Configuring sag/swell using the display

You can use the display to configure sag/swell data as a trigger to capture waveforms.
  1. Navigate to Maint > Setup .
  2. Enter the setup passcode (default is “0”), then press OK.
  3. Navigate to Dist.
  4. Move the cursor to point to the parameter you want to modify, then press Edit.
  5. Modify the parameters as required, then press OK.
  6. Press the up arrow to exit. Press Yes to save your changes.

    Sag and swell setup parameters available using the display




    Sag Limit

    1 – 99

    Set the sag limit values in %
    NOTE: Sag limit + hysteresis must be ≤100
    Swell Limit

    101 – 199

    Set the swell limit values in %
    NOTE: Swell limit - hysteresis must be ≥100

    1 – 100

    Set the hysteresis value

    The hysteresis is the difference in magnitude between the start and end thresholds for sag/swell. For example, a hysteresis of 5% means that a sag with a threshold of 90% needs to reach 95% before the sag is over and a swell with a limit of 110% needs to reach 105% before the swell is over.

    PQ Voltage Level

    100 – 1000000

    Set the system nominal voltage level
    NOTE: The user must configure the nominal voltage L-L for 3PH3W or L-N for other power system configurations.
