If AC_Meter.Generator_X is configured - the calculation is the sum of all phases (Y=1,2,3): (AC_Meter_Generator_1.V_LY * AC_Meter_Generator_1.I_LY * AC_Meter_Generator_1.PF_LY) divided by 1000.

Else, the calculation is the sum of all phases (Y=1,2,3):

The availability time is calculated by accumulating the time between records where the relevant asset was connected. The time will be accumulated only if the time difference between the subsequent records is less than 15

...

minutes. In addition, if the calculated availability value is larger than the Data Availability value, the value will be assigned

...

to the Data Availability value.
