Testing functionality by secondary injection
10.8.4 Current based delta supervision DELISPVC
Prepare the IED for verification of settings outlined in Section
10.8.4.1 Verifying the signals and settings
Make sure that the function is connected to SMAI function with I2P 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:
•
•
•
•
•
•
2. Set the constant current input of IL1 = 1A at 0° and IL2 = 1A at 180° secondary at rated
frequency.
3. Based on the mode of operation, carry out the following changes on input condition of Step
detect start condition.
Each mode is given for increase and decrease operation. (3-a and 3-b)
Step No.
3-a
3-b

3-b
4. Repeat Step
10.8.4.2 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.
10.8.5 Delta supervision of real input DELSPVC
Prepare the IED for verification of settings outlined in Section
10.8.5.1 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.
