Step 3: Use BESTCOMSPlus to open the Protection, Power, Loss of Excitation - Reverse Var Based
(40Q) screen and send the first row of test settings in Table 170 to the BE1-11m.

Pickup Setting Time Delay
500 var 50 ms
1,000 var 50 ms
2,000 var 50 ms
Step 4: Connect and apply a 100 Vac, three-phase voltage source at nominal frequency to terminals
C13 (A-phase), C14 (B-phase), C15 (C-phase), and C16 (Neutral). Connect a variable ac
current source to terminals D1 (A-phase polarity) and D2 (A-phase non-polarity).
Step 5: Set A-phase current to lag the voltage by 90 degrees and slowly increase the current from
0 amps until OUT2 closes and record the pickup. Verify the 40Q target on the front-panel
display. Decrease the A-phase current until OUT2 opens and record the dropout.
Step 6: With the BE1-11m picked up (OUT2 closed), change the angle of the applied current to
90 degrees I lag E and verify that OUT2 opens. This verifies that the 40Q function is operating
on leading var.
Step 7: Repeat steps 5 and 6 for the 1,000 var and 2,000 var pickup settings in Table 170. Record the
results.
Step 8: (Optional.) Repeat steps 1 through 7 for settings group 1, 2, and 3.
