Power Factor Correction · 6 min read · Published 2026-07-17 · Updated 2026-07-17
APFC panels are widely used for stepped capacitor correction, while static var generators provide fast dynamic reactive power compensation for rapidly changing loads.
APFC panel strengths
APFC panels are cost-effective for many factories where load changes are moderate and capacitor step correction can maintain the required power factor.
SVG strengths
Static var generators respond quickly to changing reactive power demand and are useful for welding, cranes, VFD-heavy plants and other rapidly changing loads.
How to choose
Choose based on measured load behavior, required response time, harmonic environment, penalty structure, available panel space and future expansion.
FAQs
Is SVG a replacement for APFC?
In dynamic load applications it can be, but APFC remains suitable for many stable industrial loads.
Which is faster?
Static var generators provide much faster dynamic compensation than conventional stepped APFC panels.
