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 auto-reclosing with a short time delay.
Shot 2 is implemented with CBB2 and meant to be the first shot of the auto-reclose
sequence initiated by the low stage of the overcurrent protection (I>) and the low
stage of the non-directional earth-fault protection (I
o
>). It has the same reclose time
in both situations. It is set as a high-speed auto-reclosing for corresponding faults.
The third shot, which is the second shot in the auto-reclose sequence initiated by I>
or I
o
>, is set as a delayed auto-reclosing and executed after an unsuccessful high-
speed auto-reclosing of a corresponding sequence.
