Single-phase Grounding Fault Analysis and Study of Line Selection for the Small Current Grounding System

Yang Shuying1,Zhang Xiaoming2(1.Department of Power System,North China Electric Power University,Baoding 071003,China;2.Department of Safety Supervision,Zhaoyuan Power Company,Zhaoyuan 265400,China)  
This paper analyzes several common malfunctions in case of single-phase grounding for the low current grounding system,presents the methods for fault identification and countermeasure for grounding malfunctions,on the basis of which it studies single phase wire selection for the low current grounding system.Experiments show that this system can identify fault accurately and giving an alarm.
