Abstract :
The grounding grid is commonly installed in the substation. When it´s damaged, not only restoring and improving work affects the production, but also it is difficult to carry this work out. In this paper, we will use the method that shifts the positions of the exciters among the touchable nodes and measures as much as possible for each excitation. As the equations obtained by linearizing the question are underdetermined, the preconditioned Landweber iteration algorithm is used. The results of the calculations, and the measurements in practical examples show that the proposed method is feasible.
