function
10.2.3.2 Auto-recloser parameter settings
Operation
The operation of the Autorecloser for 3-phase operation (SMBRREC) function can be
switched
On and Off . The setting External ctrl makes it possible to switch it On or Off
using an external switch via IO or communication ports.
NoOfShots, 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.
Auto-reclosing open times, dead times
Three-phase shot 1 delay: For three-phase High-Speed Auto-Reclosing (HSAR) a
typical open time is 400ms. Different local phenomena, such as moisture, salt,
