Verifying The Signals And Settings; Completing The Test; Delta Supervision Of Real Input Delspvc - Hitachi RED670 Commissioning Manual

1MRK 505 378-UEN Rev. K
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:
•
•
•
•
•
•
2. Set the constant current input of IL1 = 1A at 0° and IL2 = 1A at 120° and IL3 at -120°
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.

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.

Delta supervision of real input DELSPVC

Prepare the IED for verification of settings outlined in Section
11.9.6.1 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.
