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...
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...
