Step 4:
Slowly ramp up current on the phase A input until OUT1, OUT2, and OUT3 close. Verify that
pickup occurred within the specified accuracy of the relay as listed in Table 13-52.
Table 13-52. Time Overcurrent 51 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 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 13-46. Optionally, reconnect the current
source to B-phase (A5*, A6) and C-phase (A7*, A8) 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 151/251/351/451 elements. Use Table 13-53 or
13-54 as a reference for substituting the commands used in Step 1.

With These Commands For 151 Element Tests
SL-51=1,0 SL-151=1,0

Table 13-54. Time Overcurrent 251/351/451 Element Test Logic

With These Commands For x51 Element Tests
(where x=2,3,4)
SL-51=1,0 SL-x51=1,0
SL-VO1=51PT SL-VO1=x51PT
SL-VO2=51NT SL-VO2=x51NT

51NPU,+51QPU,0
SG-TRIGGER=x51PT+x51NT+x51QT,
x51QTPU,0
Step 9:
(Optional.) Repeat Steps 1 through 8 for the 51, 151, 251, 351, and 451 elements in Setting
Groups 1, 2 and 3. Use the following information as a guide to program the 1/151/251/351/451
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 13-45 with a 1, 2, or 3
for Setting Groups 1, 2, or 3. With the HMI, 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.
