13.9.5.2 Completing the test
Continue to test another function or end the test by changing the TestMode setting to Off. Restore
connections and settings to their original values, if they were changed for testing purposes.
13.9.6 Delta supervision of real input DELSPVC
Prepare the IED for verification of settings outlined in Section
13.9.6.1 Verifying the signals and settings
Make sure that the function is connected to any of the available real derived outputs, for example the
P output signal of the CMMXU function.
1. Set the following parameters:
•
•
•
•
•
2. Set a constant voltage input of UL1 = 63.5 V at 0° and UL2 = 63.5 V at 180° secondary and a
current signal at IL1 = 1A at 0° and IL2 = 1A at 180°.
3. Ensure that the P output of CMMXU function has exceeded 10 MW and remains stable.
4. Change the current signal at IL1= 2A at 0° and IL2= 2A at 180°. Both START and STARTRISE
signals should be active for 100 ms.
5. Change the current signal at IL1= 1A at 0° and IL2= 1A at 180°. Both START and STARTLOW
signals should be active for 100 ms.
13.9.6.2 Completing the test
