Study of Grounding Protection of Power Supply Systems

LI Feng hua, TONG Lang tao (Hunan Yueyang Electr. Power Company,Yueyang 414000,China)  
The theories of isolation inspecting in power supply systems are expounded.The calculating formulas of fault grounding resistance and grounding location in DC power supply systems are presented.As an application,the whole area grounding protection scheme of excitation loop related to generator rotator is discussed.At last the isolation inspecting applications of unbalanced electronic bridge theory to AC power supply systems or multi branched DC power supply systems are extended.
