by an undervoltage condition, which in turn is controlled by the
a trip from distance in not required, then it can be disabled with the
operand to perform a trip action if the intent is apply zone 1 extension.
PICKUP RCL TRIP
The zone 1 extension philosophy used here normally operates from an under-reaching zone, and uses an overreaching
distance zone when reclosing the line with the other line end open. The
zone 1 extension functionality if external autoreclosure is employed. Another zone 1 extension approach is to permanently
apply an overreaching zone, and reduce the reach when reclosing. This philosophy can be programmed via the autore-
close scheme.
