STEP 9.
Adjust the
Overcurrent and IFS
elements on the
Testing After Initial Trip
screen. See Figure 74 on page 131.
(a) The
Overcurrent Trip
element can be
1-Phase Trip
or
3-Phase Trip
mode as configured by the
Initial Trip
drop down menu selection.
(b) The
Delay
setpoint is the time interval between tests.
(c) When
Pulse
mode is selected for the
O/C Sequence
setpoint, the
IntelliRupter fault interrupter will use PulseClosing Technology to test the
line for each programmed test.
(d) Configure an appropriate time for the
O/C and IFS Sequence Reset Time
setpoint. This is the duration after the IntelliRupter fault interrupter has
successfully closed during a test sequence (test 1 or test 2) until it resets to
the
Initial Trip
state.
(e) Configure the
Retain Source-Side for Test Sequence
mode to the
Yes
state. This feature prevents backfeeding a substation as the result of a
restoration event returning voltage from the opposite side while the
IntelliRupter fault interrupter has lost source voltage and is still running
the test-sequence procedure.
STEP 8.
Configure the
Test 2 TCC Curves
setpoint. Configure TCC curves for both
Direction 1 and Direction 2. See Figure 73.
