Where:
Pmax is the maximum power,
Pc is the contractual power,
t1 is the selected time period for the calculation of the AVG/DMD value.
FIXED SELECTION : if, for example, a time interval of 15 minutes has been selected, the instrument will cal-
culate the AVG/DMD value of the measured variable and updates its value every 15 minutes.
SLIDING SELECTION: if for example a time interval of 15 minutes has been selected, the instrument calcu-
lates the AVG/DMD value and updates its value at the beginning after the first 15 values and then after every
minute, thus generating a window whose width is of 15 minutes and that moves forward every minute.
