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 (50P-1). 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 (51P) and the low stage of the non-directional ground-fault
protection (51N/G). It has the same reclose 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 51P or 51N/G, is set as a delayed autoreclosing and
executed after an unsuccessful high-speed autoreclosing of a corresponding sequence.
