S&C IntelliRupter PulseCloser User Manual

Advanced PulseFinding Setup Section
The PulseFinding Technique mode is disabled when the Percent of Phase Overcurrent
Trip Reached, the Percent of Ground Overcurrent Trip Reached, and the Percent of
Negative Sequence Overcurrent Trip Reached setpoints are all set to the Off state.
Percent of Phase Overcurrent Trip Reached
This is congurable to improve the sensitivity to lower-magnitude faults. (Default: 50%;
Increment: 20%, 50%, 80%, and Off)
Note: When using the PulseFinding technique with the IntelliTeam system this setting
must be ≥50%.
Percent of Ground Overcurrent Trip Reached
This is congurable to improve the sensitivity to lower magnitude faults. (Default: 80%:
Increment: 20%, 50%, 80%, and Off)
Note: When using the PulseFinding technique with the IntelliTeam system this setting
must be ≥50%.
Percent of Negative Sequence Overcurrent Trip Reached
This is congurable to improve the sensitivity to lower magnitude faults. (Default: 50%;
Increment: 20%, 50%, 80%, and Off)
Note: When using the PulseFinding technique with the IntelliTeam system this setting
must be ≥50%.
Global Timers Section
Test Sequence or PulseFinding Technique Loss-of-Source Timeout
When this timer expires, the loss of source is considered to be permanent, the
PulseFinding Technique Sequence or Test Sequence operation is cancelled, and
further automatic operation is stopped. This timer resets when the IntelliRupter fault
interrupter is manually closed after power returns. (Range: 10-600; Step: 1; Default:
30 0 second s)
Block Test on Backfeed Timeout
If backfeed voltage remains present for longer than the specied time, the IntelliRupter
fault interrupter remains open and goes into the Lockout state. (Range: 10-600; Step: 1;
Default: 300 seconds)
IntelliTeam Event Memory Timer
The IntelliTeam system considers system protection to be active for the duration of this
timer. Congure sufcient time to ensure devices such as substation breakers or upstream
protection devices complete automatic operation before this timer expires to indicate
the end of the event and the system is stable. (Range: 1-900 seconds; Step: 1; Default: 45)
Minimum Time Between SEF Current Spikes
This congures the minimum time between current spikes before they are counted.
(Range: 10-1,000 ms; Step 1; Default: 50) It applies to the SEF Trip on Current Spike
mode on the Setup>Protection>General Prole>Initial Trip–Additional Features
screen.
