SVG Reactive Power Compensation: Beyond PF Correction For decades, plant electrical engineers and facility managers viewed reactive power compensation through a single, narrow lens: avoiding utility low power factor penalty surcharges. Traditional solutions—primarily fixed capacitor banks and automatic power factor correction (APFC) panels—were designed solely to supply bulk capacitive...
AHF and SVG Maintenance Guide for Equipment Lifetime Modern active power quality systems—including Active Harmonic Filters (AHF) and Static Var Generators (SVG)—serve as the first line of defense for critical industrial distribution networks. Unlike traditional passive capacitor banks that contain no active switching semiconductors or microprocessors, active filters are high-density po...
Power Factor Explained: Why Capacitor Banks Overcorrect at Light Load The same capacitor bank that improves power factor during full production can push a facility into leading power factor when the load falls. This overcompensation often appears at night, on weekends, or after large motors stop while capacitors remain connected. A meter may remain close to 1.00, but “leading,” “...
