How one should calculate the power loss due to harmonics? A typical 6 pulse VFD with diodes in rectifier module produces about %30 THD (Total Harmonics Distortion). An "Active Front End" VFD reduces the harmonics to %4 or lower. Is it safe to say that, if you are running a 1000HP motor, using an "Active Front End" VFD saves you about %24 of 1000HP in electric bills?
I am just looking or a ballpark estimate.
