Active Harmonic Filters vs. SVG: Choosing the Right Power Quality Solution In modern electrical networks, non-linear loads—from variable frequency drives (VFDs) and UPS systems to LED lighting and EV chargers—are ubiquitous. These devices distort the ideal sinusoidal current waveform, generating harmonic currents that pollute the entire facility's power system. Left unchecked, h...
Static Var Generator SVG for Power Factor Correction A fabrication plant in Monterrey replaced its capacitor bank contactors every quarter. The 800 kvar bank tripped on overcurrent whenever five spot welding machines fired within the same second, and the utility meter recorded a lagging power factor of 0.78 — the plant paid a penalty surcharge on every invoice. The capacitors were not...
