Autoreclose (ARC)
The basic objective of auto-reclosing is to restore automatically the transmission line back into
service, after being tripped by line protection relays, without depending on the operator action.
The use of auto-reclosing will improve the system stability and reliability. The choice of the
auto-reclosing type, such as, one or more reclosing shots, high speed or delayed, single-phase
or multi-phase depends on the characteristics of the transmission and protective system
together with the utility practice. The suitability of a particular auto-reclosing scheme may
also be established by conducting a transient analysis study of the interconnected electrical
network.
