Auto-recloser parameter settings

The operation of the Autorecloser for 3-phase operation (SMBRREC ,79) function can be
switched Enabled and Disabled. The setting makes it possible to switch it Enabled or
Disabled using an external switch via IO or communication ports.
, Number of reclosing shots
In sub-transmission 1 shot is mostly used. In most cases one reclosing shot is sufficient as
the majority of arcing faults will cease after the first reclosing shot. In power systems with
many other types of faults caused by other phenomena, for example wind, a greater
number of reclose attempts (shots) can be motivated.
