Overview
The autoreclose scheme is intended for use on transmission lines with circuit breakers operated in both the single pole and three pole modes, in one or two breaker arrangements. The “Autoreclose” element provides four programs with different operating cycles, depending on the fault type. Each of the four programs can be set to trigger up to four reclosing attempts. The second, third, and fourth attempts always perform three-pole reclosing and have independent dead time delays.
For more detailed information on “Autoreclose” element, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.
