Testing functionality by secondary injection
11.9.3.1 Completing the test
continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.
11.9.4 Voltage based delta supervision DELVSPVC
Prepare the IED for verification of settings outlined in Section
settings".
11.9.4.1 Verifying the signals and settings
Make sure that the function is connected to SMAI function with V3P signal.
Delta supervision function has 6 different modes of operation. Proceed as follows to test the
function in a particular mode.
1. Set the following parameters:
•
•
•
•
•
•
•
2. Set the constant voltage input of UL1 = 63.5V at 0° and UL2 = 63.5V at 120° and UL3 at 63.5
-120° secondary at rated frequency.
3. Based on the mode of operation, carry out the following changes on input condition of Step
to detect pickup condition.
Each mode is given for increase and decrease operation. (3-a and 3-b)
Step No.
