Example 2
There are two separate sequences implemented with three shots. Shot 1 is
implemented by CBB1 and it is initiated with the high stage of the overcurrent
protection (I>>). Shot 1 is set as a high-speed autoreclosing with a short time
delay. Shot 2 is implemented with CBB2 and meant to be the first shot of the
autoreclose sequence initiated by the low stage of the overcurrent protection (I>)
and the low stage of the non-directional earth-fault protection (Io>). It has the same
reclosing time in both situations. It is set as a high-speed autoreclosing for
corresponding faults. The third shot, which is the second shot in the autoreclose
sequence initiated by I> or Io>, is set as a delayed autoreclosing and executed after
an unsuccessful high-speed autoreclosing of a corresponding sequence.
