5. Configure the parameters as required.
The values you need to set vary depending on the type of sag/swell alarm you
are configuring.
Voltage sag/swell setup parameters
Parameter
Value/Range
Description
Enable/Disable
Enabled or Disabled
Specifies if sag/swell recording and alarming is enabled.
Nominal
1 to 999,999
Specifies the nominal voltage value used for sag/swell detection.
Swell Limit
Percentage of nominal
Specifies the swell limit expressed as a percentage of the nominal voltage.
Sag Limit
Percentage of nominal
Specifies the sag limit expressed as a percentage of the nominal voltage.
Hysteresis
Percentage – see
description
Specifies the difference in magnitude between the sag or swell limit and the
threshold for the power quality event to be considered over.
For example, if the meter has the sag limit set to 90% of nominal and the
hysteresis is set to 2%, this means that in a sag event, the voltage needs to return
to 92% of nominal for the sag event to be considered over
Alarm priority
See description
Select the alarm priority you want to associate with Sag/Swell alarms.
To stop an alarm from being displayed without affecting other meter features, set
the alarm priority to Info Only.
Current sag/swell setup parameters
Parameter
Value/Range
Description
Enable/Disable
Enabled or Disabled
Specifies if sag/swell recording and alarming is enabled.
Nominal
1 to 999,999
Specifies the nominal current value used for current sag or current swell detection.
Pickup
Percentage of nominal
Specifies the percentage the current must deviate from the nominal current in
order to be classified as a sag or a swell.
Dropout
Percentage of nominal
Specifies the percentage of nominal the current must recover to in order to signal
the end of the sag or the swell.
Hysteresis
N/A
Displays the difference in magnitude between the sag or swell Pickup and
Dropout values.
To change the hysteresis, change the Pickup or Dropout values.
Alarm priority
See description
Select the alarm priority you want to associate with Sag/Swell alarms.
To stop an alarm from being displayed without affecting other meter features, set
the alarm priority to Info Only.
