POWER Factor Correction

Power Factor (PF) relates to power quality or efficiency in a power supply system. A PF below 0.9 is low and a PF of 1 (unity) is the optimum. A major cause for low PF in industry and commerce can be traced to items of electrical equipment that may not be working to full rated capacity. High on the list of suspects are air conditioning compressor motors, machines running in idle mode and dated fluorescent lighting systems. This causes electrical inefficiencies to the incoming power supply system.

Supply Authorities recognize PFC as a well established method of reducing electricity costs and other harmful effects which can usually be corrected with the installation of capacitor banks connected across the incoming power supply mains and/or other sections of the power system.

Improving low PF in your industrial or commercial premises will provide the following benefits:
  • Minimize waste in electricity consumption.
  • Reduce KVA power demand and associated electricity costs.
  • Prevent additional Supply Authority penalty charges where applicable.
  • Recover lost capacity enabling the installation of additional equipment.
  • Reduce heat losses in cables and electrical equipment thus increasing life span.
  • Reduce demand on power stations thus reducing Green House Gases.
