demand quantities for load profile (LP) and average instrumentation quantities for
instrumentation profile (IP).
Load Profile
Load profile is traditionally configured to record a number of demand quantities
(channels) at discrete time intervals (periods).
Four load profile channels are supported and are defaulted to the following:
• Import Active Energy
• Export Active Energy
• Import Reactive Energy
• Export Reactive Energy
These channels can be easily expanded (or contracted); however, the modification
will be detrimental to the overall storage capacity.
When reconfiguring the channels, the energy supplier must retrieve all load profile
data prior to the change, as changes will initiate a reset of the profiles.
Voltage Profile Log
The SGM1400-B Series meter offers profiling of the average RMS voltage.
By default, the only channel that is configured is for RMS Voltage (Default
Channel 1: Voltage Profile Data Log).
Interval Times
The following time intervals, as a minimum, are supported for both load and
instrumentation profiles and are independent of each other:
• 60 minute
• 30 minute (default for standard load profile data)
• 15 minute
• 10 minute (default for instrumentation profile data)
• 5 minute
• 1 minute
Interval Time Changes
In the event of a change of profile interval time, the energy supplier must retrieve
all load profile data prior to the change, as changes will initiate a reset of the
profiles.
This eliminates the possibility of the headend system reading across different
profile periods, where the system assumes homogeneous buffer entries (all entries
have the same size and structure).
