Step 10: (Optional.) Repeat steps 1 through 9 with CT Circuit 2 as the source for protection systems
equipped with two sets of CTs. In step 5, replace D1 with F1, D2 with F2, etc.
Timing Verification (IG Mode)
Step 1: Use BESTCOMSPlus to open the Protection, Current, Instantaneous Overcurrent (50-1) screen
and send the first row of test settings in Table 192 to the BE1-11g for settings group 0.
Step 2: Prepare to monitor the 50-1 timings. Timing accuracy is verified by measuring the elapsed time
between a sensing current change and OUT1 closing.
Step 3: Connect and apply 0.45 A to BE1-11g terminals D7 and D8 (IG).
Step 4: Step the ground current up to 0.55 A. Measure the time delay and record the result.
Step 5: Repeat step 4 for the 5,000 ms and 10,000 ms time delay settings of Table 192. Record the
results.
Step 6: (Optional.) Repeat steps 1 through 5 for settings group 1, 2, and 3.
Step 7: (Optional.) Repeat steps 1 through 6 for 50-2, 50-3, 50-4, 50-5, and 50-6.
Step 8: (Optional.) Repeat steps 1 through 7 with CT Circuit 2 as the source for protection systems
equipped with two sets of CTs. In step 3, replace D1 with F1, D2 with F2, etc.

Pickup Verification (Phase Mode)
Pickup Setting Range = 0.5 to 150 A for 5A sensing
Pickup Accuracy =
Dropout should occur between 93-99% of the actual pickup value.
Step Pickup Setting
6 0.5 A (5A CT)
7 5.0 A (5A CT)
7 20.0 A (5A CT)
6 0.1 A (1A CT)
7 1.0 A (1A CT)
7 4.0 A (1A CT)
* Dropout range is calculated from the pickup setting and may need adjusted based on actual pickup.
Timing Verification (Phase Mode)
Time Delay Range = 0 to 60,000 ms
Timing Accuracy = ±0.5% or ±½ cycle, whichever is greater + 3 cycles max for currents 1.5 x pickup
