Capacitor Banks vs. Active SVG: Which Power Factor Correction Is Right for You? When your electricity bill suddenly spikes — or your utility sends a power-factor penalty notice — a common fix is to install power factor correction (PFC). For decades, that meant one thing: capacitor banks. Today you have a second, modern option: the Static Var Generator (SVG). Both i...
Certificate Documentations in Power Quality Selection: Meaning and Guide A procurement engineer receives an Active Harmonic Filter quotation with a compliance certificate attached. The certificate names a product family, but the quotation specifies another voltage, current rating, enclosure layout, ambient condition, and feeder arrangement. The correct question is not “Does the suppli...
A fixed capacitor bank is often the most economical way to correct power factor — provided the load stays reasonably steady. When motors cycle or production changes by shift, it may overcompensate overnight and undercompensate at peak. An Automatic Power Factor Correction (APFC) panel switches capacitor steps as demand changes; a Static Var Generator (SVG) adjusts reactive power continuously...
Quick Answer An APFC panel is not simply permitted or forbidden on generator power. Compatibility depends on generator capacity, the power factor of the load that stays online, the size of each load step, harmonic distortion, available short-circuit capacity, governor and excitation response, the generator manufacturer’s limits, and the logic inside the APFC controller. On many standby syste...
