Glossary
Average (Power): When applied to power values (Watts, VARs, VA),
the average is a calculated value that corresponds
to the thermal average over a specified time
interval.
The interval is specified by the user in the meter
profile. The interval is typically 15 minutes.
So, the Average Watts is the thermal average of
Watts over the previous 15-minute interval. The
thermal average rises to 90% of the actual value
in each time interval. For example, if a constant
100kW load is applied, the thermal average will
indicate 90kW after one time interval, 99kW after
two time intervals and 99.9kW after three time
intervals.
Bit: A unit of computer information equivalent to the
result of a choice between two alternatives (Yes/
No, On/Off, for example).
Or, the physical representation of a bit by an
electrical pulse whose presence or absence
indicates data.
Binary: Relating to a system of numbers having 2 as its
base (digits 0 and 1).
Block Window Avg
(Power): The Block (Fixed) Window Average is the average
power calculated over a user-set time interval,
typically 15 minutes. This calculated average
corresponds to the demand calculations
performed by most electric utilities in monitoring
user power demand. (See Rolling Window
Average.)
