Power Factor Correction

WHAT IS POWER FACTOR CORRECTION? 

Power quality is critical to the efficient operation of equipment. One contributing element to power quality is the power factor. Power factor is the ratio of active (real) power kW divided by the total (apparent) power kVA.

Power Factor Correction (PFC) aims to improve power factor and hence power quality, utilizing capacitors to offset usually inductive loads, for example, motors. PFC systems increase the efficiency of the power supply, delivering immediate cost savings on electricity.

Capacitor and electronic means of Power Factor Correction provide well-known benefits to electric power systems. These benefits include power factor correction, poor power factor penalty utility bill reductions, voltage support, the release of system capacity, and reduced system losses.

A high power factor signals maximum use of electrical power, while a low power factor leads to purchasing more power to obtain the same load kW, which you pay for in various ways on your utility bill.

BENEFITS OF INCREASING POWER FACTOR
  • Reduce electrical bills – usually a relatively short payback period
  • Increase (release) system capacity
  • Reduce power losses
  • Voltage improvement

The Return on Investment for Power Factor Correction can be anywhere from 4-6 months depending on the circumstances and the age of your equipment and facility. Results may vary because each client is different.
