The products > Reactive energy compensation > General information > Advantages of a good power factor

  

A good power factor is:

  • A high cos φ (close to 1)

  • or low tg φ (close to 0)

 

A good power factor makes it possible to optimize an electrical installation and provides the following advantages:

  • no billing for reactive energy (EDF "Tarif Vert" rate subscribers),

  • decrease in the subscribed power in kVA (EDF "Tarif Jaune" rate subscribers)

  • limitation of active energy losses in cables given the decrease in the current conveyed in the installation,

  • improvement in the voltage level at the end of the line,

  • additional power available at the power transformers if the compensation is performed in the secondary winding.
