Protection Setup
Single Phase High Voltage Threshold
This is the percentage of phase voltage above which a Three-Phase Trip operation will
occur. (Range: 100-200; Step: 1; Default: 120)
Current Supervised on Low Voltage
Specify the Yes or No (default) option.
Threshold Current
When the Current Supervised on Low Voltage mode is selected, specify the primary
current value. (Range: 10-16,000; Step: 1; Default: 800) The stated maximum is for
15-kV IntelliRupter fault interrupters; 27-kV and 38-kV models are limited to 12,500 amps
maximum.
Single Phase Time to Trip
This is the time (in seconds) the Low-Voltage or High-Voltage Threshold setting must
be exceeded for a Trip operation to occur. (Range: 0-600; Step: 0.01; Default: 30.00)
Single Phase Reset Time
This is the time (in seconds) good voltage must be present for the Single-Phase Voltage
element to reset. (Range: 0-600; Step: 0.01; Default: 1.00)
Trip on Three Phase Voltage
Specify the Yes, No (Default), or IntelliTeam SG option to enable this element. The
IntelliTeam SG setting causes this element to only be active when the IntelliTeam SG
system is in the Ready state.
Three Phase Low Voltage Threshold
This is the percentage of system voltage below which a Three-Phase Trip operation
will occur. (Range: 5-100; Step: 1; Default: 75)
Three Phase High Voltage Threshold
This is the percentage of system voltage above which a Three-Phase Trip operation
will occur. (Range: 100-200; Step: 1; Default: 120)
Current Supervised on Low Voltage
Specify the Yes or No (default) option.
Threshold Current
When the Current Supervised on Low Voltage mode is selected, specify the primary
current value. (Range: 10-16,000; Step: 1; Default: 800) The stated maximum is for
15-kV IntelliRupter fault interrupters; 27-kV and 38-kV models are limited to 12,500 amps
maximum.
Three Phase Time to Trip
This is the time (in seconds) the Low-Voltage or High-Voltage Threshold setting must
be exceeded for a Trip operation to occur. (Range: 0-600; Step: 0.01; Default: 30.00)
Three Phase Reset Time
This is the time (in seconds) good voltage must be present for a Three-Phase Voltage
element to reset. (Range: 0-600; Step: 0.01; Default: 1.00)
