| Abstract: | The approaches of clear-branch resistances determination and the resistance ranges of uncertain branches evaluation are described,respectively.The practical problems in the application of the proposed principles are discussed including the selection of the exciter,elimination of the effects of down lead line resistances and the way to check the complement of a test scheme.The flowchart of the diagnosis procedure based on the proposed methodologies is suggested.An experimental grounding grid with sixty branches is used as an example.The results of corrosion diagnosis show that the proposed approaches are feasible. |
