Coordination Reset Time
The duration (in seconds) Sequence Coordination TCC curves remain active. Timing
begins after Sequence Coordination TCCs are no longer timing, meaning conditions are
below the Phase, Ground, Negative Sequence, and SEF Min. Trip settings. At the
expiry of the Coordination Reset Time Timer, Initial Trip TCCs of the selected general
prole become active. (Range: 0-600; Step: 1)
Note: A time value of 0 seconds should never be used when Communication
Enhanced Coordination mode is selected.
Enter these setpoints to configure the Coordination Reset Time.
Phase Check box—Select to congure this 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: 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.
Min. Time—This is the time (in seconds) dening the fastest response of the inverse
curve portion of the TCC curve. (Range: 0.000-6000.000; Step: 0.001)
Time Mult—This is the time multiplier for the inverse curve. (Range: 0.01-15.00;
Step: 0.01)
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. 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
models are limited to 12,500 amps maximum.
Reset—Select the reset method for the inverse curve from the drop-down list:
D/T (Denite Time) or E/M (Electromechanical) mode.
Reset Time—If 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)
Definite 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: 0.000-600.000; Step: 0.001)
