PulseClosing Technology Enabled
When set to
Yes
mode, an operation using PulseClosing Technology will be performed
before executing the closing profile to determine whether a fault is present. When a fault
is detected, the IntelliRupter fault interrupter will not complete the closing operation
and the line will not be subjected to damaging fault current. The
Yes
mode is typically
selected for the first
Closing Profile
operation, and the
No
mode is selected for the
second
Closing Profile
operation.
Time for Closing Profile to be Active
This is the time (in seconds) the closing profile remains active after the commanded poles
have closed. The assigned general profile will be active after this timer expires when no
elements in the closing profile are picked up and timing. The TCC section of this profile
should be set to coordinate with upstream devices while this profile is active. The timer
starts after the last commanded pole is closed. (Range: 0.0-600.0; Step: 0.1; Default: 2.0)
Time for External Lever Closing Delay
When the OPEN/CLOSE/READY lever is operated, this timer must expire before the
Close
operation starts. This delay does not apply to Wi-Fi or SCADA closing commands.
When this timer is set to 0 seconds, the second
Closing Profile
operation cannot be
set by the IntelliRupter fault interrupter OPEN/CLOSE/READY lever. (Range: 0.0-60.0;
Step: 0.1; Default: 5.0)
Sync Check Enabled
The
No
setting is the default for both closing profiles. Typically, the
Yes
setting is selected
for the first
Closing Profile
operation and the
No
setting is selected for the second
Closing Profile
operation.
Voltage Difference Threshold
This is the percentage voltage difference between the X and Y sides above which a
Close
operation is prevented. (Range: 5-50; Step: 1)
Phase Angle Difference Threshold
This is the phase-angle difference (in degrees) between the X and Y sides above which
a
Close
operation is prevented. (Range: 3-30; Step: 1)
Frequency Difference Threshold
This is the frequency difference (in hertz) between the X and Y sides above which a
Close
operation is prevented. (Range: 0.1-1.0; Step: 0.1)
Voltage Threshold
This is the phase-voltage level below which a
Synch Check
operation will not be
performed. The
Synch Check
mode is active when all phase voltages are above this
configured level. (Range: 5-95; Step: 1)
