Table 13-42. Instantaneous 50T Element Accuracy
Sensing Type Pickup Accuracy - Phase and Neutral
A or B (1 ampere nominal systems)
±
2% of setting or
±
10 milliamperes
D, E, or F (5 ampere nominal systems)
±
2% of setting or
±
50 milliamperes
Step 5. After pickup occurs, slowly ramp the current down until both OUT1, OUT2, and OUT3 open.
Verify that dropout occurred as specified (95%
±
2%).
Step 6. Repeat Steps 3, 4, and 5 for all values in Table 13-42. 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 3 through 6 for phases B and C of the relay unless each phase was
tested in step 4. If so, skip this step and proceed to Step 8.
Step 8. (Optional) Repeat steps 1 through 7 for the 150T and 250T elements. Use Table 13-43 or 13-
44 as a reference for substituting the commands used in Step 1.
Table 13-43. Instantaneous Overcurrent 150T Element Test Logic
Replace These Commands With These Commands For 150T Element Tests
SL-50T=1,0 SL-150T=1,0
SL-VO1=50TPT SL-VO1=150TPT
SL-VO2=50TNT SL-VO2=150TNT
SL-VO3=50TQT SL-VO3=150TQT
SG-TARG=50T SG-TARG=150T
SG-TRIGGER=50TPT+50TNT+50TQT,
50TQPU,0 SG-TRIGGER=150TQT,

Table 13-44. Instantaneous Overcurrent 250T Element Test Logic
Replace These Commands With These Commands For 250T Element Tests
SL-50T=1,0 SL-250T=1,0
SL-VO1=50TPT SL-VO1=250TPT
SL-VO2=50TNT SL-VO2=250TNT
SL-VO3=50TQT SL-VO3=250TQT

SG-TRIGGER=50TPT+50TNT+50TQT,
50TQPU,0 SG-TRIGGER=250TQT,
250TQTPU,0
Step 9. (Optional) Repeat steps 1 through 8 for the 50T, 150T, and 250T elements in setting groups 1,
2, and 3. Use the following information as a guide to program the 50T/150T/250T 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 -50TP, S 0 -50TN, and S 0 -50TQ commands in Table 13-41 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\50T\50T, 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.
