11.9.4.2 Completing the test
Continue to test another function or end the test by changing the TestMode setting to Disabled. Restore
connections and settings to their original values, if they were changed for testing purposes.
11.9.5 Current based delta supervision DELISPVC(7I)
Prepare the IED for verification of settings outlined in Section
11.9.5.1 Verifying the signals and settings
Make sure that the function is connected to SMAI function with I3P signal.
Delta supervision function has four different modes of operation. Proceed as follows to test the function in
a particular mode.
1. Set the following parameters:
