The formula below will provide the required capacitance in KVAR to improve the power factor of a low voltage electricity supply from the actual target power factor to the target power factor, usually 0.98. Qc = KW x ((tan(cos-1(PF)) – (tan(cos-1(Target PF))) This formula can be used to specify power factor correction equipment. It is important to consider the harmonic distortion of the supply. A supply with high harmonic distortion caused by demand of non-liner loads will require any power factor correction equipment connected to be detuned.

Please share any electrical system issues where high levels of harmonic distortion have been the root cause. Or information where significant system KW losses have been caused by high THD values
