When you select the Relay data & impedance options button, a dialog box ap-
pears. The parameter required, such as k0 factor, the line sequence impedance
values, the system voltage data and the other required information is initialized
through this dialog box initialization. All these values are read from the set-
tings file opened through the impedance option dialog box.
In the Relay data and impedance options dialog box check the Zone 1 to Zone
4 boxes and select the Apply button. All the four zone characteristics are super-

Relay data and impedance options
L-PRO settings file Radio button to select relay characteristics from the current
record. If an L-PRO record is selected, this button is enabled.
Current record If a TESLA LITE or COMTRADE record is selected, this button
is enabled.
File Displays the settings file (full path name) from which the relay
data is extracted to plot the impedance characteristics.
Browse Gives an option to select the settings file from any other location.
The file type filter reads or selects only *.lps file type, if L-PRO
setting file is selected.
Impedance Options Impedance configuration option includes a number of other
options, such as, Phase-Phase, Phase-Neutral, radio button.
Depending on this option and the type of channel, different
impedance options (check buttons) are enabled.
Configuration Zpos (positive sequence impedance 3 phase basis).
Zan, Zbn or Zcn.
Zab, Zbc, or Zca.
Other Impedance
Z-Line Displays the line angle (can be checked or unchecked).
Z-Load Displays the coordinate of the load impedance (can be checked
or unchecked).
Blinders Available only if the Phase-Phase option is chosen.
Directional Displays the directional characteristics.
Zones to display Phase-Ground or Phase-Phase.
Zone 1 to 4 Zone1-Zone4 displays the respective zones impedance charac-
teristics (can be checked or unchecked).
Apply Redraws the display with the currently selected options.
Launch Launches the setting file through the Offliner settings program.
Note that the L-PRO Offliner setting program should be installed
for this to work successfully.
Close Closes the dialog box.
