PFA models
Easy connection function: irrespective of the current direction, the power always has a plus sign and contributes to increase
the positive energy meter. The negative energy meter is not available.
PFB models
For each measuring time interval, the individual phase energies with a plus sign are summed to increase the positive energy
meter (kWh+), while the others increase the negative one (kWh-).
Example:
P L1= +2 kW, P L2= +2 kW, P L3= -3 kW
Integration time = 1 hour
kWh+ = (2+2) x1h = 4 kWh
kWh- = 3 x 1h= 3kWh
