Try out our power factor correction sizing calculator. Just input the active power in (kW) and the system voltage, the existing measured or calculated power factored and the require power factor you wish to achieve. The calculator will then output the capacitor KVAr required for the system and the minimum current carrying capacity of the supply cable for the capacitor unit.
