Can reliably determine, within the community and bounds detection ma level and zero-sequencecurrentphase short circuit fault current, automatic removal of single-phase ground fault and phase fault.
Zero-sequencecurrent criterion, negative sequence current criterion and phase current variation can be used to improve the performance of breaker failure protection for ACF sub-bank.
