What is Power Factor Correction?

What is Power Factor?

Power factor is the ratio of the real power that is used to do some kind of work and the total power that is supplied to the circuit.

What is Power Factor Correction?

The power factor correction is a method of increasing the power factor of a power supply.

How does Power Factor Correction work?

Well, we won’t burden you with technical diagrams and equations; but to give you a gist – By installing suitably sized switched capacitors into the power distribution circuit, the Power Factor is improved, energy waste is minimized, improving the efficiency, liberating more actual load power from the available supply and saving you money.

When should you use Power Factor Correction?

You should implement power factor correction if you are experiencing the following:

  1. Motor failure
  2. Electrical or electronic equipment failure
  3. Overheating of transformers, switchgear and cabling
  4. Nuisance tripping of circuit breakers
  5. Tripping of fuses
  6. Unstable equipment operation
  7. High energy usage and costs


  • Low-priced
  • Efficient
  • Simple construction


  • Heavy and large size
  • No voltage regulation
  • Restricted range of input voltages
