Power factor correction calculator/formula:

Following calculator gives the Capacitor sizing required for the power factor correction

Enter current power factor of the system:


Enter target power factor of the system:


Enter load in KW:



Value of capacitor required in KVAR =

How to use the calculator:

  1. Enter current and target power factor required in the above calculator. Power factor value lies between 0 to 1. if you don’t know the power factor of the system, than simply find the same in the multi function meter/energy meter of the incomer of electrical panel.
  2. Than enter load in KW, if you have load ( in amps ) than multiply it with following formula to get the KW Load in KW = 1.732*Line to line voltage of the system*load( in amps)* current power factor
