Open-Source Current Restraint Threshold

This is the current (in primary amperes) above which a Trip operation is prevented.

(Range: 0-16,000; Step: 1; Default: 10) The stated maximum is for 15-kV IntelliRupter fault

interrupters; 27-kV and 38-kV are limited to 12,500 amps maximum.

Open-Source Reset Voltage Threshold

This is the percentage of system voltage above which the Open-Source Voltage element

is reset. (Range: 5-100; Step: 1; Default: 80)

Open-Source Time to Trip

This is the time (in seconds) the Open-Source Voltage element must be below its

threshold for a Trip operation to occur. (Range: 0.00-600.00; Step: 0.01; Default: 30.00)

Open-Source Reset Time

This is the time (in seconds) voltage must be present for the Open-Source Voltage

element to reset. (Range: 0.00-600.00; Step: 0.01; Default: 1.00)

Single-Phasing Protection and Sectionalizing

Specify No (default), Yes, or IntelliTeam SG to enable this element. The IntelliTeam

SG mode will cause this element to only be active when the IntelliTeam SG system is in

the Ready state.

Zero Sequence Voltage Threshold

This is the percentage of system voltage above which tripping will occur. (Range: 1-100;

Step: 1; Default: 15)

Zero Sequence Current Restraint Threshold

This is the current (in primary amperes) above which a Trip operation is prevented.

(Range: 10-16,000; Step: 1; Default: 50) The stated maximum is for 15-kV IntelliRupter

fault interrupters; 27-kV and 38-kV are limited to 12,500 amps maximum.

Negative Sequence Voltage Threshold

This is the percentage of system voltage above which tripping will occur. (Range: 1-100;

Step: 1; Default: 15)

Negative Sequence Current Restraint Threshold

This is the current (in primary amperes) above which a Trip operation is prevented.

(Range: 10-16,000; Step: 1; Default: 50) The stated maximum is for 15-kV IntelliRupter

fault interrupters; 27-kV and 38-kV are limited to 12,500 amps maximum.

Unbalance Time to Trip

This is the time (in seconds) the Voltage Unbalance element must be above its threshold

for a Trip operation to occur. (Range: 0.00-600.00; Step: 0.01; Default: 30.00)

Unbalance Reset Time

This is the time (in seconds) voltage must be present for the Unbalance Voltage element

to reset. (Range: 0.00-600.00; Step: 0.01; Default: 1.00)
