Overview
The “Line pickup” feature uses a combination of undercurrent and undervoltage to identify a line that has been de-energized (line end open).
For more detailed information on “Line pickup” feature, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.

Logics & highlights
Line pickup logic
Definition of Setting Parameters
LINE PICKUP FUNCTION — This setting enables and disables the line pickup feature.
LINE PICKUP SIGNAL SOURCE — Selects the signal source for line pickup protection.
PHASE IOC LINE PICKUP — Specifies the level of line current required to declare a line pickup operation when the line is reenergized.
LINE END OPEN PICKUP DELAY — Specifies the time during which the line is de-energized before the line pickup logic is armed.
LINE END OPEN RESET DELAY — Specifies the time during which the line pickup logic remains armed once the line has been re-energized.
AR CO-ORD BYPASS — The coordination timer allows the overcurrent detector to be set below the expected load current seen after reclose. When this setting is enabled (the default value), the coordination timer is bypassed. Disable this setting (removing the bypass and inserting the timer) if high speed autoreclosure is employed.
AR CO-ORD PICKUP DELAY — If the setting of the overcurrent detector is less than the load current, then it picks up during a normal re-energization of the line. This setting delays the assertion of the LINE PICKUP OP operand, allowing the recovery of the line voltage to block the scheme.
AR CO-ORD RESET DELAY — This setting extends the assertion of the line pickup output when autoreclose coordination is not bypassed.
TERMINAL OPEN — This setting allows the line pickup element to be armed from a status signal (such as breaker position) rather than from current and voltage. The FlexLogic operand assigned to this setting indicates that the terminal is opened.
It can be derived by combining the status of several devices in a FlexLogic equation.
AR ACCELERATE — This setting provides zone 1 extension functionality if external autoreclosure is employed.
LINE PICKUP BLOCK — Assertion of the FlexLogic operand assigned to this setting blocks operation of the line pickup element.
LINE PICKUP EVENTS — This setting enables and disables the logging of line pickup events in the sequence of events recorder.
