TOU Register Data
Contains all registers included in a Rate X register set for each of the rates you
have defined. These are the data necessary to produce a bill for the consumer.
Cumulative Demand
The sum of the peak demand readings after each demand reset during the
same billing period. At each demand reset, the meter adds the peak demand
from the most recent billing period to the previously accumulated total of all
peak demands.
Day Type
A day (24 hours) that has a specific rate assigned for each season through the
Rate-Schedule table. Day Types are Monday, Tuesday, Wednesday, Thursday,
Friday, Saturday, Sunday, Alternate 1, Alternate 2, and Alternate 3. These
represent the typical days of the week and three alternate days for holidays or
special occasions.
Five Maximum
MW/MVAR/MVA
“Total” Demands
The five maximum megawatt/VAR/volt-ampere demand values recorded since
the last demand reset. The values are nonrated and are listed from highest to
lowest. The meter uses the Total Calculation setting to calculate these registers
and includes timestamps for each of the five maximum demands. The
maximum demand includes the coincident power factor.
MWH/MVAH Total
At/Since Demand
Reset
Each demand reset resets to zero the values the meter has collected since the
previous demand reset. See Figure 5.13.
