Abstract	Making use of the electric network theory and the matrix theory, the fault diagnosis equations are set up in the form of sensitivity matrix. Then the method of multiple-excitation is applied to increase the number of independent equations and resolve the problem of morbid equations effectively. By introducing the micro-disposal method and the iterative algorithm, we can use the least squares approach to solve the nonlinear equations progressively by a series of linear equations. The results of the emulation calculation and simulation experiment show that the proposed method is simple and feasible, so it can be applied to fault diagnosis of grounding grid.
