Figure 2.24-6 Single shot scheme [ARC-NUM]=S1 for an Arcing fault; CB#1 fails to reclose
Note: The permissive signal ‘ARC1-VCHK’ is required in the TPAR mode for the ARC1
SHOT1 operation, but is omitted here for the sake of clarity.
(iii)
Single shot scheme for Permanent fault
Figure 2.24-7 illustrates the behavior of the single shot scheme for a permanent fault. Tripping
of the CB#1 is executed correctly, but a further trip occurs following the reclosure of the CB#1.
Accordingly, the ARC function determines that the ARC1 operation cannot restore power
transmission in the single shot scheme; subsequently the ARC function goes to the final trip
(ARC1 FT) stage.
