5.2.17 Power Factor

The power factor (Pf) is the relation between I
The power factor for 3-phase supply:
The power factor indicates the extent to which the frequency converter imposes a load on the mains supply. The lower the power factor, the higher the
I for the same kW performance. In addition, a high power factor indicates that the different harmonic currents are low.
