PFC models
For every measuring interval time, the energies of the single phases are summed; according to the sign of the result, the
positive (kWh+) or negative totalizer (kWh-) is increased.
Example:
P L1= +2 kW, P L2= +2 kW, P L3= -3 kW
Integration time = 1 hour
+kWh=(+2+2-3)x1h=(+1)x1h=1 kWh
-kWh=0 kWh
