Abstract :
Usually, substation grounding grid design is carried out with the aim of meeting the safety restrictions while minimizing its cost. Typically, at low frequency, a best solution based on unequally spaced grids can be obtained. In this paper, the behaviour at several frequencies of this kind of grid was analysed and compared with regular (equally spaced) grids
