering real-time, high-precision data on harmonics, transients, and power factors, it enables targeted correction-improving supply reliability, protecting equipment, and ensuring safe, stable, and economical system operation.
