What is Power Factor?

Inductive Load:
An inductive load is a type of electrical load that makes use of one or more inductors. Inductive loads resist changes in electric current through the inductor. Some examples of inductive loads are transformers, electric motors, electromagnets and electromechanical relays.
Your inductive loads would be your refrigerator, freezer, washer, computer, motor, pumps, etc.

Power factor is the measurement of how efficiently electricity is consumed which is a dimensionless number between 0 and 1. The power factor (PF) in your home or business gets lowered with every inductive load which is added to your system. This increases your electrical consumption because the lower your power factor the more electricity is consumed.

As power factor is measured between 0 and 1, where 1 is the perfect power factor. If the power factor at your home or business is less than 1 then your electrical equipment will demand more power to perform its task - the lower the power factor measurement the higher the demand. This means more energy is being consumed and therefore excessively high electricity bill.

 Power Factor Correction

Correcting your power factor measurement to 1 or as close to 1 as possible can be done by employing power factor correction. PowerMax Power Factor Correction (PFC) units are designed to restore the power factor to as close to 1 as economically possible.

We take great care sizing and installing our PowerMax PFC units, not only to ensure that the power factor is corrected properly, but also to not over-corrected it.

Benefits of power factor correction

  • Power Consumption Reduced
  • Electricity Bills Reduced
  • Electrical energy efficiency improved
  • Extra kVA availability from the existing supply
  • Transformer and distribution equipment losses reduced
  • Voltage drop reductions in long cables
