This page describes how to analyze individual events and transients with the Event Browser of GridVis software.
When you click on an element (event or transient) in the List view, the Analyze window opens. You can also open the Analyze window from the CBEMA chart. Note that only certain voltage events are listed in the CBEMA chart.
The Analyze window consists of the following three areas:
Fig. 1: Analyzing event
Select the data source for the measure value chart and add more measure values and phases to the chart.
Fig. 2: Data tab
Contains a list of all events and transients recorded by the same device (History of Device). You use History to open a CBEMA chart for the corresponding device.
By activating the checkbox, you open a CBEMA chart for the voltage events of the selected device. You use the input field to adjust the nominal voltage that serves as the reference point for the chart.
If filters are active, they are listed in the header of the History of Device and can be removed here or temporarily deactivated by clicking on them.
By clicking on an element from the list, it is selected and displayed in the header (Fig.1 1) and in the measure value or CBEMA chart.
Some measurement devices also record three-phase events in addition to the single-phase events. If an event occurs in all three phases, these three events are combined into a three-phase event.

You use this tab to adjust the representation of the measure value chart.
