Step 3: To test the negative-sequence inhibit, connect a three-phase voltage source with 120 degrees
between phases. The negative-sequence quantity is based on phase to neutral nominal voltage
(69.3 or 120). The negative-sequence inhibit setting is a percent of nominal voltage. Assuming a
4-wire connection and a nominal voltage of 120 volts phase-to-neutral, 208 phase-to-phase, a
20% of nominal setting equates to a negative-sequence voltage of 24 volts.
Step 4: Set the rate of change (sweep or ramp) for 3 Hz/s (BE1-11
g
set to trip at 2 Hz/sec), initiate the
sweep, and note that OUT2 operates. While monitoring Metering of the BE1-11
g
, reduce the C-
phase voltage to 55 volts and note the negative-sequence voltage. Continue to reduce the C-
phase voltage in 1-volt increments repeating the sweep test after each reduction until OUT2
does not
operate. Inhibit should occur at 24 volts negative-sequence. Record the result.
Step 5: Set the Negative Sequence Inhibit setting to 0%.
Step 6: To test the frequency limit inhibit function, connect a 120 Vac voltage source capable of
smoothly sweeping the frequency from 35 Hz to 75 Hz to terminals C13 (A-phase) and C16
(neutral). With a ROC setting of 2 Hz/sec, initiate a 3 Hz/sec sweep (frequency range set 60 Hz
to 57 Hz) and note that OUT2 operates.
Step 7: Set the Overfrequency Inhibit setting to 59.7 Hz and the Underfrequency Inhibit setting to 59.5
Hz. Repeat Step 6 and note that OUT2 does not operate. Pickup accuracy for over and
underfrequency limit is
±
0.01 Hz.
