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...
Why Does an APFC Panel Keep Switching? Causes of Capacitor Step Hunting and How to Stop It In commercial buildings, manufacturing plants, and distribution substations, Automatic Power Factor Correction (APFC) panels are deployed to maintain target power factor (typically 0.95 to 0.98 lagging) and avoid costly utility reactive power penalties. An APFC panel relies on a microprocessor-based power fa...
Do VFDs Improve Power Factor? Displacement PF, True PF, and Harmonics Explained Variable frequency drives (VFDs) are often described as having a high power factor. That can be correct and still be misleading. A VFD may have little phase shift but draw pulsed input current, creating harmonics that reduce true power factor. The result is a common contradiction: one meter displays a cos φ close t...
Solar Farms Are Paying Hidden Power Factor Penalties Here Is How SVG Stops the Bleeding Solar projects are built to generate active power and reduce electricity purchases from the grid. But as soon as PV production rises and grid import falls, a hidden problem appears: the facility’s reactive power demand does not disappear. The load still needs reactive power, but the active power drawn fro...
