5.3.2 Distance scheme test (if validated in S1 & PSL)
5.3.2.1 Control
•
The type of distance scheme enable in S1
•
The DDB cells assigned for distance scheme
•
Ref to the description feature in P44x /EN AP item 2.4 & 2.5:
⇒
Settings in S1
⇒
DDB cells
⇒
Internal logic in A2.10 & A3.2
REMINDER: General equation to the tripping in distance protection since
A2.9/A3.1 – From A2.10/A3.2 could be found in the Chap EN AP –
item 2.5
NOTE : Before tests, control the input presence /Output in PSL (See chapter
AP section 6.2 & 6.3) linked to the selected teleaction scheme (DDB :
DistCR/Dist CS/).Control as well the I/O condition change (on LCD in
FAV in "system ")
Input :(PSL by default "P&C ") Output : (PSL by default "P&C ")
WARNING : TAKE CARE ABOUT THE CHANGEMENT OF GROUP BY OPTOS
– IF SELECTED IN S1 (OPTO 1 & 2 IN THAT CASE SWITCHING GROUPS
BY
OPTOS)
– IF USED FOR SWITCHING GROUP (OPTO 1 & 2 MUST BE ABSENT
FROM THE PSL)

Signal Send (Dist + DEF)
1. From MiCOM S1, select a one of the mode in the table 5.6 in P44x /EN AP (last
column).
2. Implement the indicated default in the panel first column , The carrier signal input
being activated (with TAC).
3. Check the tripping contact have been energised at the issue of the indicated time
delay indicated in the same column (With TAC).
4. Repeat step 2 and 3 but without teleaction input and by checking the indicated time
delay in the panel’s 2nd column (Without TAC).
Repeat step 2 and 4 for the others zones defaults by checking, whatever the teleaction input
condition, the associated time delays to every zones are not modified (according to the 4th
column equations)
NOTE : – TAC can be simulated by inverting the opto.
– TAC transmissions can also be checked by generating
defaults according to the 3rd column.
– To make easy the relay I/O control condition, the LEDs
affectation in PSL can be modified. Another possibility is in S1 –
See Testing tools (monitor bit control).
