  • If the energy distribution company imposes penalties for reactive power consumption, improving power factor correction is a typically passive energy saving measure. It takes immediate effect after implementation and does not require any changes to procedures or staff behaviour. The investment involved can be recouped in less than a year.
See Power Factor Correction for further details.
  • Many types of equipment (variable speed drives, electronic ballasts, etc.) and computers generate harmonics within their line supply. The effects produced can sometimes be significant heat and vibration potentially reducing the efficiency and service life of such equipment as capacitor banks used for power factor correction. Harmonic filtering is another typical passive energy saving measure to consider.
See Power harmonics management for further details.
