Consider a station (1 1/2 schemes ) feeds with two lines
1. Line -1 dead for maintenance work
2.In Line -2 there is a Zone -1 fault
Now The Auto reclose should block because already one Line -1 is out and may be fault exist in Line -2 now the condition is station totally dead. So the station should not energized by Line-2 Auto reclose with fault line.
If the Power Transformer connected with same cross bay then it should be energized with Bus voltage. If Bus side Transformer CB in open condition then the A/R operation should block for the line.Otherwise the Transformer also energized with fault line.
