| Abstract: | In order to detect the ground grid faults without excavating or power cut,a mathematical model of ground grid is built.By using measured data of voltage between its topological structure and grounding conductor,an equation for diagnosis of ground grid faults is formulated in accordance to Tellegen's theorem.MATLAB iterative optimization algorithm is adopted for solution to mathematical model and resistance value of each subcircuit after failure is concluded,thus corrosion degree of ground grid is judged.PSp... |
