Configuring sag/swell alarms using ION Setup

You can use ION Setup to configure the sag/swell alarm settings.
  1. Start ION Setup.
  2. Open the Setup Assistant for your meter.
  3. Navigate to Alarming > Sag/Swell.
  4. Select the parameter you want to configure and click Edit.

    The setup dialog box for that parameter appears.

  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.
