S&C IntelliRupter PulseCloser User Manual

Reset—Select the inverse curve reset method from the drop-down list: D/T (Denite
Time) or E/M (Electromechanical) mode.
Reset Time—When the Denite Time reset mode is selected, enter the reset delay time
(in seconds). (Range: 0.000-600.000; Step: 0.001)
Denite Time 1 Min. Trip—This is the current (in primary amperes) at which the
Denite Time 1 element picks up. (Range: 6-16,000; Step: 1) The stated maximum is
for 15-kV IntelliRupter fault interrupters; 27-kV and 38-kV are limited to 12,500 amps
maximum.
Denite Time 1 Min. Time—This is the time delay (in seconds) after which the Denite
Time 1 element trips. (Range: 0.000-600.000; Step: 0.001)
Denite Time 2 Min. Trip—This is the current (in primary amperes) at which the
Denite Time 2 element picks up. (Range: 6-16,000; Step: 1) The stated maximum is
for 15-kV IntelliRupter fault interrupters; 27-kV and 38-kV are limited to 12,500 amps
maximum.
Denite Time 2 Min. Time—This is the time delay (in seconds) after which the Denite
Time 2 element trips. (Range: 0.000-600.000; Step: 0.001)
Ground Overcurrent
The Ground Overcurrent element trips the IntelliRupter fault interrupter when the
computed residual of the three-phase elements exceeds the pickup value for the time
value set by the inverse curve or the denite time delay.
Ground Check box—Check to enable this element.
Inverse Segment—Select from the drop-down list of inverse curve names or select
the None option. Only the Denite Time settings will be used when the None option
is selected.
Min. Trip—This is the current (in primary amperes) at which the inverse curve begins
timing. (Range: 6-16,000; Step: 1) The stated maximum is for 15-kV IntelliRupter fault
interrupters; 27-kV and 38-kV are limited to 12,500 amps maximum.
Min. Time—This is the time (in seconds) that denes the fastest response of the inverse
curve portion of the TCC curve. (Range: 0.000-100.000; Step: 0.001)
Time Mult—This is the time modier for the inverse curve. (Range: 0.01-15.00; Step: 0.01)
Time Adder—This is the time modier for the inverse curve. (Range: -10.000-100.000;
Step: 0.001)
Low Cutoff—This is the current (in primary amperes) at which the TCC curve begins
timing. This value must be equal to or greater than the lowest pickup value of the inverse
curve, the Denite Time 1 element, and the Denite Time 2 element. (Range: 6-16,000;
Step: 1) The stated maximum is for 15-kV IntelliRupter fault interrupters; 27-kV and
38-kV are limited to 12,500 amps maximum.
Reset—Select the reset method for the inverse curve from the drop-down list. Select
the D/T (Denite Time) or E/M (Electromechanical) mode.
Reset Time—When the Denite Time reset mode is selected, enter the reset delay time
(in seconds). (Range: 0.000-600.000; Step: 0.001)
