Judge whether the current signal of local current signal and adjacent intelligent distribution type feeder automation terminal is more than current-carrying capacity
The upper limit, if so, judging whether described local and adjacent facility switching motional success rate is more than or equal to 2, if so, as most
Excellent facility switching makes its action, restores electricity to non-faulting region.
