Data Storage
• 60 minute
• 30 minute (default for standard load profile data)
• 15 minute
• 10 minute (default for voltage 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).
Data Storage
The SGM1430-B meter's data storage includes load profile, voltage profile,
time-of-use, and block tariff metering.
Load Profile
By default, the SGM1430-B meter can store a minimum of four channels of load
profile demand data, at an interval of 30 minutes, for a period of 24 months.
The number of channels is reconfigurable. For example, the meter memory can
store ten channels of load profile energy data, at an interval of 30 minutes, but
only for a maximum period of 210 days (7 months).
Voltage Profile
By default, the SGM1430-B meters can store a minimum of four channels of load
profile demand data, at an interval of thirty 30 minutes, for a period of 3 months.
Memory Overwrite
The meter will overwrite the oldest load profile data first in the event that all
memory allocated to the profiles is consumed. It is the responsibility of the energy
supplier to ensure that all data is retrieved punctually.
Power Outages
Flags set in the status data of profile interval periods around power outages
determine where power outages have occurred. The energy supplier will need to
reconstruct the data based on these flags and time stamp data. No holes are left in
the data where these outages have occurred.
