Power Quality Measurements
Frequency of Supply
The SGM1430-B meter supports measurement of the frequency of the main
supply.
Cumulative Registers
The SGM1430-B meter supports the following cumulative observables for each
measuring element as well as total. The data is internally stored in milliunits.
Power Quality Measurements
The SGM1430-B meters are capable of supporting power quality events and
functionality including over/under voltage, sags or swells, over/under frequency,
over current, and power factor. The meter may be configured to perform the
following when the threshold parameters are met for over/under voltage, sags or
swells, over/under frequency, and over current events:
• Update the event log
• Open the load switch
• Send an alert to the headend
For power factor events, the meter may be configured to update the event log or
send an alert to the headend when the threshold parameters are met.
The configuration of these power quality events are described in more detail in the
following sections.
Over Frequency and Under Frequency
The SGM1430-B meters have configurable over frequency and under frequency
thresholds and durations. The thresholds can be configured as follows:
13 Power Factor
14 Phase Angle
Number Instantaneous Measurement
Number Cumulative Register
1 Total Active Energy – kWh
2 Import Active Energy – kWh
3 Export Active Energy – kWh
4 Total Reactive Energy – kVArh
5 Total Import Reactive Energy (Q1+Q2) – kVArh
6 Total Export Reactive Energy (Q3+Q4) – kVArh
7 Reactive Energy in Quadrant 1 (Q1) – kVArh
8 Reactive Energy in Quadrant 2 (Q2) – kVArh
9 Reactive Energy in Quadrant 3 (Q3) – kVArh
10 Reactive Energy in Quadrant 4 (Q4) – kVArh
