For example, if 15 minutes is selected, the demand calculation will be performed and the demand
values will be updated every 15 minutes.
With a sliding window setting, the Power Xpert Meter provides a rolling average; you select the
interval period and the subinterval period. For example, if you select 15 minutes as the demand
interval and 5 minutes as the subinterval, the demand will calculate every 5 minutes using the 3
subinterval values (15 = 5X3). The interval and subinterval value may be 1 to 60 minutes. If both
values are the same, the demand interval is considered the fixed interval. A fixed interval period
should be evenly divided by the subinterval value in case of a sliding interval.
