This lot, SB72, features a Schneider Electric AccuSine+ active harmonic filter, used to improve power quality and protect sensitive electrical systems from voltage distortion and poor power factor.
The AccuSine+ system continuously monitors load current and dynamically compensates for harmonic content, neutral current, and reactive power, ensuring optimal performance and compliance with IEEE 519 standards.
It is installed in the PF-1 Electrical Room, adjacent to the main distribution equipment, and serves as part of the facility’s advanced electrical management infrastructure for high-efficiency operation of automation, HVAC, and lighting loads.
