Step 4: With the BE1-11g picked up (OUT2 closed), change the angle of the applied current to lag the
voltage by 180 degrees and verify that OUT2 opens. This verifies that the 32-1 function is
operating in the forward trip direction and not in the reverse direction.
Step 5: Repeat steps 1 through 4 for the 250 W and 50 W pickup settings in Table 225. Record the
results.
Step 6: (Optional.) Repeat steps 1 through 5 for B-phase and C-phase currents. (Consult the Power
(32) Protection chapter for operating details.)
Step 7: (Optional.) Repeat steps 1 through 6 using 32-2 in place of 32-1.
Step 8: (Optional.) Repeat steps 1 through 7 for settings group 1, 2, and 3.
Step 9: (Optional.) Repeat steps 1 through 8 with CT2 as the bus CT selection for protection systems
equipped with two sets of CTs. In step 2 replace D1 with F1, D2 with F2, etc.
Reverse Tripping Direction (Underpower)
Step 1: Using Table 226 as a guide, send the 32-1 settings to the BE1-11g. Prior to each test, reset the
BE1-11g targets from the previous test.

Step 2: 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 3: Apply 4 amps A-phase current to lag the voltage by 180 degrees noting that OUT2 drops out.
Slowly decrease the current until OUT2 closes (1/3 of the three-phase setting) and record the
pickup. Verify that there is a 32-1-A-Under target on the front-panel display. Increase A-phase
current until OUT2 opens and record the reset. Pickup will occur within ±3% of the 32-1 pickup
setting (500 watts = 5 amps, 100 volts, 180 degrees I lag E)/3.
Step 4: With the BE1-11g picked up (OUT2 closed), change the angle of the applied current so that it’s
in phase with the voltage and verify that OUT2 opens. This verifies that the 32-1 function is
operating in the reverse trip direction and not in the forward direction.
Step 5: (Optional.) Repeat steps 1 through 4 for B-phase and C-phase currents. (Consult the Power
(32) Protection chapter for operating details.)
Step 6: (Optional.) Repeat steps 1 through 5 using 32-2 in place of 32-1.
Step 7: (Optional.) Repeat steps 1 through 6 for settings group 1, 2, and 3.
Step 8: (Optional.) Repeat steps 1 through 7 with CT2 as the bus CT selection for protection systems
equipped with two sets of CTs. In step 2 replace D1 with F1, D2 with F2, etc.
Functional Test Report
Forward Tripping Direction (Overpower)
Pickup Setting Range = 1 to 6,000 Watts for 5A sensing
1 to 1,200 Watts for 1A sensing
Pickup Accuracy = ±3 or ±2 W, whichever is greater
Dropout should occur between 95-99% of the actual pickup value.
