Should the conditions not persist for the specified time, the delay timer isreset and the procedure is restarted when the conditions are fulfilled again. Circuit breakerclosing is thus not permitted until the energizing condition has remained constantthroughout the set delay setting time.11.2 Autorecloser for 3-phase operation SMBRREC (79)11.2.1 IdentificationFunction Description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberAutorecloser for 3-phase operation SMBRRECO->ISYMBOL-L V1 EN7911.2.2 ApplicationAutomatic reclosing is a well-established method for the restoration of service in a powersystem after a transient line fault.
