 Action principle
Short circuit detection principle: According to the phenomenon of short circuit,the current break when  short circuit happen, the action on the basis of the protection movement power outages.
Used to judge the short circuit fault indicator diagram
As line 2# B phase 2,5,8 indicator and line 2# C phase 3,6,9 indicator turn red, but the 11,12 indicator still show white, that judged the point D happen short circuit
Used to judge the grounding fault indicator diagram:
As line 2# C phase 3,6,9 indicator turn red,but the 12 indicator still show white, that judged the point D happen grounding fault.
