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
minal 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

times out. The

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
