Viewing Voltage Tolerance

View Voltage Tolerance to investigate the potential impact of a voltage disturbance on equipment.

NOTE: Voltage Tolerance analysis is only available for alarm instances and incidents, not for alarm status. Also, the data associated with the alarm or incident must include voltage disturbance measurements.

To view Voltage Tolerance:

In the alarm viewer, open an existing alarm history or incident history view from the view library or add a new View.
TIP: Add a Voltage Tolerance filter to your view to identify alarms and incidents that fall into a certain area of the ITIC/CBEMA curve. You can add this filter in View Settings > Categories > Power Quality. See Voltage Tolerance for more information.
NOTE: The Voltage Tolerance filter settings only apply to the following Power Quality alarm or incident types: Interruption, Under Voltage, Over Voltage, Sag, Swell, Unclassified Disturbance, Transient.
Find the alarm instance or Incident for which you want to view Voltage Tolerance, and click Open Details to open the details window.
In the details window, select Tolerance Chart in the display selector on left side of the window.

For an alarm instance, a single voltage disturbance is displayed in the chart. For incidents, all available voltage disturbances for the alarms that are part of the Incident are displayed.
