Reactive power (with harmonics) of phase (i+1) with i
∈
[0 ; 2].
Reactive powers are calculated using the filtered signals (without harmonics) –
VF[i][j] and AF[i][j] - in accordance with EDF (French national electricity company)
rules or from the apparent and active powers (with harmonics). The choice of cal
-
culation is left up to the user.
Total active power
W[3] = W[0] + W[1] + W[2]
Total apparent power
VA[3] = VA[0] + VA[1] + VA[2]
Total reactive power
VAR[3] = VAR[0] + VAR[1] + VAR[2]
