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...
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...
SVG and AHF Components: What Determines Accurate and Long-Term Performance? A 400 V plant may install two power-quality cabinets with the same rated current and expect the same result. Months later, one follows peak load while the other derates, produces more acoustic noise, or leaves compensation error at the point of common coupling (PCC). The difference lies in the sensing chain, ...
