ValBrid's Automatic Harmonic Filter (AHF) is an advanced active harmonic mitigation solution designed to significantly reduce total harmonic distortion (THDi and THDv) at the source in industrial and commercial electrical systems. Employing real-time IGBT-based shunt filtering technology, the AHF injects counter-phase currents to neutralize specific harmonic orders such as the 5th, 7th, and 11th, effectively improving power quality. Its modular and stackable design with intermediate current increments allows for precise sizing tailored to current demand and facilitates easy future expansion as electrical loads increase. By minimizing harmonic distortion, it protects critical electrical assets including transformers, motors, and cables from excessive heating and premature aging, while also stabilizing sensitive equipment such as variable frequency drives (VFDs), programmable logic controllers (PLCs), and instrumentation to reduce nuisance trips and production interruptions. The AHF supports businesses in complying with IEEE-519 harmonic standards at the Point of Common Coupling (PCC), thereby helping avoid potential penalties and audits. Additional features include remote monitoring capabilities for power factor, total harmonic distortion, and load unbalance, enabling condition-based maintenance and data-driven commissioning. Ideal for heavy non-linear load environments such as manufacturing plants, steel mills, data centers, and commercial facilities with fluctuating demand, ValBrid’s AHF offers a robust solution for improving energy efficiency, extending equipment lifespan, and ensuring process stability under dynamic load conditions.
