Step 2: Use BESTCOMSPlus to configure the BESTlogicPlus Programmable Logic shown in Figure

311.

• Blocking is disabled.

• OUT1 closes for 40Q Trip.

• OUT2 closes for 40Q Pickup.

• Fault recording is enabled.

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 228 to the BE1-11g.

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 BE1-11g 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 228. Record the

results.

Step 8: (Optional.) Repeat steps 1 through 7 for settings group 1, 2, and 3.

Step 1: 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 229 to the BE1-11g for settings

group 0.
