S&C IntelliRupter PulseCloser User Manual

Counts to Trip
A fault-current count is dened as a fault current event followed by a three-phase voltage
loss. (Range: 1-10; Step: 1; Default: 3)
Voltage Loss Association Time
This is the interval (in seconds) between the end of an overcurrent event and the start
of the three-phase voltage loss that associates the two events to the count breaker
operations. (Range: 0.10-1.00; Step: 0.01; Default: 0.10) Use the default value unless line
voltage will be supported for a protracted period following the breaker operation.
Phase Fault Minimum Current
This is the primary current required to record a phase-fault event. (Range: 30-16,000;
Step: 1; Default: 720) The stated maximum is for 15-kV IntelliRupter fault interrupters;
27-kV and 38-kV models are limited to 12,500 amps maximum.
Phase Fault Definite Time
This is the time (in seconds) required to record a phase-fault event. (Range: 0.02-320.00;
Step: 0.01; Default: 0.02)
Ground Fault Minimum Current
This is the primary current required to record a ground-fault event. (Range: 6-16,000;
Step: 1; Default: 720) The stated maximum is for 15-kV IntelliRupter fault interrupters;
27-kV and 38-kV models are limited to 12,500 amps maximum.
Ground Fault Definite Time
This is the time (in seconds) required to record a ground-fault event. (Range: 0.02-320.00;
Step: 0.01; Default: 0.02)
Loss of Voltage Only
Specify the Yes, No (default), IntelliTeam SG, or Loops Only option to congure this
element. The IntelliTeam SG or Loops Only setting causes this element to only be
active when the IntelliTeam II or IntelliTeam SG system is in the Ready state or the
Loop Restoration mode is congured. The Loss of Voltage Only element has a 30-ampere
current threshold that inhibits the element from counting. Current must be below the
30-ampere threshold and voltage must be below the Open-Source Voltage threshold.
Both conditions must be met for a minimum of 20 ms for the Loss of Voltage Only
element to count.
Counts to Trip
A voltage-loss count is dened as normal voltage followed by a three-phase voltage loss
event. (Range: 1-10; Step: 1; Default: 4)
Open-Source Voltage Threshold
This is the voltage below which a Trip event occurs, as specified on the
Setup>Protection>General Proles>Voltage, Frequency, and Sectionalizing>Voltage
Trip screen.
Reset Time
This is the time (in seconds) for the IntelliRupter fault interrupter to be in the
Open state before the Sectionalizing Timer resets. (Range: 0-1000; Step: 1; Default: 30)
