Chapter 6 - Current Protection Functions
Auto-reclose input block applied
In the event of a fault condition that continuously asserts the start output, when an auto-reclose block is applied
the function will not trip. The auto-reclose block also overrides the logic input block and will block the selective
The Auto-reclose function outputs two signals that block protection, namely; AR Blk Main Prot and AR Blk SEF Prot.
AR Blk Main Prot is common to Phase Overcurrent, Earth Fault 1 and Earth Fault 2, whereas AR Blk SEF Prot is
used for SEF protection.
