UNCTIONALITY
The SGM1400-B Series meter supports an extensive feature set comprising
metrology related functions, support of tariffs, load profile, power quality data,
etc. The meter is similar to a complete energy meter (not just an electricity meter)
when coupled with appropriate ZigBee communication devices for metering gas.
Multipurpose Energy Metering
The SGM1400-B Series meter supports the storage and operation of multiple
energy types that are measured directly by the meter. Electrical observables are
measured directly by the meter.
Preferred measurements can be selected to be defined and stored independently
for each storage operation. These measurements include:
• demand calculations,
• time-of-use storage, and
• load profile storage.
Instantaneous Measurements
The SGM1400-B Series meter supports measurement of multiple electrical
parameters. The following instantaneous measurements are available for each
measuring element. These instantaneous data values are calculated and updated
every momentary interval (approximately one second).

2 Active Power Import – kW (Secondary)
3 Total Active Power Import – kW (Prim+Sec SGM1422-B)
4 Active Power Export – kW (Primary)
5 Active Power Export – kW (Secondary)
6 Total Active Power Export – kW (Prim+Sec SGM1422-B)
7 Reactive Import Power – kVAr (Primary)
