    The function also keeps track of shots already performed, that is, at which point the auto-reclose sequence is from shot 1 to lockout. For example, if shots 1 and 2 have already been performed, only shots 3 to 5 are allowed. Additionally, the Enable shot jump setting gives two possibilities: REF615 Application Manual…

    Example connection between protection and auto-reclose functions in IED configuration It is possible to create several sequences for a configuration. Auto-reclose sequences for overcurrent and non-directional earth-fault protection applications where high speed and delayed auto-reclosings are needed can be as follows: REF615 Application Manual…

    In this case, the sequence needs two CBBs. The reclosing times for shot 1 and shot 2 are different, but each protection function initiates the same sequence. The CBB sequence is as follows: A071270 V1 EN Figure 110: Two shots with three initiation lines REF615 Application Manual…
