Voltage Swells
Verify the Power Quality instrument connected to the simulator has a programmed
swell limit of no more that 10% of the MPQSIM voltage output that it is connected.
NOTE: If you wish to record RMS values as well it may be best to set the RMS
storage interval to 3 seconds, so you do not need to wait a long period to
acquire saved RMS intervals.
1. Verify the controls are set to their initial settings.
2. Start the unit recording.
3. Allow the unit to record for several seconds.
4. Note there are no recorded Swell events.
5. Set one of the voltage phase Amplitude selector switches to 115%.
6. Allow the unit to record for several seconds.
7. Set the voltage phase Amplitude selector switch back to 100%.
8. Allow the unit to record for several seconds.
9. Note the unit now displays a Swell event.
10. Stop the recording.
11. The Swell event can now be viewed on the unit.
Voltage Transients
1. Verify the Power Quality instrument connected to the simulator has a
programmed with sag and swell limit of no more that 10% of the MPQSIM
voltage output that it is connected.
2. Verify the Power Quality instrument connected to the simulator has a
programmed with transient limit of 140.00 for a 115VAC voltage connection or a
transient limit of 280.00 for a 230VAC voltage connection.
NOTE: If you wish to record RMS values as well it may be best to set the RMS
storage interval to 3 seconds, so you do not need to wait a long period to
acquire saved RMS intervals.
3. Verify the controls are set to their initial settings.
