- Page 14 power factor, is no longer the only component constituting the overall power factor. Harmonics do increase apparent power and thus decrease the overall power factor. That is the Total Power Factor is actually affected by both phase-shift angle and harmonics, and is given by the expression: In order to improve overall system power factor, nowadays power-system engineer needs to address both phase-shift and harmonics problems.
