LINE PICKUP
The line pickup feature uses a combination of undercurrent and undervoltage to identify a line that has been de-energized
(line end open). Alternately, the user may assign a FlexLogic operand to the
TERMINAL OPEN
setting that specifies the termi-
nal status. Three instantaneous overcurrent elements are used to identify a previously de-energized line that has been
closed onto a fault. Faults other than close-in faults can be identified satisfactorily with the distance elements.
Co-ordination features are included to ensure satisfactory operation when high speed automatic reclosure (AR) is
employed. The
AR CO-ORD DELAY
setting allows the overcurrent setting to be below the expected load current seen after
reclose. Co-ordination is achieved by all of the
LINE PICKP UV
elements resetting and blocking the trip path before the
AR
CO-ORD DELAY
times out. The
AR CO-ORD BYPASS
setting is normally enabled. It is disabled if high speed autoreclosure is
implemented.
The line pickup protection incorporates zone 1 extension capability. When the line is being re-energized from the local ter-
minal, pickup of an overreaching zone 2 or excessive phase current within eight power cycles after the autorecloser issues
a close command results in the
LINE PICKUP RCL TRIP
FlexLogic operand. For security, the overcurrent trip is supervised by
