Step 2: Use BESTCOMSPlus to configure the BESTlogicPlus programmable logic shown in Figure 266.

Blocking is disabled.

OUT1 closes for 55 Trip.

OUT2 closes for 55 Pickup.

Fault recording is enabled.

Step 3: Use BESTCOMSPlus to open the Protection, Power, Power Factor (55) screen and verify the

first row of test settings in Table 173 to the BE1-11m.

Step 4: Prepare to monitor the 55 function operation. Operation can be verified by monitoring OUT1

(see Figure 266).

Step 5: Connect and apply 5 A

∠0° to terminals D1 (A-phase polarity) and D2 (A-phase non-polarity)

and a three-phase 69.28 V phase-neutral voltage source to terminals C13 (A-phase), C14 (B-
phase), C15 (C-phase), and C16 (Neutral).

Step 6: Rotate the IA angle in the leading direction until a pickup occurs. This should happen at

∠IA =

∠VA + cos

-1

(0.5) = +60

° ±0.66° (0.49 – 0.51 PF leading). Decrease the IA angle until OUT1

opens and record the reset. Reset the target.

Step 7: Rotate the IA angle in the lagging direction until a pickup occurs. This should happen at

∠IA =

∠VA – cos

-1

(0.5) =

–60° ±0.66° (0.49 – 0.51 PF lagging). Increase the IA angle until OUT1 opens

and record the reset. Reset the target.

Step 8: Verify the pickup accuracy and reset for settings as listed in Table 173. Record the results.

Pickup accuracy is ±0.01 PF or equivalently

Step 9: (Optional.) Repeat steps 1 through 8 for the B-phase and C-phase current inputs taking into

consideration the different current angles. Note: Be sure to enable proper target for each phase
being tested.

Step 10: (Optional.) Repeat steps 1 through 9 for settings group 1, 2, and 3.

Timing Verification

Step 1: Use BESTCOMSPlus to open the Protection, Power, Power Factor (55) screen and send the

first row of test settings in Table 2 for settings group 0.

Step 2: Prepare to monitor the 55 timings. Timing accuracy is verified by measuring the elapsed time

between a sensing voltage change and OUT1 closing.
