Voltage Quality Measurements
Threshold, the meter generates an event in the Power Event Log and also sends an
alert via the HAN.
Under Voltage Threshold
Upon detecting that the value calculated for phase [n] is below the Phase [n]
Average RMS Under Voltage Threshold, the meter will increment the Phase [n]
Average RMS Under Voltage Counter, update the Power Event Log, and send an
alert via the HAN.
Upon detecting that the value calculated for phase [n] is above the Phase [n]
Average RMS Over Voltage Threshold and the value calculated in the prior
configurable period was above the Phase [n] Average RMS Under Voltage
Threshold, the meter generates an event in the Power Event Log and also sends an
alert via the HAN.
RMS Extreme Over Voltage
If the RMS voltage for Phase [n] rises above the RMS Extreme Over Voltage
Threshold for a duration longer than specified in the RMS Extreme Over Voltage
Measurement Period, the meter will generate a corresponding entry in the Power
Event Log and send an alert to the HAN interface.
If the RMS voltage returns to a value below the RMS Extreme Over Voltage
Threshold longer than the configured measurement period, the meter will generate
a corresponding entry in the Power Event Log and send an alert to the HAN
interface.
RMS extreme Under Voltage
If the RMS voltage for Phase [n] falls below the RMS Extreme Under Voltage
Threshold for a duration longer than specified in the RMS Extreme Under Voltage
Measurement Period, the meter will generate a corresponding log entry and send
an alert to the HAN interface.
When the RMS voltage returns to a value above the RMS Extreme Under Voltage
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.
RMS Voltage Sag
If the RMS voltage for Phase [n] falls below the RMS Voltage Sag Threshold for
a duration longer than specified in the RMS Voltage Sag Measurement Period, the
meter will generate a corresponding entry in the Power Event Log and send an
alert to the HAN Interface.
When the RMS voltage returns to a value above the RMS Voltage Sag 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.
RMS Voltage Swell
If the RMS voltage for Phase [n] rises above the RMS Voltage Swell Threshold
for a duration longer than specified in the RMS Voltage Swell Measurement
