9328900990 Rev L BE1-951 Reporting and Alarm Functions 6-29
The RG-TARG (report general-targets) command is used to read and reset targets through the
communication ports.
RG-TARG Command
Purpose: Report general information (date, time and targets).
Syntax: RG-TARG=0
Comments: Entering RG-TARG returns the target information logged during the most recent trip
event.
Entering RG-TARG=0 clears the latched target data.
RG-TARG Command Example:
Example 1. Read the targets.

Distance to Fault
The BE1-951 calculates distance to fault each time a fault record is triggered. Distance to fault is
calculated and displayed based on the power line parameters entered using BESTCOMS, the HMI, or
with the SG-LINE command.
Table 6-16 provides the power line operating settings.
Table 6-16. Power Line Operating Settings
Setting Range Increment Unit of Measure Default
Positive-Sequence Magnitude (Z1) 0.05 to 200 0.05 Ohms 8
Positive-Sequence Impedance Angle (A1) 0 to 90 1 Degrees 80
Zero-Sequence Magnitude (Z0) 0.05 to 650 0.05 Ohms 24
Zero-Sequence Impedance Angle (A0) 0 to 90 1 Degrees 80
Length of Power Line (LL) 0.01 to 650 0.01 Units 100
The command (SG-LINE) describes the power line parameters for which distance is to be computed over.
The parameters should be entered in units per line length with line length being the actual length of the
power line. Line length is entered as unit-less quantities and, therefore, can be entered in kilometers or
miles. The distance results would, therefore, be in whatever units the line length represented.
Using BESTCOMS, power line parameters can be entered by selecting General Operation from the
S
creens pull-down menu. Then select the Power System tab (see Figure 6-16). Power line parameters
such as Positive-Sequence Impedance, Zero-Sequence Impedance, and Line Length can be entered in
the center pane under Power Line Parameters.
