Variable Frequency Drives (VFDs) have become essential in modern industrial systems. They provide accurate motor speed control, reduce mechanical stress, and can significantly improve energy efficiency. However, there is another side of VFD technology that is often underestimated: harmonic distortion. In low-voltage distribution systems, a large number of VFDs can become an important source of har...

In low-voltage power factor correction systems, detuned reactors are widely used together with capacitor banks to prevent harmonic amplification and protect capacitors. Among the most common configurations, 7% and 14% detuned reactors serve different purposes and require different capacitor specifications. A 7% detuned reactor typically creates a tuning frequency of approximately 189 Hz in a 50 Hz...
