What is the relationship between displaced power factor, true power factor and current harmonics.

Hello normanwarrenjr

True power factor is due to both displacement power factor and distortion power factor.

Distortion power factor is caused by the presence of harmonics, displacement power factor is due to the presence of reactive circuits.

Therefore if current harmonics are reducced displaced power factor and true power factor come closer together? Could we also say that a true indication of harmonics filtering or harmonics reduction is when the DPF and the TPF are almost the same? Can this mathamatically by proven?

Hello normanwarrenjr

Yes, if the distortion powerfactor was 1 (no distortion = no harmonics) then the true power factor would equal the displacement power factor.
