Chapter 5 • Metrology Functionality
Period, the meter will generate a corresponding entry and send an alert to the HAN
interface.
When the RMS voltage returns to a value below the RMS Voltage Swell
Threshold for a duration longer than the configured measurement period, the
meter will generate a corresponding log entry and send an alert to the HAN
interface.
Supply Outage Reporting
The meter may be configured to record the date and UTC when the supply via
Phase [n] is interrupted and when it is restored. Once configured, the meter will
generate a corresponding entry in the Power Event Log. Once the supply has been
restored, the meter will send an alert to the HAN interface that includes the date
and UTC of both the interruption and restoration.
Following restoration of the supply via Phase [n], if the time difference between
the supply being interrupted and then restored is greater than or equal to three
minutes, an alert to that effect will be generated and sent via the HAN Interface
containing details of the UTC date and time of interruption and restoration.
Profiles
The SGM1430-B meter supports non-volatile recording of two profiles of a
number of quantities (channels) at discrete time intervals (periods).
These two profiles are:load profile (profile 1) and voltage profile (profile 2).
These profiles are usually defined by the quantity type captured in each profile:
demand quantities for load profile (LP) and average voltage quantities for voltage
profile.
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.
Interval Times
The following time intervals, as a minimum, are supported for both load and
voltage profiles and are independent of each other:
