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 EM530/EM540 - User manual |23/11/2022 | CARLO GAVAZZI Controls SpA... -
