The Show | Relay Test Values command in the OC Curves Window lets you compute one or more test values for a relay or recloser that is being displayed. The test values (in the form of X times pickup and Y seconds delay) are for the most recent relay or recloser settings. The test values are unaffected by any of the shifting factors.
TO OBTAIN THE TEST VALUES:
1. Select the Show | Relay Test Values command.
A dialog box will appear listing the relays and recloser being displayed in the Curves Window.
2. Select one of the devices and press OK.
For a relay, the program will display on the TTY window a table of time delays versus test currents. If the time unit for the OC Curves Window is in cycles (50 or 60 Hz), the table will also list the time delays in cycles.
For a recloser, the program will display a table of time delay versus time currents at 2, 5, 10 and 15 times the minimum trip current.
3. Select Menu | Close Window to close the TTY Window.
4. Press OK to close the Show Relay Test Value dialog box.
