Schneider Electric PowerLogic AccuSine+ — power quality
Active harmonic compensation, electronic VAR control and load balancing.
Catalog details01 / Product category
Active harmonic filters
Harmonic compensation and load balancing.
Scope and applications
Active harmonic filters compensate harmonic currents produced by nonlinear loads. They are used with drives, electronic supplies and other equipment where measurements establish a need for power-quality improvement.
Products in this category
Sizing requires analysis of the harmonic spectrum, operating modes, network voltage and compensation current. Current-transformer location and polarity are part of the system design. Harmonic mitigation and reactive-power correction are distinct tasks.
Product families
AccuSine PCS+ / PCSn
AccuSine PCS+ addresses industrial applications with demanding electrical conditions. PCSn additionally supports neutral harmonic-current compensation in suitable configurations, relevant to single-phase nonlinear loads.
