3.10 POWER MEASUREMENTS W, VA, VAR, PF AND DPF
This measurement is possible en single-phase or in balanced three-phase.
Reminder :
in DC or AC+DC power measurement, first correct the DC zero in
current (see § 3.8.2, step 1)
For the power factor (PF), the displacement power factor (DPF) and the powers VA
and var measurement is possible only in AC or AC+DC.
