Configuring sag/swell using ION Setup
- Start ION Setup and connect to your meter.
- Open the Voltage Sag/Swell screen in the Power Quality folder.
- Click Edit to configure the Setup parameters as required.
- Click Send to save your changes
to the meter.
Voltage sag/swell parameters available using the ION Setup
Parameter Values Description PQ Voltage Level
100 – 1000000
Set the voltage level to the required valueNOTE: The user must configure the nominal voltage L-L for 3PH3W or L-N for other power system configurations. Sag Limit %
1 – 99
Set the sag limit valuesNOTE: Sag limit + hysteresis must be ≤100 Swell Limit %
101 – 199
Set the swell limit valuesNOTE: Swell limit - hysteresis must be ≥100 Hysterisis %
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.
