S&C IntelliRupter PulseCloser User Manual

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 time delay for
the reset (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 models 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 models 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: 0.000-6000.000; Step: 0.001)
Sensitive Earth
The Sensitive Earth element will trip the IntelliRupter fault interrupter if 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 setting.
Sensitive Earth Check box—Select this box to congure the Sensitive Earth element.
Inverse Segment—Select from the drop-down list of inverse-curve names or select
the None option. When the None option is selected, only the Denite Time settings
will be used.
Min. Trip—This is the current (in primary amperes) at which the inverse curve begins
timing. (Range: 3-16,000; Step: 1) The stated maximum is for 15-kV IntelliRupter fault
interrupters; 27-kV and 38-kV models are limited to 12,500 amps maximum.
Min. Time—This is the time (in seconds) dening the fastest response of the inverse
curve portion of the TCC curve. (Range: 1.000-6000.000; Step: 0.001)
Time Mult.—This is the time multiplier for the inverse curve. (Range: 0.01-15.00,
Step: 0.001)
Time Adder—This is the time adder 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. (Range: 3-16,000; Step: 1) The stated maximum is for 15-kV IntelliRupter fault
interrupters; 27-kV and 38-kV models are limited to 12,500 amps maximum.
Reset—The reset method for the inverse curve is congurable for the D/T (Denite
Time) or T/A (Time Accumulation) modes. The Time Accumulation mode times when
current is above the Minimum Trip value and stops the timer when current is below the
Minimum Trip value. The timer continues to count until either the SEF element trips,
or the element does not pick up for the duration of the user-specied SEF Element Reset
Time parameter and the element resets. The Time Accumulation method is the default.
