Components and Controls
• A text component displays the title at the top of the Impedance View shown
in Figure 10.65: Opening Impedance Screen. The title is compiled from
items in the Title Options dialog box. Default title is the file name and trig-
ger event.
• The basic channel names are displayed below the title.
• The 4 zoom is controlled using the sliding control on the right side of the
window. The R-X plot aspect ratio is maintained under all zooming tools.
The graph zoom control offers a 10x zoom factor between minimum and
maximum amplitude of the data (R and X coordinates).
• The Time Window control provides a means to select the range of data for
better presentation of R-X values. For example, if the voltage and current
channels are recorded from 0.0 to 0.2 seconds with 1000 data points, using
this control, you can choose to view only 0.1 second data (500 points).
• Time window width and position control can be used for the precise data
analysis.
• Control the X and O markers.
Create Impedance View with an TESLA LITE Record
1. Launch RecordGraph with an TESLA LITE high speed (fault) record and
expand the channels in the tree view.
2. Create an Impedance View using View>Add… or use the tool bar option.
3. Select line voltages A, B and C, and corresponding line currents A, B and C
from the tree view. Impedance (R and X) corresponding to Zab, Zbc and
Zca phase-phase are calculated internally and displayed.
