20. POWER QUALITY MONITORING

The meter calculates the Average RMS Voltage over a configurable period.

20.1. Voltage Monitoring

The Meter monitors the following Events:
•
Average RMS Over Voltage
•
RMS Extreme Over Voltage
•
RMS Voltage Swell
•
Average RMS Under Voltage
•
RMS Extreme Under Voltage
•
RMS Voltage Sag
All of these Events have the same features:
•
The event is created when the RMS Voltage is compared to a Configurable Threshold, over a Configurable
Period (if set to zero then the monitoring will not happen), providing that during the previous period the meter did
not record an event i.e., the event is raised for the first period following a period where an event was not
detected. If an Event is created the meter will:
-
-
•
When the average returns inside the threshold the meter will:
-
-
In addition the Average RMS Over and Under Voltage has the following meter function:
-
-

20.2. Supply Outage Reporting

The meter records with a UTC Date and Time Stamp:
•
When Power was Interrupted
•
When Power was Restored
This will generate an Event in the Power Event Log and on restoration an Event will be sent via its HAN

20.3. Long Power Fail

If the time between the Power Fail and the Power Restoration is equal to or greater than 3mins, then this will be logged as
a long Power Fail Event (with UTC Time & Date Stamp) in the Power Event Log.
