The
Overcurrent Trip
function operates in both directions.
The
Hot Line Tag Profile
settings can be copied from another profile by clicking
on the
Copy From
button.
Phase Overcurrent
The
Phase Overcurrent
element will trip the IntelliRupter fault interrupter if current
on one or more phases exceeds the pickup value for the time value set by the inverse
curve or the
Definite Time
setpoint.
Phase Check box—
Select this box to configure the
Phase Overcurrent
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
Definite Time
settings are 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.
The
Hot Line Tag
mode can be applied locally using the external manual
HOT LINE TAG lever, by a command from the
Operation
screen sent through
IntelliLink Setup Software or a SCADA DNP Point command. The
Hot Line
Tag Profile
function provides much more sensitive overcurrent protection
when hot-line work is being performed. No
Test
operation is allowed after the
Initial Trip
operation, and the
Trip
operation goes directly to the
Lockout
state and
all
Close
commands are blocked. See Figure 54.
