Data Storage
Data Storage
The SGM1400-B Series meter’s data storage includes load profile,
instrumentation profile, time-of-use, and block tariff metering.
Load Profile
By default, the SGM1400-B Series 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).
Instrumentation Profile
By default, the SGM1400-B Series 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.
Time-of-Use (TOU)
The meters support multiple TOU registers. The minimum quantity of TOU
registers are as follows:
• 48 rates (for Import Active Energy only)
• 6 day types per week
• 16 day profiles
• 5 week profiles
• 4 season profiles
• 50 special day profiles
Additionally, the SGM1422-B dual element meter supports the following TOU
registers intended for second element tariffs:
• 4 rates (for Import Active Energy only)
• 6 day types per week
