Step 6. Repeat Steps 3, 4, and 5 for all current and time dial settings listed (using the command S0-
51P, 51N, and 51Q or, if your relay is supplied with the HMI option, by navigating to screen
\PROT\SG0\51\51 to edit the 51P, 51N, and 51Q settings) and optionally, reconnect the
current source to B-phase (B3, B4) and C-phase (B5, B6) inputs to test the response of all
phases for each succeeding test.
Step 7. (Optional) Repeat Steps 2 through 6 for B and C phase elements unless each phase was
tested in previous steps. If so, skip this step and proceed to Step 8.
Step 8. (Optional) Repeat Steps 1 through 7 for the 151 and 251 elements respectively. Use Table 13-
51 or 13-52 as a reference for substituting the commands used in Step 1.
Step 9. (Optional) Repeat steps 1 through 8 for the 51, 151, and 251 elements in setting groups 1, 2,
and 3. Use the following information as a guide to program the 51/151/251 elements in higher
order setting groups.
In order to program the pickup of the elements in a higher order setting group, you would
replace the
0 in the S 0 -51P, S 0 -51N, and S 0 -51Q commands in Table 13-50 with a 1, 2, or 3
for setting groups 1, 2, or 3. Or, if your relay is supplied with the HMI option, you can program
each set of values by navigating to the appropriate setting group screen \PROT\SGn\51\51,
where n is equal to the setting group you desire. Refer to the CS/CO-GROUP command in
Section 4,
Protection and Control Functions for more information on changing the active setting
group.
To change from group 0 to group 1, execute the following commands.
CS-GROUP=1 select setting group 1
CO-GROUP=1 execute setting group 1
Using the basic information in Table 13-50, program the pickup of the elements for setting
group 1 and, optionally, proceed with the testing.
Breaker Failure
Purpose: To verify the operation of the breaker failure (BF) function.
Reference Commands: SL-BF, SP-BF
Step 1. Prepare the BF function block for testing by transmitting the commands in Table 13-53 to the
relay.
