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.
