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.
11.11.7.3 Sudden change in current variation SCCVPTOC
GUID-5494DF56-449D-49BE-B75D-9C667E890E16 v1
Prepare the IED for verification of settings as outlined in section
"Requirements"
and section "Preparing for test" in this chapter.
1.
Set Operation to On.
2. Connect the test set for three-phase current injection to the appropriate IED
terminals.
3. Inject symmetrical phase currents equal to half the rated current.
4. Increase the injected current in phase L1 slowly by more than the set I>. No
signal shall be activated.
5. Decrease the injected current in phase L1 to half the rated current.
6. Increase the injected current in phase L1 in a step by more than the set I>.
Start and trip signal shall be activated.
11.11.7.4 Carrier receive logic LCCRPTRC
GUID-16B24935-A9F4-427C-9B8D-71B25DE000E2 v1
Prepare the IED for verification of settings as outlined in section
"Requirements"
and section "Preparing for test" in this chapter.
1.
Set Operation to On.
2. Select OpMode according to the application: If two carrier channels are used
and high security shall be used set OpMode = 2 Out Of 2, otherwise 1 Out Of
2.
3. Connect switchable binary signal/s CR1 and CR2 to the binary input/s to be
used for the carrier receive (CR) signal/s.
4. Connect switchable binary signal/s to the binary input to be used for the local
check signal. If three pole trip is used only one LOCTR is used. If single pole
trip is used in addition the phase selective signals LOCTRL1, LOCTRL2and
LOCTRL3 are connected.
5. Connect switchable binary signal/s to the binary input to be used for the
communication supervision signal/s CHERR1 and CHERR2.
If OpMode = 2 Out Of 2:
6. Activate input and check output signals according to table
39 and 40.
