SHOW TIME-DISTANCE CURVE COMMAND

The Run | Show Time-Distance Curve command in the Time-Distance Window simulates faults and plots the time-distance curves for all the monitored relays.

No time-distance curves are visible when you first open the Time-Distance Window, or immediately after you have modified the diagram or parameters of the branches and relays.  You must execute this command to show the time-distance curves.

TO SHOW THE TIME-DISTANCE CURVES:

1.   Make sure there are one or more monitored relays on the diagram.

You can tell visually whether there are any monitored relays.  The interior of a relay group symbol is painted gray if it contains one.

2.    Change the fault type and the fault impedance, if needed, with the Misc | Options command.

3.    Press the button at the upper left corner of the window.

Note: This command cannot be executed if there are no monitored relays on the diagram.
