Length of the subperiods:
The length of a subperiod is an integer part of a full hour. The device allows the following
lengths in minutes:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 min
Length of demand period:
The length of the demand period cannot be directly configured. It is defined as the product of
the length of a subperiod and the number of subperiods.
Length

= n • length
subperiod
; n = number of subperiods
Calculation of the power demand and the cumulated power
Arithmetic power demand:
Arithmetic calculation of the power demand referred to the actual length of the demand
period. The arithmetic power demand in the instantaneous period remains constant providing
the power is constant.
Cumulated power:
Cumulative calculation of the power referred to the configured length of the subperiod. The
cumulated power in the instantaneous period increases linearly providing the power is
constant.
The energy can be calculated from the cumulated power as follows:
Energy = (cumulated power) • (configured period length)
