2.- METER CALCULATIONS
2.1.- Nominal Voltage
2.2.- Nominal current
2.3.- Apparent power
2.4.- Active power
2.5.- Reactive power
2.6.- Power factor
2.7.- Maximum demand
The maximum demand is calculated from the instantaneous power of each second. This
power is averaged over a period of integration (15 minutes), obtaining MD
