Energy management system with WAGES analysis capabilities
Incremental energy allows you to define a start time, end time, and the time interval
(increments) for incremental energy accumulation.
At the end of each interval, the energy accumulated during that period is stored. By
default, the meter only records the previous interval's incremental energy and the
instantaneous energy accumulations in the active interval.
The first interval of incremental energy accumulation begins at the specified start time.
Incremental energy ends at the specified end time, which may result in a truncated
interval if the interval duration does not divide evenly into the overall incremental
energy duration (for example, an interval duration of three hours with an overall
duration of five hours truncates the last interval duration to two hours). The latest value
for the specified end time is midnight (24:00).
Your start time must be before the end time and after midnight, and the period over
which incremental energy is accumulated cannot include midnight. This is because
your meter's start and end times are defined relative to midnight.
Start: 6 am, End:
Incremental energy accumulates from 6 am to midnight in intervals of 3 hours.
12 am, interval: 3
hrs
Start: 6 am, End: 2
Incremental energy will not function. End time must be after start time and before or
am, interval: 3 hrs
equal to midnight.
Incremental energy helps provide information for analyzing energy and power usage
against present or future utility rates, and is useful for comparing different time-of-use
rate structures.
When configuring incremental energy, shorter incremental energy periods provide
more granular data which can make the data easier to use for comparison purposes.
