S&C Instruction Sheet 766-540 17
Operation Using IntelliLink® Setup Software
Measured current at each pole-unit is displayed below the lower terminal pad
voltage, along with an arrow indicating the three-phase power-flow direction. When the
arrow points right, current is flowing from the upper to the lower terminal pad. When
the arrow points left, current is flowing from the lower to upper terminal pad. Current
flow is determined by the
Three-Phase Directional Power
element, so all arrows point
the same way. Reported current is zero and directional arrows are not shown when the
IntelliRupter fault interrupter is in the
Open
state.
Each interrupter position is shown at the bottom in the
Open
or
Closed
state.
When the IntelliRupter fault interrupter has tripped open because of a fault, the Status
box at each pole-unit will show more information:
•
TESTING—
Displays when the IntelliRupter fault interrupter is in the
Open
state
and still testing
•
TESTING-SEF—
Displays when the IntelliRupter fault interrupter is in the
Open
state and still testing for a sensitive earth fault
•
PICKUP—
Displays when one of the elements has exceeded its pickup value and is
timing to trip
Additionally:
–OC
displays when timing began because of an
Overcurrent
condition
–VOLTS
displays when timing began because of a
Voltage
condition
–FREQ
displays when timing began because of a
Frequency
condition
–GOC
displays when timing began because of a
Ground Overcurrent
condition
–NSOC
displays when timing began because of a
Negative Sequence
condition
–SECT
displays when timing began because of a
Sectionalizing
condition
–SEF
displays when timing began because of a
Sensitive Earth Fault
condition
•
LOCKED OPEN—
Displays when the OPEN/CLOSE/READY lever is locked open
•
LOCKOUT—
Displays when the IntelliRupter fault interrupter has completed testing
and gone to the
Lockout
state
Additionally:
–PulseClosing
displays when the test using PulseClosing® Technology issued a
Fault
condition and has gone to the
Lockout
state
–OC
displays when tripping was because of an
Overcurrent
condition
–VOLTS
displays when tripping was because of a
Voltage
condition
–FREQ
displays when tripping was because of a
Frequency
condition
–SECT
displays when tripping was because of a
Sectionalizing
condition
–SEF
displays when tripping was because of a
Sensitive Earth Fault
condition
•
Close Blkd-Sync Check—
Displays when the IntelliRupter fault interrupter was
attempting to close, the
Sync Check
mode was in operation, and there was a difference in
frequency, voltage magnitude, or voltage angle between the X and Y sides that exceeded
the settings in the
Closing
profile that resulted in the IntelliRupter fault interrupter
not closing
•
Close Blkd Pulse Inop—
Displays when the IntelliRupter fault interrupter was
attempting to close and did not, the test using PulseClosing Technology was not
available, and the user setting for
Conventional Close If PulseClosing Not
Available
mode was set to the
No
state
•
Close Blkd No Energy—
Displays when the IntelliRupter fault interrupter was
attempting to close and did not because of insufficient storage-capacitor energy
•
Fault-PulseClosing—
Displays when the IntelliRupter fault interrupter has completed
the test using PulseClosing Technology and gone to lockout
