Hi -

What is the difference between reducing harmonic distortion and improving the power factor?

Thanks,

Juliane

Hello Juliane

Power factor is the ratio of KW to KVA and is made up of displacement power factor and distortion power factor. If you reduce the harmonic distortion, you will improve the distrotion component of the power factor. If there is a high degree of displacemnt power factor, then the reduction in harmonic distortion may not have much effect, however it is usuall for an individual load to have distortion power factor or displacement power factor rather than both.

Best regards,
