UNCTIONALITY
The SGM1430-B 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 SGM1430-B 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 SGM1430-B 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).
Number Instantaneous Measurement
1 Total Active Power – kW
2 Import Active Power – kW
3 Export Active Power – kW
4 Total Import Reactive Power (Q1+Q2) – kVAr
5 Total Export Reactive Power (Q3+Q4) – kVAr
6 Reactive Power in Quadrant 1 (Q1) – kVAr
7 Reactive Power in Quadrant 2 (Q2) – kVAr
8 Reactive Power in Quadrant 3 (Q3) – kVAr
9 Reactive Power in Quadrant 4 (Q4) – kVAr
10 RMS Voltage
11 RMS Current
12 Frequency
